I dealing with problem 1 - see previous message - I set about creating a live DVD on my development system. Now I find that I cannot seem to mount a medium in that drive. wodim --devices reports it as present and so does cdrecode. I can use the eject utility to toggle the tray open and closed. But when I load a blank dvd or cd in that unit I get nothing on my desktop - in other words I am not getting an auto mount, and I cannot do anything with dd to that dev either. wodim --devices wodim: Overview of accessible drives (1 found) : -------------------------------------------------------------------- 0 dev='/dev/scd0' rwrw-- : 'HL-DT-ST' 'DVD-RAM GH22NS30' -------------------------------------------------------------------- cdrecord -inq Device was not specified.

But cdrecord says that their is no media present although I have empirically determined that a blank dvd is in fact loaded into the device: cdrecord -load wodim: Operation not permitted.
