No matter what disc I put in the DVD-ROM drive, I get:
C:\>d: The device is not ready.
When I put in the disc, it spins up and you can hear it reading the disc. I've tried a couple different discs so I doubt all of them are bad. In the Device Manager, I can see the DVD-ROM driver and it says the device is working properly, and there aren't any updated drivers.
What would be the next steps in determining the root cause of this problem (short of replacing the hardware completely)?
