Dvd Missing From Desktop


I'm running a dual processor, mirror-front G4 with 10.3.3. I recently added a Lacie 500GB firewire drive and after restarting, both my DVD and virtual disk for Tech Tools have gone missing.

The DVD shows up in System Profiler, the tray opens using the keyboard eject and it accepts a disk, but nothing shows up on the desktop. System Profiler says the drive cannot burn, however that's not true.

I can't boot from the DVD drive and can't seem to access it at all. I've repaired permissions on my OS drive but can't think of anything else to do.

Thanks for any suggestions.
