I believe I'm having the same if not similar issue with my CR-R drive in Ubuntu 10.04. Been searching high and low on Google for answers and have seen a number of different posts where people claim swapping out the drive fixes the issue. Is this my only recourse? Fixing what I assume is some kind of OS/software bug by replacing the hardware is like lighting a cigarette with a Cruise missile. I've also heard tell that this wasn't an issue back in 9.10. My particular symptoms appear to be that inserting and Audio CD or Blank CD into the drive make the drive icon disappear from the Computer view. Audio CDs aren't detected in RhythmBox or SoundJuicer either. Any help would be greatly appreciated as I really want to migrate from Windows to Linux for Desktop PC purposes.
