Why do I still get error msgs referring to scd0??

lshw output in my case has no *cdrom entry at all.  I rebooted, opened the 
tray manually, inserted a Knoppix disk and set the BIOS to boot off the cdrom 
drive.  No luck - booted from the hard drive.  

Also,    modprobe sr_mod    gave me sg0 in /dev (?).  mount /dev/sg0 
/mnt/cdrom  gave  mount: /dev/sg0 is not a block device

 This is getting  wierder and wierder.
