The hard drive and the PCB in brief

Before going any further, let’s take a look at the composition of these two elements. 

The composition of a hard drive

This type of drive includes a PCB, or electronic board, and mechanical components such as a platter or a motor. Generally speaking, the hard drive is made up of the following elements:

The PCB in a few words

First of all, the abbreviation PCB stands for printed circuit board. This board goes by several possible names: hard drive board, drive electronic board, or controller board. The PCB is the printed circuit on the back of the drive. The PCB is a component that can be changed or repaired depending on the situation. 

Faulty hard drive electronic board: what is the cause?

This board can be damaged in the event of an electronic failure. But what causes it? At the root of these electronic failures is either a short circuit or a power surge. These electronic malfunctions can result from a lightning strike, water damage, or an abnormal fluctuation in the power supply. In every case, the outcome is the same: your electronic board is affected. More precisely, the electronic components on the PCB are damaged. Even worse, you lose access to your data. Replacing the PCB seems to be the ultimate solution. But how do you go about it? Let’s discover the key steps for replacing this electronic component.

Replacing the PCB: eligible models

Replacing my hard drive’s board is not something to take lightly. One wrong move with this electronic component and your data will be lost. Before starting, first check the feasibility of this operation based on the model. PCBs on the following models are eligible for this board replacement:

Another criterion concerns the manufacturing date. This must be earlier than 2010.

Changing the PCB: the key steps

To change your PCB without any trouble, we invite you to follow these key steps. 

The main steps

Your electronic board has the characteristics needed to be changed, but you’re wondering how to proceed. Follow these steps to replace this electronic component:

Transferring the BIOS in 3 steps

To transfer the BIOS from the PCB, you must first desolder the chip from the old controller board. Do the same with the new board. Finally, attach the old chip to the new PCB. You can then connect your now-repaired hard drive to your computer. That’s it, you can now recover your data. 

The exceptions

While replacing your electronic board may seem simple, this operation is nevertheless not recommended on certain models due to a risk of corruption and data loss. But which brands or PCB models are at risk? Here they are:

For these hard drives, it is therefore best not to attempt this operation. The PCB cannot be changed in these cases by an individual. Taking Toshiba as an example, the ROM is included on the controller board. You cannot intervene on your own.

The last resort

If your hard drive is one of the exceptions, or if you’re having difficulty replacing this electronic system, another solution exists for changing the board. You can simply turn to a professional data recovery service to replace this board. They have the ideal conditions (a cleanroom) for this procedure. Outsourcing the board replacement is therefore a possible alternative. This solution is all the more worthwhile if the data to be recovered is valuable. In that case, you cannot afford to risk losing it.

You can now decide whether to replace the faulty board yourself or to outsource this task. You now have all the keys you need to recover your data from the board, so it’s up to you.

All the personal data concerning you is stored on your computer, and more specifically on the hard drive. If you plan to sell it, reuse it or give it away, it is important to make sure your storage media is properly erased. Permanently deleting data is relatively easy on most hard drives, in order to protect your data and prevent it from being recovered by someone with bad intentions. How this is done depends on the operating system used and the type of storage device the computer is equipped with.

What does permanently erasing personal data from a drive involve?

Most users think they can delete a file or folder simply by placing it in the operating system’s recycle bin and emptying it. This is not the case, because when this method is used, the file always remains on the hard drive. In fact, a great deal of information is recorded on the hard drive, and it is referenced in a special table which the system accesses when it needs to open the documents requested by the user. When a file is deleted by emptying the recycle bin, the file system tells the operating system that the space used by the document is free, but the file remains there until the reserved space is overwritten by another file. Consequently, permanently deleting data stored on a hard drive means writing information randomly and, if possible, repeatedly, into the memory space where the data to be deleted is stored.

How to permanently delete data from a hard drive?

As we have already mentioned, the best way to permanently delete data from a storage medium is to overwrite it. Depending on the type of hard drive you have, you can opt for certain erasure methods, including reinstalling the operating system or using third-party data deletion software.

Mechanical Hard Drive (HDD)

The process of erasing a mechanical hard drive involves overwriting the data. You can use the PC reset option, which consequently deletes the data on the hard drive. If you simply want to recycle, give away or sell your computer, the restore function makes data recovery much more difficult, especially if the data is also encrypted. If you are on a Windows operating system and want to erase your files:

You also have the option of permanently deleting your data using erasure software. What these erasure utilities have in common is that they all rewrite passes (binary ones and zeros) onto the drive you want to clean, and they do this several times in a row. The goal of this method is to make the stored data inaccessible. To use these data erasure utilities, you need to download them onto a USB drive and run them from there.

Another data erasure method for a storage medium is degaussing. Degaussing is a process for erasing a magnetic-media hard drive, based on magnetic fields. During this process, a powerful magnetic field is created (more than 10,000 gauss) which neutralizes the information present on the hard drive.

SSD Hard Drive

If you bought your computer in the last few years, you probably have an SSD drive. This type of hard drive is faster than older mechanical hard drives and uses flash memory instead of magnetic media. However, the drawback of this technology is that it is very difficult to securely delete files from an SSD. SSDs use a technique called “wear levelling” to extend their lifespan. However, a side effect of this process is that confidential data can remain on the drive even after it has been erased.

So instead of erasing the contents of SSDs with an erasure utility, it is better to encrypt them. This involves manipulating the data using a mathematical process and a key that only you know. Without this key, the files on the drive appear as garbage. Even if someone manages to recover the files after they have been erased, they will not be able to restore them.

