Good  then everything is talking correctly.

    jz> how can I make  sure that I  have permission to write to /dev/st0?

Permissions on /dev/st0 should be such that if you are trying to use
it as a user:

crw-rw-rw-    1 root     disk       9,   0 Apr 11 10:25 /dev/st0


    jz> how can I check that /dev/st0 are seen from dmesg ?


This is not important now that you are able to talk to the drive.

Now  try  something like:

mt -f /dev/st0 rewind    

then

tar cvf /dev/st0 /etc
