You generally don't mess with tapes in anything but blocks. At least,
that's my best estimation of why there aren't any character devices for
the tape. The drivers were written by Julian Elischer a while back and
we just implemented the low-level parts.

Ack! Did you have any panics or errors or anything in the process?

Yes. I used a tape drive a while ago, but I haven't tried it recently.
It was a QIC drive and I no longer have it. :-(