Is it possible to recover confidential data deleted by mistake?

The various methods mentioned below can be used for permanently erasing data. However, it can happen that while using one of these methods, data is accidentally deleted from the hard drive. Although these methods are based on overwriting the drive, it is still possible to recover some of the deleted information. Indeed, even if you erase the hard drive and overwrite all the deleted files, traces of the original data remain. Writing to a magnetic medium is not as precise as one might think; when a file is overwritten, the new version does not completely cover the old one. The remaining information can be read using certain data remanence techniques used by data recovery professionals. It is therefore possible to recover confidential data deleted by mistake. However, it is worth knowing that these recovery techniques can also be used by malicious individuals to recover your personal information. The only way to make data unrecoverable is to physically destroy the hard drive on which it is stored. This way, you can be assured that no software can be used to recover your sensitive data.

Replacing a faulty hard drive printed circuit board is not an easy task. The new PCB must be matched to your hard drive. Without following the necessary steps to change your new circuit board, your hard drive will not function properly and the data will not be accessible.

Need help?

What is a PCB?

Printed circuit boards (PCBs) on hard drives supply power between the various components that make a hard drive work. If you have ever handled a hard drive, you can recognize the PCB as the green or blue board on the bottom of the device.

In extremely simplified terms, the board “tells” the hard drive how to operate. It processes signals from the computer and allows the drive to transmit information to the central processing unit (CPU). However, it is not the primary storage space for user data and it contains no mechanical components.

Common issues affecting the PCB

A printed circuit board is fairly resistant, but it can be damaged during normal operation. Some common causes of printed circuit board failure are listed below, along with tips for preventing premature damage.

Guide to replacing the PCB

Before replacing the printed circuit board, make sure it is a compatible match and that its firmware is transferred. Read this guide carefully before replacing the PCB.

Examine the printed circuit board to see if a ROM chip is present. The ROM is usually an 8-pin chip (4 pins on each of 2 sides) marked U12 on Western Digital drives, or U6 or U5 on Hitachi drives. There is generally only one 8-pin chip on a printed circuit board. You will likely find a number starting with 25 on the chip. Western Digital USB-powered printed circuit boards and some newer, higher-capacity Hitachi hard drives have 2 ROM chips, so feel free to replace both.

For Western Digital PCBs, find a white U12 marking on the chip side of the printed circuit board. A missing chip in place of U12 would indicate that the printed circuit board’s firmware is built into the controller chip. This chip can be transferred by a professional.

Once the chip has been located, replace the PCB chip. If you do not feel comfortable replacing it yourself, contact a local professional. Do not entrust this task to an unqualified party, as this chip is vital for data access. An overheated ROM chip can lead to significant damage and data loss.

If you have soldering experience and the necessary tools, you may attempt to replace it at your own risk. The tools needed are: a hot air station or heat gun, metal tweezers, a gripping tool, and optional soldering flux. Start by attaching the new board to a table with the chip ready. You can apply tiny amounts of soldering flux to the chip’s 8 pins if you wish. Set the heat gun or air station to high temperature and airflow settings. With one hand, hold the air-generating tip half an inch from the chip for 10 to 15 seconds. With your other hand, gently pull away some of the heat from the chip and try to lift it with the tweezers. Do not tear the ROM chip off the PCB: it should come off without forcing it. Repeat this with the original ROM chip. Be sure to remember which side of the chip was facing up on the board. There is a dot on the chips and PCBs in case you forget which side was facing the board. 

Next, align the ROM chip from the old board onto the new board. Apply heat for 10 to 12 seconds, remove the heat, and let the board cool. Make sure the ROM chip is firmly in place. You can now connect your hard drive and perform a data recovery.

The firmware is a computer program that ensures the proper operation of the hard drive. It coordinates the action of the platters, the electronic board (PCB) and the read heads. The origin of a firmware failure can therefore stem from a software or hardware cause. It results in a malfunction of the hard drive, which may no longer be recognised by the computer and prevent you from accessing the data stored on it. Although leading to the same consequences, firmware failures are distinct from logical failures, which result from human error.

How can you identify firmware failures?

Here are the various symptoms that should alert you. 

What causes a firmware failure?

A firmware issue can stem from a malfunction of the platters or the electronic board. Physical shocks, natural wear of the platters and read heads, or a malfunctioning read head can all lead to firmware failures.

The electronic board (PCB) can be damaged by voltage spikes at start-up or during use, as well as dust, heat and humidity.

Is data recovery always possible after a firmware failure?

Data recovery is possible as long as the individual modules are not permanently damaged and the firmware is not locked. The physical integrity of the location of the damaged modules must be sound. In this case, repairing the drive only serves the purpose of data recovery.

Generally without irreversible consequences, this type of failure means you need to call on a data recovery professional.

The dangers of DIY repair using data recovery software

Following a firmware failure, you use the drive without being able to access your files. Some people may be tempted to try to fix the problem themselves, using data recovery software. Ultimately, it is precisely this kind of attempt that can lead to permanent data loss. In the event of a more serious mechanical failure, the software will force the read heads to pass over the surface of the platters, risking scratching them, and thus making it impossible to access the data stored on them.

What should you do in the event of a firmware failure?

