Hard Drive Completely Dead?
Posted on 2012-09-07
I've got two computers. The desktop has two hard drives and the laptop has one hard drive. I'm trying to completely wipe them so I can sell or donate them. I'm a software developer and know very little about hardware.
On the desktop, the two drives were bound together using RAID. I believe it was RAID 1 (mirrored). I went to try separating the drives using the RAID setup. One of the drives ended up in a failed state. I'm not sure if what I did caused that or if it was already failed.
I ended up connecting the two drives directly to the IDE controllers on the motherboard. One wiped fine with DBAN. The other did not. When I used the Ultimate Boot CD and ran HD Tune. The one drive passed all blocks. The second drive failed all blocks.
On the laptop, the hard drive was showing up in HD Tune, but not DBAN. About one third to one half of the blocks failed HD Tune's test. When I started up the computer it started saying that the hard drive had a soft error. It's now saying it has a hard error and HD Tune is no longer seeing the drive.
Are these two drives shot? If so, how do I erase them so I can dispose of the drives? If there's something I can do, what would you suggest?
