My XP installation recently failed after a forced shut-down. It would get to the XP screen then hang, so i thought no problem i’ll just format. But in the bios one of my SATA drives had disappeared, and it wasn’t the one XP was installed on… My system includes Asus A8N-SLI mobo, 2*120gb SATA Seagate HDD, 1*320gb SATA Seagate HDD. The 2 120gb drives are still functioning on SATA 1&2 but my 320gb will not show up in the bios. I have tried swapping cables around and plugging it into the SATA ports on the mobo i know to be working… sounding like its dead, but does anyone else have any suggestions?
