Hello sarahlee76, Have you tried to unistall your optical drive via the device manager? You should do so. If this doesn't resolve your issue then try the Quick Fix option in this Link: but before you do the fix uninstall any third party burning software (example: Roxio, Nero, iTunes) from your system.

Apply the quick fix then reboot your computer. You can now reinstall your burning software back onto your system. Test again to see if your issue is resolved. Let us know either way if this helps you. Make it a great day! 'In the End The Love You Take, Is Equal To The Love You Make' 'In the End The Love You Take, Is Equal To The Love You Make'.
