This hack might help if your optical drive isn’t being detected. This hack is applicable if your drives disappear after you uninstall Adaptec Easy CD Creator versions 5.01 and earlier, or DirectCD version 3.01 or 3.01c. It should also work if your drives have disappeared for no apparent reason, or after various program installations and/or upgrades. In any case, it doesn’t hurt to try it. You’ll need to restart to see our drive again—if the hack works, that is. Navigate to:
HLM\System\CurrentControlSet\Control\Class\{4D36E965-
E325-11CE-BFC1-08002BE10318}
Delete the values inside the keys UpperFilters and LowerFilters. If that doesn’t seem to work, go ahead and delete the keys themselves. You’ll need to reboot to see if you’ve had any luck after that.
