I have one scsi tape drive that works well (FINALLY) and one that still 
isnt working. The one that is, is a dds4 and the one that isnt is a dds2 
(tapes that is). Reading the man pages on mt and st are enough to get 
the WTF??!! response out of me. Cleaning the drive is very important, 
make sure you have a cleaning tape and run it. It may be incompatible 
media, etc.. Make sure you have the right media and the bs is set right. 
And when/if you find some clues to it, clue me in will ya? lol Thanks. 
If I manage to get to the one that isnt working (when the guy pays me, I 
might look into it further) and I figure it out, I will let you know.
