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:
- Choose your equipment carefully (buying solid equipment generally spares you serious trouble);
- Avoid exposing your computer to risky situations;
- Get into the habit of regularly maintaining your computer;
- Download optimization software and click the “Clean” button;
- Also create more partitions or make sure you have a second hard drive;
- Avoid any direct handling;
- Contact your specialist (in the event of a failure);
- Back up your data and install good antivirus software.
