I have seem to have stumbled on to this bug and now my cd/dvd, on a Toshiba laptop, is now completely unusable. I tested the the cd/dvd with Windows Vista and works without a problem to eliminate problems with the hardware.
This seems to have started with an upgrade, but I can't say which one. I mostly use the cd/dvd for ripping my CDs for my blackberry and just today this started happening (it's been a at least 3-4 weeks since I last ripped a new CD).
