Hi guys, I have a HP laptop which I have formatted and restored XP to. I backed up all the docs etc onto the external USB drive prior to the format. Now I want to restore the backup I cant. When I plug the drive in it locks the PC and I have to shut the PC down by holding down the power switch, not even ctrl, alt , del works. I have tried the drive on another PC and it is still fine. I have tried other USB ports - the same thing happens. The USB mouse works fine. I have disabled the legacy USB setting in the BIOS but same problem.
