CD burner problems: "cannot open /dev/sg*"

First off, the problem: While trying to burn a cd from gtoaster-1.0Beta5, I get this message:

cdrecord: No write mode specified.
cdrecord: Assuming -tao mode.
cdrecord: Future versions of cdrecord may have drive depentent defaults.
cdrecord: Continueing in 5 seconds...
scsidev: '1,0,0'
scsibus: 1 target: 0 lun: 0
cdrecord: No such file or directory. Cannot open '/dev/sg*'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.

Here are the details:
I built this computer fairly recently (Jan 2004) from, so all the components are new. My CD-RW drive is a Lite-On LTR-52327S (IDE). I've just upgraded to Fedora Core 2 from Red Hat 9. The CD Burner has never worked since I've upgraded, but worked fine with gtoaster before. Currently, 'cdrecord -scanbus' shows my Lite-On to be on "scsibus1: 1,0,0" and I can read data perfectly fine from it.
After I upgraded the distribution, I upgraded the kernel to 2.6.8 and reconfigured it to get my ipod to work with linux -- iPod works PERFECTly! I'm so happy :) Anyway, 'lsmod' showed no scsi-ide, so I ran 'modprobe scsi-ide' to add the module to my kernel.
My /etc/fstab file has the line '/dev/hdc /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0' I read somewhere to try /dev/scd0 instead of /dev/hdc, but that resulted in the same error as shown above.

I don't understand why it won't work now when it worked so easily before. With Red Hat 9, gtoaster was already installed, and I simply opened it, set it up in under 5 minutes, and I was burning audio CDs. Simple!

If anyone has any suggestions, tests to run, or helpful hints, please reply. Thanks,
