DUMP frigging factors for the TLZ04

[Alec D.E. Muffett]

	We have received 2 TLZ04 DAT drives to bolt onto our DS5000/200.
There is a problem with this (even though we wanted them).  We are only
running Ultrix 4.0 (rev 179) and DEC won't give us 4.1 because it's tied
up in red tape somewhere.  We're working on that, but in the meantime:-

1) We can read/write to the TLZ04's, using 'tar', for instance.  Is
	anyone out there CERTAIN that tapes written under 4.0 could be
	read by the drives under 4.1 (it seems likely, but you know how
	it is...).  The only thing which doesn't work properly is some
	bits of the 'mt' command, which presumably cannot enquire the
	device properly under 4.0, and the lack of the DDS tape
	partitioning facility.

2) Does anyone know decent 'fudge factors' to plug onto the DUMP command
	in order to make it give sensible timing values ? I saw these on
	the net a while back, but we weren't sure what we were getting,
	back then.
