Well, I followed the advice of various FreeBSD hackers and got an Archive
Anaconda from CSC.  Unfortunately, the cable I bought at the same time was
flakey (when I'm using it /dev/sd1 isn't even recognised by my controller,
just switch back to my old cable everything's fine... but I've only got 4
connectors on it) so I've got it on my old Adaptec 1540B. It seems to come
up and be recognised fine:

...

Later on I tried to write a tape (brand new Maxell 9135) and got this:

Apr 20 19:14:29 bonkers /kernel: st0(aha0:5:0): NOT READY asc:4,1
Apr 20 19:14:29 bonkers /kernel: st0(aha0:5:0):  Logical unit is in process of becoming ready

At this point no matter how long I try it doesn't see the tape. I stuck
an old DC6150 in there and it came back with "Error 0" but no kernel
messages. Someone mentioned a patch to the NCR driver to get it to work
right with this drive. Possibly the AHA driver needs a similar patch?

Or could I just have bought a bad drive?
