Early 35470As didn't complain either.  I don't have a functional one
at the moment, but I recollect that I got a different error with this
one (in fact, it was an old HP DDS tape that wasn't coded either :-).
My current drive is a C1533, and it seems to handle the tape with no
problems, so I can't check the message.
