The device manager recognizes the drives.
When you put a CD or a DVD inside each of the devices they spin around but the system doesn't recognize that there is a disk loaded.
My operating system is Win98.
I've also been experiencing problems with both RealPlayer and MS Media Player when trying to listen to samples on Amazon.com.
I've been considering reinstalling Win98 from the cabs (don't have a disk) but I'm not sure if that would help or how to do it.
Thanks for you help!
