Reading the docs for 1 minute more  :-) , would have reduced this to
a much more reasonable value, like 6-8 hours.
Just give the "-e 200g" parameter.

On the other hand, it could also be that you have connected your
ultra modern tapedrive to an antique scsi-bus limiting the speed
to 2Kbytes/sec instead of 15 Kbytes/sec or so.  What is the speed
given in the manufacturers specs?

If you really have such a combination, then even filling one tape
would take 28 hours!  Restoring would be a nightmare...

thought I'd share it with the list in case it helps someone else:

define tapetype HPLTOC7972A {
    comment "just produced by tapetype prog (hardware compression off)"
    length 213576 mbytes
    filemark 974 kbytes
    speed 2116 kps
}
