There is a neat utility that comes with Amanda (, or in
/usr/pkgsrc/sysutils/amanda) called tapetype.  Basically, it just writes a
bunch of stuff to the tape, and tests the size of the media based on the
number of records written.  It can take a long time, but it does make a
good estimate of the length of the tapes.  DDS tapes are rarely as large
as they are claimed to be.
