Hint: the "rewinding" devices do not start with an n.  This means that
after you write to them (or do a listing of what's on them, or whatever),
they will rewind the tape.  The "non-rewinding" devices start with an n --
these *don't* rewind, which is useful if you want to make multiple
archives on the same tape.  Also, if you want to position the tape (with
mt(1) (I think), for example), you need to use the non-rewinding device --
else, you'll position the tape, and then it will rewind.

Note that I don't have much experience with tape drives.
