So i was swapping HDDs because San Andreas wasn't wanting to work with Vista, so i disconnected my SATA Vista drive and hooked up a regular ol' IDE. I installed XP on the IDE drive just fine, installed San Andreas, etc. But the other day I went to switch it back after about a week of not using the Vista drive, and to my horror, I found the drive to be unformatted. I have a bunch of crap on there that is replaceable, so if I can't get it back, thats fine. Either way, I can't figure out what happened, nor have i figured out how to fix it without first having to purchase software(I can't find any freeware).
Any and all help is much appreciated. ^_^
