You've checked that you have SCSI tape support in your kernel, and that
the module (st.o, I think) is loaded?

Always rewind a tape when you're finished accessing it, since (at least,
with floppy tapes) the header segments don't get written until
you rewind (it's like 'sync' on a hard drive).
The 'mt' program is used to control a tape drive (erasing, rewinding,
status, etc) - see the man page. To see what's on the tape, use
'tar -tf /dev/st0'.
