Ok, here's what I got so far. I have two 74gb raptors set up on a fasttrack raid controller. At first I had them set up in a raid 0, which for some reason would fail on me every once in a while, but when I rebooted a couple times it would come back. Since then, I've wiped the drives and set them up as individual drives. In fasttrack the only way I could do this was to set them both to seperate arrays of raid 0 with only one drive. I know that doesn't sound right since raid 0 requires 2 drives, but thats exactly how it listed it. Now I got the OS reinstalled, and since then I keep having problems with one drive. My guess is the drive is faulty. When I reinstalled the OS, I only used one drive, the working one. But the other one was connected but unpartitioned. My problem now is, if I physically remove the drive, Windows won't boot. It lists something about the boot drive missing or something, but the boot drive is there. it shows up as healthy in the raid post even. When I reconnect the unpartitioned drive, it works fine. Any suggestions? I'd like to send this drive back, and have them send me a new one, but I can't without fixing this problem or reinstalling again.
