First of all This is my first post so if I make a couple of errors I hope u forgive me. I run win xp on a pretty quick amd main board. The HD I had installed was working ok and I removed it to redo another Hard drive. when I put the original HD back in it does not boot. it keeps saying its looking for IDE's. if I slave the drive with another HD it's says it's looking for a RAID. I have lots of data on the drive which I don't want to lose can anyone tell me whats going on.
