[ubuntu] Ubuntu 11.10 not recognizing CD-Rs

I was able to burn a few CD-Rs, but then Brasero (and even Ubuntu itself) stopped recognizing the fact that there was a blank CD-R in the drive.

I have rebooted the system twice to try to fix it with no avail.

Going off of previous threads regarding this topic (or similar), I have the output from the following commands:

Code:

Any help at all would be appreciated.
