That would almost certainly be HAL trying to read the wrong kind of track
(eg reading music or video as data).

Please file a bug bug in bugzilla and initially I'd file it against hal
as it seems that it is asking your drive to do stuff it shouldn't be.
That said the drive *should not* then lockup but a few seem to take
offence.

You may find that if you disable all the automatic drive polling for new
CD/video/audio/etc that your box then behaves and this would be useful to
check, as would what happens if you kill off hald-addon-storage