If you think your hard drive has a firmware failure, you should immediately shut down your operating system. This will help protect against the risk of scratching the platters. If the failure turns out to be mechanical in origin, this would worsen the damage already caused. In any case, the drive should be kept in a safe place to protect it from shocks. We then recommend that you get in touch with our lab to begin the data recovery process.

Why go through a data recovery professional?

It is recommended to go through a data recovery professional in order to minimise the risk of data loss.

Working with a professional guarantees that you are dealing with recognised experts and helps avoid data loss. With over fifteen years of experience, Chronodisk’s engineers develop their own methods and tools. The most severe mechanical cases require processing in a cleanroom, as the slightest speck of dust could damage the magnetic ferrous layer of the hard drive. Nothing more can be done for drives that have been opened in open air by individuals.

Recovering data is similar to an organ transplant and most often takes place in a cleanroom. The first step is to find a drive compatible with the faulty hard drive. The goal is to transplant electromechanical components from one to the other. The next step is duplicating the repaired drive onto a healthy hard drive. The file systems and information are then finally extracted and recovered in the technical room onto an external hard drive. Collection of your equipment, assessment of your failure and the proposed quote are entirely free of charge.

A computer, whether it’s a PC or a MAC, whether laptop or desktop, contains a very large number of parts and components that allow it to carry out all the functions we would struggle to do without nowadays.

And among all these elements, there is a very important piece of hardware that needs to be taken care of to avoid unpleasant surprises, and to be wary of when it makes too much noise: the hard drive.

Request a Quote

What is a hard drive?

It is a piece of equipment usually shaped like a more or less thick rectangular case, somewhat like a disk drive, whose purpose is to store all the data you want. It’s thanks to it that you can save your files: photos, videos, music, text documents, etc. In short, all the files you want, up to its maximum storage capacity.

All computers have at least one internal hard drive. Some contain two or even more, in order to be able to store even more data.

There is also the possibility of using an external hard drive, whose purpose is also to extend the computer’s initial storage capacity. Its second advantage is that it is easily transportable and usable: you connect the drive to another computer using the data cable, and depending on the model chosen, a power cable to an electrical outlet, so you can, for example, immediately access the data.

What are the reasons my hard drive is making noise?

A healthy hard drive makes almost no noise.

When the computer is switched on, it emits a light characteristic hum as it starts up, then a series of regular clicks during use. The more it is used, the more clicking there is.
If it makes more noise than usual and the hard drive emits loud clacking sounds, then there is a problem and you need to act without delay.

There are four main reasons that can explain a noisy hard drive:

What are the solutions to repair my hard drive?

Fortunately, a hard drive making noise doesn’t always mean it needs to be replaced, and especially doesn’t mean you’re going to lose all of your data.

There are many possibilities and solutions for repairing it if it is making noise, ranging from simple cleaning to replacing a defective part, including checking the mounting systems.

All these operations are carried out using specific equipment, such as screwdrivers specially designed for computer repairs, and the use of programs such as diagnostic software to help identify the cause or causes of a malfunction.

In any case, know that it is best to entrust the repair of your hard drive to computer repair professionals. To repair the drive, they have the experience and equipment necessary to handle your hard drive with care, find the cause of the noise, and repair your drive effectively, while preserving as much as possible the data stored on it.

A few good habits to have

Generally speaking, in order not to unnecessarily strain your computer, remember to turn it off or put it to sleep when you are not using it for an extended period. This will help preserve your hard drive, as well as your computer in general.

You’ve had trouble inserting your external hard drive into your computer and you’re wondering why it wasn’t recognized. If this is the case, there are many possible reasons behind this issue. It may come from improper use of the file system, the drivers, or the drive itself. That’s why, in the rest of this article, we’ll explain the various reasons behind this problem as well as the different ways to resolve it.

Why isn’t your external drive being activated?

When you connect your external hard drive to your computer, if it’s not recognized, the device’s power cable may be faulty. That’s why you should try plugging it into another power outlet or changing the USB cable if necessary. It’s important to check for signs of activity, such as blinking lights or the buzzing of movement inside the drive, before proceeding with any further action. If it still isn’t recognized no matter what you do, your hard drive is probably unusable.

Check the connections at the hard drive

After inserting the external drive, if it’s not recognized by your computer as a storage device, check the USB port being used. Indeed, most external hard drives feature a USB 3.0 interface. That’s why they need to be connected to a PC port designed for this purpose. This port is usually colored blue and therefore easily recognizable. In general, simply using a different USB slot is enough to fix the unrecognized hard drive issue on a PC or Mac. Restarting the computer can also fix the error at the hard drive level.

Depending on the external drive used, it may need to be connected not only to the PC via a USB port, but also to the electrical network through a power adapter. That’s why you should make sure you’re using the correct power adapter and that it’s supplying the hard drive with power.

Check the hard drive connection in Disk Management

If your external hard drive isn’t recognized as a storage medium, this may be linked to an issue at the Disk Management level. If you’re using Windows, you should:

Normally, the external drive should be displayed as a removable medium.

Resolve device driver issues

In some cases, your external drive may be recognized by other computers. The problem could then come from your device driver, which can be checked using Device Manager.

To get to Device Manager, press the Windows + X keys together, then select the device management option. Another way to get there is to type “devmgmt.msc” directly into the dialog box and run it. After this action, you’ll need to update the driver or install it if it doesn’t exist.

After performing a driver update, if your hard drive still isn’t recognized, you can use the uninstall device option to remove it from your system. On restart, the Windows operating system will reinstall the driver itself and configure it correctly when you reconnect the drive.

