I just decided to test a TLZ06 on my system, and it don't want to
work. I normally play with an Exabyte 8200, and that works just fine.
(This on a 11/84 with a CMD controller)

So it might be as some suggested, that the DDS drives aren't too happy.
I tried with a DDS2 tape in it, if that matters. The system sees the
drive, and I can mount and dismount tapes, and even eject them. Reading or
writing gives errors, though.

I have not verified the drive on any other system either, so there are
several possible problems here, but I thought I'd report what I can
anyhow.
