Nice unit.

Output (as previously suggested) of:

   $ mt status /dev/nst0
   $ lsmod

Have you had the tape on the system for a while?  Did it work before?
Have you cleaned the unit?

"Craps out" isn't sufficient.  Quote the error messages.  Look them up
on Google before posting back to list.

...so...the tape is a recent addition.  Is it new or did you get it
used?  Was it installed on the system or did you just add it?

Is your SCSI properly terminated (or not, depending).
