For starters, you could run Apple System Profiler (in the Utilities folder) and check that the Superdrive shows up in the Bus section of the Devices and Volumes tab, and whether an inserted CD or DVD shows up as a sub-component to its right in the display. This would at least tell you whether the hardware is being detected.
I rebooted, and now my drive works again. I looked in the devices and volumes and the drive is showing up. I'm going to run a hardware test now just for giggles.
Thanks for the help.
