Given that it's sold as a 16x DVD burner, that's pretty unlikely. Also the
specs ( I recommend people try btc.com.tw, not btc.com if they're looking for
info! ) state the max transfer rate is 66MB/s, which is udma4.

Burner - yes. chipset is nvidia. There's nothing available on the website, just
to say it's built-in. Kernel's latest HH, 2.6.24-21-generic, 64bit, so it looks
like /dev/hdx is still alive for debian based (E)IDE interfaces.

Cable is 80 wire, and I've tried a spare with no change. The DVD is running in
cable select mode, but I have tried hardwiring as master. I've tried all the
poot options I can find suggested by google ( last one was all_generic_ide ).
It really does look like the core of the problem is that an 80 wire cable isn't
being recognised... but why??
As it's my primary workstation, I really don't want to upgrade to II *just* yet!
Cheers,
Steve
