If your hard drive has failed, there's no need to panic, data recovery is possible. In this article, we'll take you through the steps that need to be taken in order to recover data from a failed hard drive.
Before you start any data recovery process, you need to make sure that your drive is still capable of holding data. A quick test can help you to do this. First, connect your drive to a computer that has the same operating system as the drive.
If an automatic drive detection feature finds your drive without any issues, it means that the drive is still capable of holding data. If the drive does not detect properly or does not detect at all, it means that your drive is not capable of holding data anymore.
Once you have confirmed that your hard drive is still capable of holding data, you can move on to the actual data recovery process. First of all, you need to make sure that the hard drive's head has been removed from the drive enclosure. Only then can you start to try and access the data on the drive.
You will need a few things before you start the data recovery process:
The first thing you need to do is to wipe the drive and remove the platters from the enclosure. Usually, this step is performed to prevent dust from building up on the platters which can cause read errors.
At this point, you can proceed to take the head out of the drive enclosure. You probably want to do this outside and away from any prying eyes as there's going to be a lot of dirt and debris on the head.
Another thing that you need to do before any data recovery process is to perform a bad sector check on the drive. This is to make sure that there are no physical issues with the drive that may be causing it to fail.
Bad sectors are usually caused by physical damage to the drive. It can also be caused by improper use of the drive, such as writing to the drive while the head is still inside.
Physical damage can also be caused by a motherboard or power supply that may have caused the drive to short-circuit, resulting in physical damage to the drive.
After you have finished the bad sector check and the head wipe, you should perform a test on the drive to make sure that there are no data errors. This is usually done by running a test sequence on the drive. If data errors are found, you may want to try wiping the drive again.
