Your hard-disk may be dying or you may have a problem with the cable/the
controller.

What sort of disk is this ? If it's an old IDE model, is your ribbon cable
a 80-wire one ?
It may be worth it to change it. You may also want to reduce DMA speed as
a workaround (you should be able to do it from the BIOS).
