This is possibly something to do with any software you installed that pertains to the optical drive. Certain apps were known to cause problems.
If your burning software uses a "virtual drive", it may be the drive letter it has allocated, or the actual feature itself that causes a problem. You should be able to disable said feature from the software.
Something that could also maybe cause it would be the windows cd burning service
"IMAPI CD-Burning COM Service".
You need Admin rights for what follows.
If confident, go to
control panel/administrative tools/services. find the
IMAPI CD-Burning COM Service and double click it. In the centre of the window that opens, you see a drop box with
startup type next to it. Click the selector on the right of the box and highlight "disabled".
You return to the window. Click apply. If the service status shows running, click stop, then ok. If it isn't running, just click OK.
Note that doing this prevents windows from using it's inbuilt burning features. If you use Nero or similar, then it's no loss to you.
Reboot for good measure and see what happens.
Note that sometimes uninstalled software will leave conflicting drivers behind.
Anyway, Check your cd software and report back.
