I have a Gateway M520 laptop. The CD/DVD drive does not show up on Windows. The tray will open and close just fine, the light blinks like its reading it but does not register. Windows said the device is working properly and the driver is installed. It does however register on the BIOS. WEIRD!! Please help me.
Thanks, Goom

UPDATE!! Windows now says "Windows has successfully loaded the device driver for this hardware but cannot find the hardware device.(Code 41)" The device is enabled and the BIOS still recognizes it.

Aparently it was a registry error. Something about upper and lower filters. So I guess I dont need help lol.
