I have a Pioneer DVR-710 Internal DVD/CD Writer The problem is whenever I put in a CD, the drive attempts to read the disc, makes strange noises for a minute, and then stops. Whenever I try to run the drive, it says it's empty. I've had the DVD drive since Christmas, and the last time a CD worked was probably a month ago, only recently I discovered this problem. This only happens to CDs. I've tried everything - blank CD-Rs and blank CD-RWs, audio CDs, software CDs such as Nero and Photoshop, and none of them work. However, DVDs work perfectly fine. I can play DVDs and watch movies, put in blank DVD-Rs and burn data, and it all works. I've tried remounting the drive to make sure no screws were loose, and nothing changed. So I'm wondering if it's a defective DVD drive or if it's some kind of virus? Anyone know? All tips and advice are appreciated. Thanks.
