I know its weird. Like i said i have used this other hard disk before when i was using 98 2nd edition, then when it was about half full it starting playing up, telling me it wasnt there and re-configure the disk as its doing now. The system was quite old, but it run great apart from that so i just took that disk out. Now i have XP i thought i would try it again, but nothing. It has to be the disk i guess.
