You don't indicate what platform you are on, but if it is a UNIX
platform, here is a simple shell script that I have previouly used
to blank any labels so they can then be used with auto-media management.

Copy/paste everything between the BEGIN/END lines to a file called
nsr_blank_label.sh then update the JUKE, TDEV, and SLOTS variables
to match your configs.  Then run with:

        /bin/sh nsr_blank_label.sh

# This script will take volumes from the slots listed and
