Yes.  I had this problem in maverick, and it remains after my upgrade to
natty yesterday.

Generic symptom: "media not present"--this goes for audio CDs and DVDs and
attempts to burn discs.  Only a week ago I could play audio CDs.  It seems
to have stopped working after a failed burn attempt with k3b.  (So I ordered
a cheapy drive to rule out hw fauilure--it hasn't arrived yet).

Meanwhile, the system finds the drive.  All the tests I know how to run show
it as present, modules loaded, etc.  Googling turned up numerous identical
problems/bug reports, but no fixes.

the eject command works.

I'd love an solution to this problem as well.
