When I try to check it for errors it just closes the window when I hit start and it says it can't defrag this type of disk
He's gonna check for software it came with tonight but doesn't think he has any... and doesn't know what make or model it is...
Thanks anyway
I know this is slightly different to your problem but I have used this in the past to get past problems with USB Drives:
When you attach a USB key drive to your computer you may get an error message "USB device not recognised" this is a simple solution to the problem:
Close everything down.
Remove all USB peripherals.
Remove the power leads.
Leave the computer for about 30 minutes
Plug back in after 30 minutes and start the computer
Attach USB devices one by one.
XP has been forced to restore all its drivers.
