Hard Drive Data Recovery

My client experienced a hard drive failure in his desktop computer a few weeks ago.  Since the drive was unresponsive to normal operations (trying to read it from a docking station where it was not recognized in any manner), it was sent to a well known data recovery service.  They've had the drive for a few weeks and finally responded that "the drive has electrical malfunctions that’s causing it to drop out at 2% every time. We are trying  different methods ."  I thought that recovery services could work around any technical/physical issue to recover data.  FYI, the computer was protected with an APC battery backup/surge protector.  

i am interested in insight about the likelihood of being able to recover data from a drive with electrical problems and recommendations of data recovery services that might be prepared to deal with it.

Thanks in advance for your insight.

Is it a recovery service with own clean rooms? or just one which only do software based recovery without opening the harddisk?

If they have problems recovering you might try another service.

For a good recovery agency it should be possible to recover the data. But if they have to open the case to get to the data the price would rocket. Normally recovery agencies will give you an estimate of the price and also an estimate of the chances for recovery. Maybe they are just telling you that recovery isn't possible for the estimate they presented you with.

Possibly you aren't really using a good recovery agency...

No, not possible.  They can't cover everything.  A really good recovery service would have spare hard disk controller boards to swap into the failing hard disk to cover electrical problems.  However they don't necessarily have EVERY disk controller board ever made.  And the problem may not be on the controller board but elsewhere.

The fact that they say they are trying different methods means that they haven't given up hope on the disk yet.

Which means that the computer had some protection against power problems.  Probably not relevant in this case.

it depends on the type of damage your drive suffered
if a disk track is scratched -  the info on the scratched part of course is NOT recoverable by any means
but most of other damage is recoverable

Usually they try to fix the electrical problems by replacing the logical board on the drive with a similar one. If this does not help they move the plates to an identical drive and get the data out of the drive. Have you tried with another service?

For anyone with hard drive recovery concerns, this is a good round-up of considerations and approaches.  The good news is that On Track, the service selected by my client, did recover all the data on his hard drive after a few weeks of analysis.  Needless to say, he is now a fan of cloud-based backup services!