Initialize the storage medium and create a volume

At this stage, if your computer hasn’t recognized your external hard drive, you need to initialize it before first use. That’s why you should take a look at Disk Management. At this point,

If the removable disk only has unallocated space, you’ll need to create a new partition on the removable disk, just as on an internal hard drive. This will allow Windows and other operating systems like Mac OS to use the device.

Format the external hard drive to access it

If your external drive still isn’t recognized at this point, it may not be formatted correctly for your operating system. That’s why you should keep in mind that once you start the formatting process, it will be impossible to recover data from your external drive.

So go to Disk Management and click the “Format” option. Then, give the hard drive a name and choose an appropriate file system. In most cases, you can leave the “Perform a quick format” option enabled. Wait for the process to complete. You’ll finally have access to your external drive again. If your computer still hasn’t recognized your drive, you can seek the help of experienced professionals.

Why do hard drives usually get damaged?

Our external and internal drives can be exposed to a range of risks, which can lead to data loss. Here are some of the most common failures that cause data loss on a drive, along with ways to repair the drive.

Viruses or malware

Viruses not only harm the health of our computer, but also everything they come into contact with. Although their main purpose is to steal information, they can alter the recording and encoding of data, rendering it completely unusable. These viruses can grow to the point of fully occupying the drive’s memory, even corrupting the file system, causing crashes and preventing us from reading from or writing to memory.

How to repair this damage?

A simple solution to fix this and recover your data is to keep your operating system and antivirus software up to date. Indeed, if the drive is kept clean of viruses with a good antivirus program, the risk of data loss drops to zero.

Corrupted files (bad sectors)

Just like viruses and corrupted files, this can be a serious problem for your external hard drive. They reside on your drive, preventing any modification of data on a host drive. In many cases, bad sectors mean your hard drive can no longer be recognized by a computer. This is due to a virus or a file transfer error.

What can be done to fix this?

To avoid these kinds of problems, keep in mind that you should never remove an external drive from the USB port without first ejecting it. To do this, right-click on the hard drive with your mouse. Close all processes running from the connection between the internal drive and the external hard drive, so they can be safely disconnected and errors avoided.

You should also avoid shutting down the computer while the external drive is in use, as this kind of interruption can cause faults in the partitions.

Sudden temperature changes

This problem can lead to the death of your hard drive. Temperature changes occur when there is an electronic fault in the external hard drive, or when our computer suddenly sends an electrical surge greater than the drive’s capacity. This generates high heat that can damage the logic board.

When these problems occur, external hard drive boards can start to run more slowly or become warped, until the total failure of the drive is caused.

How to repair this damage?

To prevent this problem, make sure not to leave your hard drive connected to your computer for long periods. You should only use it when you need to copy or paste files. It is also important to check with a multimeter the voltage your hard drive is receiving, which should not exceed 5 Volts.

Your hard drive being dropped

This is one of the things you should always watch out for, as an impact or a fall can damage any of your drives. Keep in mind that external drives are mechanical parts serving a circuit. As such, an impact can trigger system failures, causing irreparable situations such as preventing you from accessing the data stored on the drive.

How to repair a drive?

You must take serious care of the drive to avoid any damage. Therefore, you should keep it away from impacts, meaning on a flat surface and out of reach of anything that could fall on it.

Wear and loss of performance over time

It is inevitable that our external hard drive will eventually become damaged, since everything that exists has a lifespan, and our hard drive is no exception. There are certain steps you can take to extend the life of your drive, such as:

Steps to recover data from a damaged hard drive

Sometimes, when you inspect your hard drive, certain important files and data are lost, and once the drive repair is complete, you may even lose all the files stored on it. Therefore, to recover this data, here are a few steps to follow:

Recover files with the CHKDSK utility

Unfortunately, the Windows CHKDSK utility does not have a graphical interface like most recovery software. It runs from the command prompt, or CMD. To use this tool, you still need to know the commands you have to run, because if you want to recover data and don’t know how to do it, you could lose it forever. Here are the steps to use CHKDSK and recover files:

Using data recovery software

If you’d rather not use your operating system’s built-in tool, you can opt for file recovery tools. These are programs such as EaseUS Data Recovery and Recuva, or Prosoft Data Rescue and Ontrack. These applications scan the drives to be repaired (storage devices such as a memory card or USB sticks) and let you search for the data to recover by file type, name, etc. They will also show you recently deleted files and let you know how recoverable they are.

To do this, select the drive to repair so the scan can run. Once the scan is complete, a deeper scan will start. Then, you’ll need to select the data to recover from the list of files to recover. Finally, click the “Recover” button to start the process.

All the methods above are good for drive recovery and restoring data from a drive. However, if you don’t have the technical skills, it’s best to turn to data recovery professionals. Our experts will first run a diagnostic on your storage media before carrying out corrective actions such as repairing it and recovering the data. This will save you time and money.

The hard drive is a central component of the computing process. Its role is to store your personal data (much like a USB stick or a CD/DVD). It protects and preserves all your documents (folders, videos, images, etc.). Every computer is equipped with an internal hard drive. However, if you want to recover your data more easily (particularly your operating system data), you can turn to a separate drive. On an internal hard drive, backups happen automatically. As for an external hard drive, a manual backup is required. When the drive deteriorates, we risk losing all our data. To avoid any inconvenience, it is important to have the right reflexes. So, how do you recover your lost data from a damaged hard drive? And how do you disassemble this component safely? Here are a few clarifications.

