There’s always a clue of how to recover data from failed hard drives. There are many failed hard drives from which you have a high success rate of recovering lost data, it depends on your options of recovery once you know exactly the failure of the failed hard drives.

Ask yourself some questions about the failed hard drives before performing data recovery.

Does the hard drive spin? If so does it click? Does the armature kick out? Do the hard drives heads vibrate to initiate? Is there an odd smell to the drive? If it doesn’t spin do you hear a slight or faint ticking sound? Does the BIOS see the hard drive? Does the BIOS see the hard drive as the correct model?
Are there funny characters showing on boot? Does the operating system blue screen?

Depending on whether it is a logical, electrical or mechanical problem, you will be able to make a realistic assessment about the success chances of a paid hard drive recovery effort.
Do these yourself before you go begging to a hard drive recovery expert

Boot from a floppy and do a read only scan of the disk. This would tell you if it is a logical error. Therefore, you will be able to decide on an appropriate strategy for fixing the master boot record. If the boot sector is lost then you should be able to decide how to go about recovering the data. If there are bad sectors in the master boot record, then attach the hard drive to another working computer as a secondary hard drive and try to recover data using data recovery software.

Open up your system’s ATX cabinet box, take out your hard drive, and closely examine the circuit board under the hard drive. Do not touch the board as static discharge can damage the disk’s head. If there are tell-tale signs of a burnt circuit board or burnt components, then you can decide for sure that its a board problem. Now that you know its a board problem, you must consult your hardware supplier or service agent to decide what to do about it.

The sure sign of a mechanical problem is the clicking sound that you will hear from the hard drive when it is trying to spin up or spin down. If this click sound is coming, then the problem is related to mechanical trouble inside the hard disk platter assembly. This, more often than not is beyond repair. If a hard drive recovery expert claims it can be repaired, then make sure that is a “no data, no pay” agreement!


Static discharge will kill a hard drive when handling… especially the internal components. Dust will destroy your data… DO NOT OPEN! In my experience I see so many hard drives destroyed by helpful neighbors when the problem was not situated internal of the hard drive assembly. Just because it clicks doesn’t always represent an internal failure.

Swapping the electronics runs the risk of further damage, especially if the revision number of the PCB is different. You will have a greater success of data recovery with less risk if the original electronics is repaired.
