I have somehow modified a setting somewhere that has affected My Computer and it now does not recognize any USB drives (My Computer no longer lists the drives).

I know the drive is properly connected becasue in Windows XP on my Compaq laptop I can access and explore the drive in "Control Panel," "Performance and Maintenance," "Administrative Tools," "Computer Management," under "Storage," "Disk Management"

What do I need to do to fix My Computer so these disk drives properly show in the windoe?
Thanks.
