My DVD drive no longer recognizes dvds, but does recognize CD-ROMs. When a DVD is in the drive, the computer continues to act as though there is no disc in the drive. However, when a normal CD-ROM is in the drive, it appears to work normally.
I have tested on several discs, both video and game, and the behavior is consistent.
I have also tested this on both Windows Vista and Ubuntu 9.10, and the issue remains the same.
Can anyone recommend a way to fix this?
