Most likely they are database backup tapes.  I assume by your wording that
you are using DRM so it's harder to lose db backup tapes, but not
impossible.  I believe that if you delete the volhist records of db backup
tapes DRM will lose track of them as well.  So if you have DRM you only want
to use DRM to delete old backup tapes.

Look at it this way: you've just gotten a bunch of new scratch tapes you
didn't know you had!  And for free!
