I have just noticed that my sata optiarc ad-7200s dvdrw drive is shown as a cd drive under the my computer screen. I have looked and downloaded the new firmware version available for the drive with no change. Does anyone know how I can get the system to recognise the drive as a dvd drive? I also have an unknown high definition audio device that does not have any drivers for it and I cannot seem to find what it actually is in the computer. Could both problems be related?
