I didn't find anything specific to my setup so I'm sending it here.
Sorry if it's the wrong place.
This drive has worked great for a number backup/restores and happily
passed the btape test.
Debian Linux (2.6.18-3)
Adaptec SCSI 19160 PCI (part #: 1822100)
Quantum DLT-V4 Tape Drive (part #: BHBAX-BR)
If you'd like other info on the setup let me know.

We should be in file 3. I am at file 3. This is correct!
Now the important part, I am going to attempt to append to the tape.

btape: btape.c:1507 Wrote block to device.
btape: btape.c:465 Wrote 1 EOF to /dev/nst0
btape: btape.c:435 Rewound /dev/nst0
Done appending, there should be no I/O errors
Doing Bacula scan of blocks:
1 block of 64448 bytes in file 1
End of File mark.
2 blocks of 64448 bytes in file 2
End of File mark.
3 blocks of 64448 bytes in file 3
End of File mark.
1 block of 64448 bytes in file 4
End of File mark.
Total files=4, blocks=7, bytes = 451,136
End scanning the tape.
We should be in file 4. I am at file 4. This is correct!
The above Bacula scan should have output identical to what follows.
Please double check it ...
=== Sample correct output ===
1 block of 64448 bytes in file 1
End of File mark.
2 blocks of 64448 bytes in file 2
End of File mark.
3 blocks of 64448 bytes in file 3
End of File mark.
1 block of 64448 bytes in file 4
End of File mark.
Total files=4, blocks=7, bytes = 451,136
=== End sample correct output ===
If the above scan output is not identical to the
sample output, you MUST correct the problem
or Bacula will not be able to write multiple Jobs to
the tape.
=== Write, backup, and re-read test ===
I'm going to write three records and an EOF
then backup over the EOF and re-read the last record.
Bacula does this after writing the last block on the
tape to verify that the block was written correctly.
This is not an *essential* feature ...

btape: btape.c:708 Backspace record OK.
