How To Recover From A Hard Drive Failure

Unfortunately, most home users and many business users do not back up their systems. Also, many small businesses have older backup procedures that are often ineffective at recovering files.

Of course, you can go to your neighborhood electronics store and buy a replacement disk for your computer, but what about the data from the crashed hard drive? How important was it? Did you save or backup it?

What to do:

If you need to recover data on the hard drive, the first thing to do is avoid trying to reboot or do anything that involves the drive. Doing so may further damage your data.

The only irreversible data loss is due to bit overwriting, physical damage to drive disks, or destruction from magnetizing platters, which rarely happens in the real world. In most cases, the malfunction is caused by a damaged circuit board, failure of a mechanical component, and failure of the internal software or firmware system track.

In the event of a real hard drive failure, only a data recovery professional can recover your data. And just because you can’t access your data through your operating system doesn’t necessarily mean that your data has been lost.

As a “rule of thumb,” if you hear a clicking sound coming from your hard drive, or if your S.M.A.R.T. The function indicates an error during the boot process, something is wrong. You should stop using the hard drive immediately to avoid causing further damage and potentially rendering the information on the hard drive unrecoverable.

After receiving your faulty hard drive, the first step for a data recovery specialist will be to attempt to save an image of the damaged drive to another drive. This imaging drive, not the actual damaged drive, is where the data recovery specialist will attempt to recover the lost data.

The next step in the imaging process is to determine if the hard drive failure was an actual malfunction, a system corruption, or a system tracking problem.

System corruption and system tracking issues are usually fixed using specialist data recovery software. System corruption or system tracking recoveries do not require processing in a clean room environment.


Unfortunately, damage to the circuit board of a unit or failure of main units is not uncommon. In each of these failures, a data recovery specialist should work on the system only in a clean room environment. There, the specialist can replace parts such as drive electronics, internal components, read / write arms, read / write heads, spindle motors, or spindle bearings from a donor drive to access data from the failed hard drive. In most cases, the data recovery specialist can recover and return the lost data.