Recognizing the fault before disassembling your drive and recovering your data

Detecting the deterioration of a piece of computer equipment is a delicate exercise. However, when a drive is failing, major anomalies appear. But how do you identify them correctly? First of all, if a computer starts making unusual noises (clicking, humming, vibrations, etc.), stay alert. This kind of noise is never a good sign. In addition, if your internal or external hard drive is damaged, your computer may fail to access some of your files (missing, inaccessible, unrecognized, etc.). In this situation, recovering lost data becomes difficult. A few more serious signs also reveal a drive malfunction. A computer that no longer starts up properly or that freezes constantly is often the result of a failing drive.

Damaged hard drive: what are the most common failures?

The anomalies responsible for a drive’s deterioration vary. But generally, they fall into two distinct groups: failures linked to an external factor and failures resulting from an internal factor.

External causes

A faulty electrical circuit, weather events (storms, etc.)… These situations generally cause a great deal of damage. And if you don’t take care to protect your equipment, a power surge risks severely damaging your hard drive (and your motherboard). At the same time, be careful not to expose your computer equipment to excessive temperatures. Also keep in mind that water causes irreversible damage. However, a failure can also be the result of improper human handling. Indeed, accidental formatting and viruses remain common causes of failure.

Internal malfunctions

Drive failures also result from electronic or mechanical deterioration. Among the recurring failures are read head deterioration and motor wear.

Should you disassemble your drive to recover your data?

When a hard drive fails, the first instinct is to try to remove the drive, disassemble it, and repair the faulty part. However, we strongly advise against carrying out such an operation if you wish to recover your data. If you attempt to disassemble the casing, you risk corrupting the existing data inside the drive unit. Indeed, once exposed to open air, your hard drive no longer benefits from any protection. Does your hard drive seem corrupted? Two options are available to you: install repair software or contact an engineer specialized in hard drive data recovery. Only a professional should disassemble your computer and recover your personal data.

How does data recovery software work?

Before disassembling the drive, developers offer specific tools to recover your personal data. Equipped with advanced technology, this software ensures the restoration of your documents. How? The application first performs a diagnostic scan. This step is crucial: it provides the software with the necessary information about the location and hierarchy of the files. Once the software has gathered all the information, it scans the storage medium and reconstructs a significant volume of data. It then reassembles the folders one by one. The technology behind a recovery program depends on its algorithms. Each piece of software has its own advantages and its own limitations. For a minor fault, this kind of technology is well suited. However, keep in mind that you need to master a few IT tools to understand how recovery software works. Furthermore, this type of program does not guarantee the recovery of all your documents. So, if your knowledge in this area is limited, or if the fault turns out to be fairly serious, avoid using software to recover your data.

How does an engineer proceed?

Contacting a specialist is the most suitable solution, especially in the event of a serious malfunction. Data recovery experts use specific tools, which guarantees a reliable and secure service. To recover your data, the professional plans an intervention in three stages: assessment, extraction, and copying. To begin with, they carry out an initial examination. They disassemble your drive and rely on the information you have provided. Then, they connect your hard drive to sophisticated machines that will carry out a diagnostic. Once the fault has been identified, the engineer proceeds to recover the data. They then duplicate your folders and ensure that all your files are properly backed up. The engineer works in a specific environment: the cleanroom, a room where the concentration of contaminants is kept very low. In this way, the professional reduces the risk of corruption or contamination.

How can you protect your hard drive?

To protect your equipment, be sure to follow these measures:

Because your storage device can be of a different type, it is first necessary to detect the fault and any potential errors. Following an unintended manipulation of your internal or external hard drive, a fall, a virus attack, or simply after accidentally deleting your files: attempting Seagate data recovery is essential. The first step is to detect your hardware and all of your storage devices. USB sticks, SD memory cards, internal HDD 3.5″ hard drives or the latest generation M2 and NVME SSD hard drives: not all hardware meets the same standards. For optimal Seagate data recovery and depending on your operating system, it is also important to distinguish between a laptop and a desktop computer.

Removing a hard drive from a laptop requires suitable tools and is much more complicated than on a desktop. When necessary, it remains indeed simple and quick to disconnect an internal hard drive from a tower. As a user of your PC, you have surely had the choice between several types of hard drives. Whether you bought your desktop computer or a laptop already ready to use, assembled and configured, or whether you own one or more other storage media: 2 main categories of hard drives exist.

How to recognise a hard drive

Even though the internal hard drives of laptop computers are in 2.5-inch format, they fall into the category of classic HDD (hard disk drive) or SSD (solid state drive) models. The HDD is historically the oldest and is a mechanical device. Made up of platters and read/write heads, the HDD has an IDE, SCSI or SATA interface for connecting the hard drive. SATA interfaces are the most recent and have largely become the standard over time. SATA III (or SATA 6Gb/s) is indeed today the norm and equips a large majority of hard drive interfaces. Practical and simple to plug in, power and detect in your computer’s Bios, the SATA III HDD hard drive nevertheless has a limited lifespan.

