A hard drive is not infallible computer hardware. Although it is robust, several elements or factors can cause damage to it. This is the case with electrical faults. Sudden drops or surges in electrical voltage are among the main reasons why electronic damage occurs on storage devices. That’s why you need to identify them in order to better avoid them!
Causes of electrical faults on a hard drive
Several causes are behind electrical faults on a hard drive. These include:
- Electrical shocks: power surges, power outages, deterioration of the drive’s electrical components, lightning, storms, etc.
- Improper handling of power supplies
- Short circuit at the electronic board level
- Excessive heat causing a fault, or overexposure to heat
- Use of a faulty electrical network
When these incidents occur, they can lead to a read head crash and damage them. As a result, your files can become corrupted and you may have difficulty recovering them.
Hard drive electrical faults: a few symptoms
Do you think your hard drive has suffered the effects of an electrical fault? To be sure, you need to run some checks. If it’s an internal storage device, turn on your PC; if it’s an external drive, connect it to your PC via USB. In both cases, if the device does not appear and its content is inaccessible, this may indicate electrical damage.
Furthermore, if a burning smell comes from your storage device, or if smoke is coming out of it, an internal electronic component may be corrupted or damaged.
What are the consequences of electrical faults on a hard drive?
The major consequence of an electrical fault on a hard drive is inaccessibility to your important data. This data can be permanently lost if you don’t pay attention to it. We generally always recommend that storage device owners perform occasional and regular backups of their files.
Several storage solutions are available to you: cloud, USB drives, external drives, servers, etc. This way, if your primary storage device fails, you have a back-up plan to recover the files you have lost.
How can you limit the risk of electrical faults on a hard drive?
To protect against electrical faults on a hard drive, it is recommended to use a UPS (uninterruptible power supply) or a voltage regulator. These are devices that prevent and limit the risk of undervoltage and overvoltage. As such, they prevent electronic risks and directly protect your storage devices against electrical damage.
In the event of an electrical fault, these devices ensure that it does not affect your laptop or desktop computer, and consequently, your hard drive.
How to recover data in the event of an electrical fault on a hard drive?
Electrical faults can occur on a hard drive at any time, without warning. If you have not taken protective measures against them, you could lose all the data stored on the device. What should you do when this happens? We do not recommend opening the device or attempting to recover your files yourself.
Stop using the storage device
Furthermore, we also recommend that you stop using your storage device. This reduces the risk of total data loss and makes it easier for professionals to restore your data.
Do not open the hard drive
Another mistake to avoid is trying to open the drive or recover your data yourself. First of all, if you don’t have the right equipment, you could make the fault worse. In addition, by deciding to open your storage device yourself, you expose it to dust and fine particles that can damage the read heads.
Call in professionals
The safest solution in the event of an electrical fault on a hard drive is to call in data recovery professionals. At Chronodisk, for example, we have all the expertise, know-how, and skills needed to resolve any fault situation.
First, we perform a full scan of your storage device to determine the cause of the fault and the appropriate solutions to apply. We work in a cleanroom to ensure the safety of your device and the protection of your data.
The various electrical faults affecting a hard drive are the main causes of electronic damage to your storage devices. They generally damage the read heads and result in your data becoming inaccessible. That’s why you should always back up your files to protect against loss, or call in professionals once the damage has occurred.
