ok, this probably sounds crazy, but i have a computer two hard drives, one for OS and one for storage. I had XP on the OS drive and went to install windows 7. when it asked me which drive i wanted to use, they weren't labels "C" and "D" as usualy, so i couldn't tell. naturally, the one i chose was the wrong one! now i have two operating systems, and windows 7 wiped out all my stored data! first, I assume there's no way to restore the storage drive? secondly, i can't tell from windows explorer which drive is XP and which drive is windows 7! are there certain files or folders i can look for as clues? i want to format the drive that had XP on it now, so i only have one OS.
