I picked up a WD 200GB SE hard drive from Dell a while back that came with a Promise ATA100 controller. I had a free IDE on my mobo (a7n8x dlx) so I just stuck it on there and didn't bother with the card, and it ran perfectly for the past few months. Then I got another HD, same kind at a day after Christmas sale. To make things easy I just unplugged my cd-rom and stuck it on the mobo. Last week I picked up a power splitter so I could plug the HD's into the card and put the cd drive back on. Everything went fine through the first boot. Once I went to reboot though, it went into a disk check. Hundreds of "no file header found at xxxx" flashed up on the screen, and when I finally got back into Windows, it had pared both of the drives down from 186GB to 127GB, and logged 120GB worth of bad clusters between the two drives. I tried disk checks, formatting, and recovery tools but nothing seems to work. Is there any way I'm ever going to get that space back? Or any chance I might be able to get a new one under warranty (if I'm even under warranty any more)? I can't imagine they'd call that a defect.
