Cannot Access CD ROM Drive On HP Pavilion Notebook

I cannot access my cd rom drive. I look in the drive section under computers and I see the C drive and the D recovery drive but no cd rom drive. I go to device manager and don't see anything relating to a cd rom drive. I have an HP Pavillion Notebook DV 9810 US and the cd rom drive itself is Lightscribe. I have tried to go into the registry through cmd, regedit and control etc but found no upper filter nor lower filter to delete. Instead when I click on the last folder,4d36e965 I see 0000 and properties. In the upper right I see default, class, class desc, enum prop pages, icon path, installer 32, no install class, silent install.
