I have a WD10EAVS 1TB Caviar Green Drive which works, sometimes. When it works, all is fine. When it does not, the BIOS will not detect it and neither will anything else including Western Digital DLG program or WIn 7 Disk Management.
It will sometimes work fine but when I try to copy a few files, the drive will disappear. Then it will not appear in BIOS upon reboot. I have tried it in other computers and with USB external drive adapters and I get the same results so that the problem is narrowed down to the hard drive and probably the HD control (PCB) board.
The drive is under warranty. The significant problem is (as you may have guessed) I want a copy of the files on the drive. I do not want to go to a Data Recovery service and I probably cannot afford it. I have no problem buying a new drive and swapping out the PCB if I am reasonably sure that I can find one which is compatible.
Anyone have any suggestions?
