If it still spins, you could try a replacement PCB and recovery software may work. If not it would need to be sent to a data recovery center to have the platter put in a working drive (heads and PCB) for recovery.
Just google for mine AIO Recovery tools 2012 and you have all the recovery appz you´ll ever need.
I cant give you a link because I gave away my work to a guy from Australia but he wont get it anymore because he sucks as a seeder and he shared the project in a iso and I gave it to him in rar and that kind of things.
Well it looks like this http://www.downtwarez.com/foro/variado/586886-aio-recovery-tools-2012-utilidades-recuperacion-pcs.html and just google and you will find it, good luck.
I had a similar problem, my computer would not "see" an old disk I added to use as for backups. However someone suggested to download Linux, Knoppix and run it and search. It worked on several old hard drives I had laying around that I also couldn't see. Gotta be worth a shot! Good luck to you! Doug
Wow guys a lot of your suggestions are not solutions . The fact of the matter is its hit or miss to recover your drive. Im pretty sure the hard drive regenerator has to be seen either in the BIOS or in the Hirens boot CD for it to try and recover the bad sectors on the hard drive. Herman
Yeah well I hear sad stories all the time. Your system's hard drive is not a good archive repository. Laptop hard drives, forget it! There are so many places offering free cloud storage, use it or become another sad story.
Agreed Herman. It's hit or miss. Sometimes it's the drive's electronics and swapping the board for a good one from an identical drive works (not often). Mechanical damage to the mechanism varies widely and sometimes it needs to go to a specialist ($$$).
