Hi Alistair,

Good suggestion - I've rebooted and am running the box with one of the 
DVDroms connected to an external PSU. I'd now expect the one on the 
internal rail to be the failing one, if either fails.

I'm done ripping CDs for now, but I'm checking to see if I can trigger 
the same ripping DVDs.

Yours,
-S
