Hi James,
I thought they'd been cycled out and the burner is still at the
friends house (they can use it at least!), but I found it in the
gzipped /var/log/messages.1.gz file:
[Plug in device]

[At this point if I have a pre-recorded CD in there, I can mount
it and everything is 100% happy. Below is what happened when I
start using cdrecord. Works OK for a while, then suddenly:]

[repeats a lot]
After this happens the drive is wedged, I need to power cycle the
drive, and also unplug and replug the cable (I think) to get it to
work again.
Hope this helps.
