pinksTry using the MS DOS command "MOUNTVOL" as follows. In this demonstration example certain commands have been "remmed" out for safety.

rem By using the "MOUNTVOL" command USB drives used as backup-to-disk targets
rem can be either removed or plugged back in.
rem By using the "NET SHARE" command USB drives MAY be shared out to users.
