My son and I bought two computers at a computer fair earlier last year.A problem with my sons motherboard prompted us to put his hard drive as a slave in mine till we could fix his own which worked well.He took his hard drive out to place in another computer of a friend to copy a game and now his hard drive will not work,has a windows protection error and we do not know how to fix this without fdisking the drive.Can someone help me?The harddrive is a 40 gig maxtor.Any help or suggestion will be appreciated,thank you.
