A similar thread to this has been posted, but my problem is slightly different.
On startup I get the message
Primary Master:<SATA device not found>
Secondary Master:<SATA device not found>
The computer then progresses to the WindowsXP startup screen, then closes down and restarts.
I have checked the Serial ATA cables and connections, reset using the jumpers, and even removed the battery to completely reset to default settings. None of these things worked.
My motherboard is ASUS K8S-MX
