Your clock is off, dude. It's been about 5 hours.
Anyway, everything went fine. I installed the small drive as SATA master, installed Windows to it, copied over the data I wanted from the beat-up drive, took it out, stuck it back in the box that the new drive came in. Yay!
So it was a pain in the ass, but I guess it was worth it. Now I don't have to worry about downtime while I wait for my big drive to get shipped back to me.
EDIT - Oh, but I have a question. It's been a long time since I've fucked with partitions. My main drive is now E:, and that's silly since it's the system drive. Of course it makes little difference in the long run, but can current versions of Windows just switch the drive designation without causing problems, or is it just as infuriating as it always was? I know next to nothing about current file systems, and I never really used NTFS before XP.
