I have an HP/Compaq 615 laptop with a built-in CD/DVD-RW drive. In the past, I have had no problems using the drive to read and/or write CD's and DVD's.

However, for the first time in about a year, I have tried using the drive, and nothing. I cannot get VLC to play a CD in the drive, and I cannot even get Ubuntu to see a DVD or CD in the drive. I am running Ubuntu 13.10.

Here are the results of running sudo lshw -sanitize -C disk :

       configuration: ansiversion=5 status=nodisc

Here are the results of running dmesg | grep -A8 CD-ROM :

The eject command works perfectly, but I cannot actually use any media put in the drive. I cannot see, read or write disks.

Any help would be greatly appreciated.
