You don't need to update drivers for an optical drive. They are contained within the operating system.
Ok, the next test is to try a different brand of cds. Just to see if it will burn a cd. DVD burners have two separate lasers for burning...one for dvds, one for cds. They operate at different frequencies. If the cd laser is dying, and won't function properly and it is possible for the drive to burn dvds just fine, but not cds.
You might look for an update for the firmware in your drive. The current one is 1.01. After poking around a bit, I've found out that your Optiarc is actually a re-badged Lite-On drive, the DH-20A3P.
If you are interested, you might ask in our Lite-on forum how to crossflash the drive with Lite-on firmware.
