I have not been able to burn CD's. Here are the outputs of various commands
(2:505)$ cdrecord -scanbus
wodim: No such file or directory.
Cannot open SCSI driver!
For possible targets try 'wodim --devices' or 'wodim -scanbus'.
For possible transport specifiers try 'wodim dev=help'.
For IDE/ATAPI devices configuration, see the file README.ATAPI.setup from
the wodim documentation.

Do you get any errors posted in "dmesg" from the kernel with respect to that drive?

If you search for "sr0" in your dmesg you will see quite a number of errors. I have only ever noted such errors when there is a hardware fault with the optical drive.
