I've been doing 'dump -b 32 -B 90000' here lately.  That is, 32KB
records and 90000KB expected to fit on the tape.  This was after a
'dd bs=32k' that errored out after 92000KB.  On the other, hand, a
test with 'dd bs=256kb' the other day bombed out after 88832KB; I
don't know what to think of this.  Aren't all TK50s the same?

Anyway, as Allison says, it depends on your record size.  Do a test
run over a couple of tapes (if you want to use tar, use 'dd bs=10k')
and see what happens.
