The block limit on my 3B5 tape drive is 8192 bytes.  The BSD tape was
probably written with a larger block size.  This has happened to me.

The only thing I could come up with at the time was to ask someone with a
tape drive without such limits to rewrite the tape for me!  Hope you have
a way to do this.

If ATT is listening, or CDC, who make the drives, where is the limitation, and
ARE there any workarounds?  These drives also do not seem to be able to be
unloaded by software, so semi-automatic backups leave the tapes loaded and
writable...
