How many times have you experienced that sickening feeling when your hard drive suddenly fails?
How many times have you experienced that your hard disk just does not boot and all the data may be gone forever?
A hard drive failure is one of the most common problems and worst nightmares faced by computer operators all over the world. Precious data is lost either at home or in big corporate environments. What can be done in these situations?
Well, there are certain solutions that can be performed by you in order to revive your hard drive. We will talk about the solution later. First, let us discuss why a hard drive fails.
Whether the data on the hard drive can be recovered or not depends on the extent of the problem. A hard drive can be damaged due to firmware corruption, electronic failure, mechanical failure or a logical failure.
Many times your hard drive may lose data due to the combination of the above mentioned factors. A hard drive may also develop bad sectors due to which the data on those sectors is lost or becomes unreadable.
Firmware refers to the information used by the computer to interact correctly with the hard drive.
If the firmware fails or becomes corrupted, then important data on the hard drive is lost.
In case of an electronic failure there maybe occur an electrical surge that can knock out the controller board on the hard drive and make it unusable.
However data can be recovered by data recovery experts who use special data recovery software. Swapping the controller board with another one can prove to be dangerous as the information on the controller board is unique to the hard drive on which it is fitted.