More economical than SSD media and equipped with very large storage capacities (up to 18 TB of data!), these remain however more fragile and wear out over time. It can then happen that following a shock or excessively frequent read and write access to a drive’s data, this HDD drive malfunctions and stops responding. When this is the case, you then need to check that the storage medium is not damaged. A physically dead hard drive is difficult to repair and imperatively requires the intervention of data recovery and IT professionals. The SSD hard drive, more recent than the HDD, is a device that does not contain mechanical components subject to wear. The Seagate SSD uses flash memory cells, which are semiconductors. Much more resistant over time and, above all, much more powerful, SSDs are gradually establishing themselves on the IT market.

Thanks to reduced access times and, above all, read and write speeds far beyond those of HDDs (nearly 150 times faster), SSD hard drives can also fail. M2 and NVME interfaces are the main connection sources for SSDs. Here too, an SSD is easy to access in order to check whether the storage medium is properly connected and powered. While users generally prefer to use more economical HDD drives to store their most important files, the Seagate SSD is used for the operating system and programs. As transfer speeds are noticeably higher than even the most powerful HDDs, these SSDs are also more reliable thanks to the absence of mechanical components. More fragile however, care should be taken with the pins if you need to handle them. For Seagate data recovery of deleted files: the simplest approach remains using the best possible recovery software. Here is a comprehensive list of programs available for free or offering a more complete paid recovery version:

Software where you just need to click a recover button!

Offering more or less the same options and features, these Seagate recovery software tools provide a filtering system and automatic recovery of a drive’s data based on file type. Generally, you simply need to click the recover or repair drive button. Even though not all deleted data and files are recoverable depending on their age, a large part of this data can nevertheless be recovered and restored. Thanks to automatic Seagate recovery over a more or less long period of time determined by your hard drive’s capacity, these programs are simple to use. Beginners and IT novices can easily find their way around the navigation settings. Corrupted drive files, infections by a virus, a trojan or a Trojan horse, malware, or accidental deletion of personal data: Seagate recovery software remains the simplest and most economical way to recover lost data.

Make backups and attempt a system restore

Because your personal and confidential documents must be protected at all costs, do not hesitate to perform regular backups. On any type of external or internal storage device, it is indeed preferable to back up your most valuable folders. Would you like to restore data from your external Seagate hard drive? A data recovery function is then often built into your hard drive’s installation program and drivers. Seagate external models all now have features allowing you to back up and recover files and folders. If you do not know on which partition you backed up your files, folders and other data, a simple search allows you to locate them. If you notice that they no longer exist and have been deleted, recover the lost files by turning to IT professional services. These experts have powerful and high-performance tools allowing them to recover Seagate drives even long after formatting. Windows, MacOs or Linux: an internal or external hard drive must be regularly checked. All these OSs have functions for restoring hard drive data, restore points or automatic data backup on a specific date. Do not hesitate to use them, and if you are unable to recover your files: consider turning to recovery specialists or use a Seagate external hard drive data recovery program.

The Synology NAS (Network Attached Storage) server is a data storage system that lets you manage and protect your files, wherever you are, by connecting to it from home. The NAS operates via a home network and enables file transfer and backup to remote drives. But it can happen that your Synology-built NAS fails and you need to recover your data from your damaged hard drive. Can data loss be avoided? Unfortunately, these systems are not fault-free and often need to be handled by IT experts specialising in data storage. Here is some advice on repair.

How can I recover data from my Synology NAS?

Why are my files on the Synology NAS no longer accessible?

This may be a problem with the partitioning of your file systems. Partitioning a hard drive is actually the result of a physical format, ahead of a logical format. Partitions are delimited zones located on the drive that prevent data from mixing randomly. Several operating systems (Windows, Linux, Mac) can be installed on the same hard drive, but on different partitions.

This type of formatting, such as switching to Linux, is sometimes the cause of file corruption on Synology-branded NAS servers.

Check your NAS’s power supply

As with many other devices, it is necessary to carry out a physical restart by powering off your Synology unit for a moment. Try removing your hard drives one by one and turning your server back on by powering it up again.

Recover your files via the USB port or by direct connection

Has your Synology home network broadcast by the NAS disappeared, so you can no longer transfer your files via a wireless connection to your storage device? In that case, first try plugging your hard drives into a tower or a computer to check whether your data can be recovered that way. Otherwise, you can try to retrieve your files using the USB port dedicated to transfer on your enclosure. If you find that neither of these two solutions is effective in accessing the data on your hard drives, a specialist company must be called in to help you. 

Recovering files from Synology NAS units: an area of expertise

Examination and symptoms: anatomy of the Synology NAS

First, it must be determined whether one or several of your hard drives are damaged. To do this, a careful physical examination must be carried out. This involves testing the hardware to understand why the files are no longer detectable and what the source of the failure is. Experts are able to determine whether they can handle this problem and recover all or part of the NAS data.

Diagnostics and types of failure for data recovery

Recovering your data using a spare drive

Fixing a data problem on a NAS requires advanced knowledge of storage systems, particularly Synology’s. Indeed, it all depends on the type of machine:

In any case, to proceed with the repair process, complex procedures must be considered by teams of experts to recover everything, if you are still unable to connect to the Synology server.

The constant need to increase the storage capacity of hard drives places relentless pressure on manufacturers.

What’s more, energy consumption must be reduced while speed is increased, which sometimes causes enormous problems…

Recently, helium has come to be seen as an essential component in hard drive production. Indeed, its properties help substantially improve the read and write performance of drives.

A helium hard drive differs from conventional hard drives, since it takes advantage of the particular lightness of this gas to increase the rotation speed of the platters as well as the storage density of the medium.

