Presumably it is a SATA CD/DVD - if so you need to go through the output of dmesg to see if it is detected on one of the SATA lines - possibly grepping for 'ata' should show something. If it's not even seeing it on a SATA line, then there is something strange with the hardware or bios configuration.
