I have a computer that has an Aopen 56x cd-rom and a Plextor CDRW. Whenever I play an audio cd in the Aopen, the hard drive led blinks simultaneously with the cd-rom access light. When I play the same cd in the Plextor, the hd led doesn't blink. It does this both with and without the audio cable on the Aopen. Any ideas what could be blinking when using the Aopen? I guess it's not a serious problem, but I was just curious. Thanks.
