[QUOTE=txfishers;2255522]I installed a gbc-h20li blu-ray reader/cd writer into my computer. The open and close works but the computer does not know that its ther. If i go to device manager, it is not there???
Thanks in advance[/QUOTE]
The Open/Close bit, implies that the power is OK.
But Device Manager suggest SATA lead not connected properly.
If it is then maybe your SATA Controller doesn’t like Optical drives.
To help we need more information on motherboard/controller.
