I followed tyleryoungbloods thread (4-15-2005, 07:53pm) on how to get a dell dimension 8400 (which I have) to recognize drive, when reinstalling OS, the trouble I am having, is when I go back to sata operations and reset to default (autodetect raid/ achi), pc tells me there is no sata drive in 0 slot, I then go back to sata operations put it back in combination mode, and it loads right up. what am I doing wrong
