I have a HP P6320Y desktop that has a bad c:drive. The c:drive is 1TB in size. BIOS does not recognize that the drive is even there. I took the drive out and connected it via USB. Windows/7 recognized that a drive was attached and created a disk drive D:
When I try to look at the drive using Windows Explorer I am told:
"You need to format the disk in drive D: before you can use it."
Please advise me on tools I might use to try to recover data. Ideally, I would like to recover the drive and make it bootable again. I don't know what damage the drive has. It makes no funny noises when loaded via USB.