It is thanks to its minimal mass as well as its excellent thermal conductivity that positioning can be improved, allowing manufacturers to achieve better precision and much higher densities.

Detecting and resolving leaks is therefore essential, as they risk causing the rejection of many drives during production or exposing them to field failures caused by positioning errors resulting from helium loss.

The importance of backing up your data

Nowadays, data loss is an everyday occurrence, regardless of your computer’s storage medium or operating system. Recovering your data is a complex process that requires the intervention of a professional.

Numerous technological solutions, however, make it possible to remedy this effectively.

In any case, it is thanks to a daily backup of your data that you will be able to continue your activity with peace of mind in the event of loss.

To do this, you can use any storage medium:

Thus, after any incident, recovering your data will be much simpler if you have one or more of these services in place.

How to remedy these leaks?

Among the various approaches to detecting leaks is the use of sensor-based detectors. Cleaning them can take twice as long, especially in the event of exposure to a significant leak, and their sensitivity level is rather limited, or even inaccurate in the presence of a high level of helium.

Fortunately, next-generation helium leak detectors, based on the mass spectrometer principle, are capable of processing a significant leak in under a minute and providing accurate readings. This is also the case in the presence of a high level of helium.

In addition, these state-of-the-art detectors are capable of detecting very small leaks.

This shortens the test cycle since better sensitivity means faster detection.

Note that any deviation in the position of the read or write heads is likely to disrupt the device’s operation. The seek time and access time required for data read from and written to the drive are increased as a result.

If the deviations are larger, a data track risks overwriting a neighboring track. In this situation, it constitutes a failure and data loss becomes inevitable.

Using a cleanroom

A cleanroom is a work area subject to controlled temperature and humidity levels in order to protect sensitive devices from any form of contamination, and to recover lost data with complete peace of mind. 

Among its usual characteristics are: 

It must be cleaned every day to avoid any contamination.

The use of cleanroom technology is essential for carrying out basic recovery procedures. 

For a physically damaged hard drive, for example, it must be subjected to a special procedure to recover the data in a cleanroom.

This guarantees the original condition of the medium. 

Note that without a cleanroom, there is a risk that contaminating substances will settle on the platters. 

Thus, once the hard drive’s platters are soiled, the heads may catch on the particles and scratch the surface of the platter. 

This can result in data loss, and a permanent inability to recover it.

Hard drives are used to store all kinds of files. They have evolved a great deal since they were first created. They are more powerful, have greater capacity and also cost much less. Unfortunately, their lifespan is not infinite, and it can happen that a drive becomes faulty and the data becomes difficult to recover.

How to identify the different types of faults:

Since hard drives are made up of fragile mechanical parts, it can sometimes happen that they become faulty. How? A single accidental drop or a temperature variation is enough for the drive to stop working. Constantly transporting them and plugging and unplugging them increases the risk of damage to these devices.

Even so, there are 3 categories of faults:

These different faults show up in several ways. The computer may start behaving strangely, the drive may be displayed as invalid media, an error message may appear, or the device’s storage memory is displayed as 0 bytes.
The good news is that there is generally a way to repair a faulty hard drive. In most cases, the method is simple, but it may sometimes be necessary to call in a professional.

How to recover a faulty hard drive?

First of all, when a problem occurs, it is important to have the right reflexes. This will reduce the chances of not being able to recover lost or inaccessible data. It is important to know how to proceed.

For example, in the event of a fault, it is best to turn off the drive so that there is no further damage and so that the data has a chance of being recovered.

If it is a mechanical fault, it is not recommended to use recovery software, as this could damage the drive even further. The files being sought could then, in the worst case, become impossible to recover. Finally, in the event of a logical fault, you should not continue to use the hard drive, because during repair the new data would damage the data that needs to be recovered. Moreover, if the problem is due to a drop or shock, using the drive for long minutes for diagnosis could risk damaging the platters, even though they may not have been affected before. And so the files would become damaged as well.

Nevertheless, sometimes there is nothing to be done because the drive is out of service. For example, if it is impossible to save files, the drive is likely no longer writable, meaning the files are inaccessible. But inaccessible does not mean unrecoverable.

This is why it is not advisable to repair the drive yourself, but rather to call in a professional who will know the right technique to recover the data. To assess the damage, the professional will need to open the drive in a place free of any particles (dust, hair, etc.) that could further damage the hard drive. They will know how to carry out a diagnosis to determine the problem before undertaking repairs on the media and being able to recover the files.

When a problem occurs with a hard drive, it is therefore important to go immediately to a professional. They will be able to determine the cause without causing further damage to the drive. They will know how to carry out a diagnosis and then offer a solution with an estimated price. In any case, it is not advisable to try to repair the drive yourself, at the risk of making it even more faulty and failing to recover the files.
It is also important to remember to keep your important data on another storage device to avoid permanent loss in case the data cannot be recovered.

Is your computer breaking down? Is your internal hard drive — or drives — damaged?

Nothing lasts forever, and your internal hard drives are certainly no exception! That’s why it’s always best to be prepared for the worst. After all, there’s nothing more frustrating than watching your personal data disappear. So what should you do? If you care about your files and don’t want to lose them, you’ve come to the right place.

Need help?

How to recover data from an internal hard drive?

Your computer breaks down, it won’t turn back on, and there’s no way to get your hands on your files: they’re lost! Don’t worry, we’ll help you find a solution by showing you how to get them back.

How to recover your data using a recovery drive?

