There is nothing in dmesg about the drive, but the system has been up a while. Is there some way I can query for the cdrom drive information?

I found this in /proc/sys/dev/cdrom/info, if it means anything:

# hdparm /dev/sr0

# hdparm -I

I'll have to shutdown to refresh dmesg, or maybe open up the case and have a look.
