Just fumbling along here and guessing, I don't know; can you do something like "sleep 1000 < /dev/some-harmless-cd" (maybe /dev/rcd0d) so that it is spun up before trying to mount? If you can't successfully "cp /dev/null /dev/various-cd" we know there are basic problems. -- Peter Dufault Real Time Machine Control and Simulation HD Associates, Inc.
