Back when I was running BSD/OS, I had a similar problem
with an Exabyte 82xx 8mm tape backup drive;  it would
hang on output.  If I remember corrrectly, input was o.k.

Since then, under BSD/OS *and* FreeBSD, I've always piped
the output of tar into dd like this:

	su
	<password>
	cd /
	tar cvf - . | dd bs=1474560 of=/dev/rst0

The buffer size happens to hold exactly one 1.44M floppy,
but I think any large buffer would do.  Haven't had a hangup
since (about 4 years now).
