No Idid not change anything in BIOS. I only ran that killdisk thing. In BIOS the primary and secondary master say not available and when I boot from XP CD it says there are no HDD installed.
There are two HDD SATA drives installed. They were in a RAID1 array. Is the problem something to do with the fact that they were in a RAID array.
I have unplugged one and tried and it still isnt visible. I would be happy with just getting one HDD available as I really dont need the RAID1 anymore for this machine.
