We have Python (sony?) 2 GB normal and the same problem.

SunOS4.1.2 here which I want to backup... doesn't matter where

I've seen 
dump 0dsbfu 54000 6000 126 /dev/nrst0 ...

but BSD's dump is BROKEN and I can't find new version working...
it can't detect end of tape which is VERY BAD by compressed drive. It can
sometimes store 5 GB but dump will restart dumping after error on new
tape...
