As i wrote you already in private mail, i don't have an idea where
you've got the misconception that a `tar cvf /dev/rft0' might have
written anything.  I'm pretty sure that it could have at most
yielded an

	if (FDTYPE(minor(bp->b_dev)) & F_TAPE_TYPE) {
		/* ft tapes do not (yet) support strategy i/o */
		bp->b_error = ENODEV;
		              ^^^^^^
		bp->b_flags |= B_ERROR;
		goto bad;
	}

...ENODEV (``Operation not supported by device'').
