Try this. Power off the drive. Disconnect the drive. Reboot the computer.
Reconnect the drive. Power up the drive manually.

SP2 made some big changes to USB I have seen some older USB webcams that
won't work with SP2 until they have a firmware upgrade. If the USB drive is
very old it might be a similar problem.
