"cdrecord -scanbus" (without any other options) should show something like: 
Cdrecord 1.10 (i686-pc-linux-gnu) Copyright (C) 1995-2001 Jörg Schilling

If it doesn't, you will need to reboot and add "hdc=ide-scsi" onto the end of 
the grub or lilo command line, which will tell linux to use scsi emulation to 
talk to the cdrecorder (hdc) becasue of limitations on ide devices.

(note: on the scan bus above the cdrw (yamaha) is on dev=0,1,0  if you have 
multiple cd/dvd drives, and want to use something like xcdroast to copy you 
should also add "hdd=ide-scsi" if hdd is the other drive. There doesn't seem 
to be any slowdown to me in using it that way, even for harddrives (though I 
don't because there might be, and hd's are rw all the time, not just when 
burning, so I don't want to chance messing things up on them)
