I have 4 250GB hard drives in my self-built computer. I had unplugged them and replugged them back in, but I must have plugged at least one or two into the wrong drives. Some weird code ran for quite a while (I think it altered the registry.) I see now that I should have labeled the drives AND the cables first. (Live and learn.) Each pair of 2 (I don't know which 2) are a Raid 1 set. How do I figure out which one has my C: drive on it, and which one is its mirror? Same with the second set, but of course, different drive letter. Then, how do I get everything fixed? At this point, I can't get past the windows screen. Not sure if I should even have them all plugged in right now since I don't know which is which. Just plugging them in and running with it isn't working! Can anyone offer some real technical advice? Everywhere I ask I get lots of replies, like: Just plug 'em in and go; Didn't you take notes?; etc...
