Ok, I upgraded my main rig to dual 74GB Raptors, which was working fine until I tried to get my dual seagate 250GB drives which were in another machine as Raid 0 into the new rig. Well, the 74GB drives no longer work or are not detected when trying to boot, it says ntldr not detected. Anyway, that's not my biggest concern. The 2x250GB drives are non existant. They both were working fine in the other machine, but are not visible on the new machine. What gives?