If a drive fails, you can download and install data recovery software for free on your computer.
This gives you access to a non-bootable Windows operating system.
You can use a USB flash drive or a blank CD/DVD.

To start your PC using a USB flash drive:

  1. Identify the boot menu key for your PC model
  2. Turn off your PC and restart it
  3. The boot menu appears
  4. Select USB device to start the PC from the USB flash drive

If you don’t have one, you can download Linux for free and burn it to a CD or put it on your USB flash drive. This will let you access a new operating system so you can use an interface.

With this interface, you’ll be able to recover all or part of your data and copy your personal files. For a damaged PC that no longer starts up, this method is one of the best ways to recover your files.

However, it can happen that, in addition to a PC breaking down, one of its components (keyboard, screen, motherboard) is also damaged. In that case, it’s a different scenario.

How to recover your personal data by removing your internal hard drive from your PC?

If one of your components is faulty and you can no longer access your interface, all you need to do is remove the drive from your laptop or desktop PC.

You’ll then need a number of tools to get inside your computer and disconnect your internal hard drive so you can carefully remove it.

All that’s left to do is connect your drive to another device such as a PC tower or a docking station. You can also place your internal hard drive in an external enclosure.

However, if you have no computer knowledge, we don’t recommend this solution, as it could cause further damage to your drive.

How to recover your files using software or an expert?

What should you do when the first two solutions haven’t worked? If you still haven’t managed to access the interface, or if it’s impossible to copy your files after placing your drive in an external enclosure, it means your internal hard drive is damaged. You can still use software (data recovery) or call in an expert.

Software lets you recover your data without causing damage to your system, by restoring lost or inaccessible files.

If your drive is severely damaged, using software won’t allow you to recover all of your lost data. Indeed, once a hard drive fails, the data stored on it becomes very difficult to recover. If all your files seem lost and you really need to recover as many as possible, you can ask an expert for help.

In the case of a damaged hard drive, this remains the only solution for recovering your lost data and files. Even so, you’ll need to dig into your wallet, as this is a complex recovery service carried out by experienced professionals and requires time.

To conclude, if you lose your data, to recover your files from an internal hard drive you can use a USB flash drive or CD to access the interface, take apart your computer to remove the drive, use recovery software, or call an expert.

By showing you how to recover data from an internal hard drive, we hope we’ve helped you recover your personal data and/or lost files.

Price variation depending on the company chosen

Whether it involves data recovery from an external or internal hard drive, a USB flash drive, or even memory cards, it is important to choose a specialist. This choice must take into account both your needs and the price of the service. The technician handling the work must demonstrate their skill and experience.

Regarding pricing, some companies offer package-style deals. Others charge by the hour. If you prefer the repair to be carried out at your home, you should budget at least 220 euros for the specialist’s first three hours of work. Also plan for the cost of the professional’s travel and the price for any additional hours required.

For government, educational, or even commercial data recovery, companies will charge a minimum of 220 euros for the first hour. For the specialist’s additional hours, you should budget 130 euros. Recovering your data can cost between 50 and 180 euros if you opt for smaller companies.

Price variation depending on the type of fault

It is essential to remember that before fixing your hard drive’s fault, any professional must first carry out a diagnostic check to determine the severity of the fault in question. This fault can be:

However, it could also be a defect issue. In other words, the drive may be formatted, damaged, or even inaccessible. After a thorough diagnostic, the specialist will be able to give you, within 24 hours, a concrete price estimate for recovering the essential contents of the hard drive. Some companies do not require payment for the initial consultation. They analyze the fault free of charge and with no obligation. It would therefore be worthwhile to opt for these services to keep your costs to a minimum.

Electronic fault

This problem occurs when the hard drive’s electronic board is either damaged or no longer working. This electronic board can stop functioning when it is overexposed to heat. In addition, electronic shocks such as power surges, storms, or even a power outage on your electrical network can be behind an electronic fault. Before proceeding with data recovery, the technician will need to repair or replace your electronic board. To ensure the best data recovery procedures are put in place, they may take the drive into a cleanroom. Repairing and recovering data from a hard drive following an electronic fault can cost between 250 and 540 euros.

Logical fault

There is a logical fault when the file system is corrupted or when the partition tables are defective. Viruses and lost hard drive partitions can also cause a logical fault. Logical fault issues are very common and sometimes arise from improper handling of the hard drive. The process of data recovery in the case of a logical fault does not necessarily need to be resolved in a cleanroom. If you hire a specialist, they may charge between 350 and 590 euros for this type of fault.

Mechanical fault

Many causes can lead to mechanical faults in a hard drive. These include, among others, motor damage that can cause a rotation or disk-alignment problem. In addition, when the read heads damage the disk’s magnetic surface, this leads to data loss. Natural disasters, impacts, and physical deformation of the disks can also cause mechanical faults. If you notice a physical problem with your drive, keep in mind that you should never try to repair it yourself. This risks causing the systematic loss of all your data. So call in a specialist. In this type of situation, professionals estimate the cost of repair at between 150 and 250 euros.

Physical fault

Generally speaking, these faults are considered the most severe. Your drive is suffering from a physical fault if it is not recognized by your computer or if it vibrates during use. File transfer speed will be very slow, and you will often hear a metallic clicking sound while it is running. This type of fault will prevent you from accessing your data. This is what is known as a hard drive crash. To regain access to the contents of your drive, you should be prepared to pay between 590 and 790 euros.
