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).
On Ubuntu 9.04:
