Well, I'm going to ask the obvious since you didn't cut and paste your
prompts:
Are you logged in as root when you execute the mt commands?
Tape drives often have unusual permissions on their /dev entries. In
addition, for devfs I seem to recall that you have to edit some file to
set the permissions rather than doing a direct chmod on the entry.
Another question along the same line of inquiry:
is the "mt" command aliased to something else?
Have you tried the non-action command mt -f /dev/st0 status
Have you looked at the permissions of /dev/st0?

I am a member of group disk and can therefore read and write.
