My TDK drive has no problem reading DVD disks, but will not read any CD-based game and/or data disks. Is there a problem with the "auto" file system option no longer determining file system type? Fstab & mount information is below. After inserting a CD into the TDK drive, I attempted to manually mount it with the "-t iso9660" option (w/o quotations). This did not work. I have tried Memorex & Maxwell CD-Rs, but neither (or any other CD) was detected by the TDK drive. What am I overlooking?

Are you sure it's not the drive starting to fail on you? The discs are reflective to different colors, so sometimes one kind of disc basically becomes "invisible" to the drive.

Ok, I tested the TDK DVD-+RW drive on my Windows system and I receive the same results. My next attempts will be to update the firmware (if any updates exist) and to clean the lens via a cd. While testing on my Windows system, I heard a few "scratching" noises coming from the drive when a cd was spinning.
