Hi Frank,

Ok - here's what I got:
ran this -
shinzon:~# mt -f /dev/st0 setblk 32768
shinzon:~# find /usr/kbmosas/std | tar zcvbf 64 /dev/st0 -T -

tar finished without error  110 files, 1.2MB
Now, read it back and BAM:

shinzon:~# tar tzvbf 64 /dev/st0

Good try Frank, thanks for the input - I really think I'm dealing with a 
hardware issue.
