Crap I just got done editing your first post and asking then telling you how to do it. But the damn thing didn't take, just the link. So I'll try again. Go into device mgr and click on your IDE controller. Try to roll it over there. That probably won't work but it's the easiest to start with. If not, un-install that drive, shut down and reboot. If that doesn't do it for you then start doing system restores one at a time untill you get it back. Be patient, it can be a pain in the ass. I'd suggest doing a restore back to the first day before you installed the drive that you can.
