I have had the same problem.  Apparently, taper does not see the
end-of-tape properly.  I got around this by specifying the length of the
tape in the options.  This forced taper to ask for a second tape.

Unfortunately, once you have written the multiple tapes, I have found a
much worse problem (at least on all of my machines which have the Colorado
Jumbo 250 tapes).  Taper correctly asks for the second tape but about
halfway through this second tape, it gets stuck.  The tape continues to
move repetitively back and forth but no data is extracted.  This can go on
forever and I have to abort the program.

The result is that I have been unable to use taper for multiple volume
backups at all!

Cheers,

Carlo
