My CD-writer doesn't appear in the list of available devices.

• Make sure that you have turned on the power for your CD-writer. Make sure that the CD-writer is connected to an appropriate power source.

• Check to make sure that your CD-writer is correctly connected to your Macintosh system.
  
  If you’re using an internal CD-writer, check that the ribbon cable is firmly seated onto the back of the CD-burner and that you have connected the power cable to the CD-writer.
  
  If you’re using an external CD-writer, check that the data cable is firmly connected to your Macintosh, and (the other end) to your CD-writer. With an external SCSI CD-writer, you also need to make sure that the SCSI ID number is set correctly, and that the SCSI termination is correct for your CD-writer. Refer to the Owner’s Manual supplied with your SCSI CD-writer for SCSI ID and SCSI termination information.
