View Full Version : [ubuntu] Ubuntu 12.04 - CD rom not mounting

December 31st, 2012, 05:14 PM
After I installed Ubuntu 12.04 on my computer, my CDrom stopped working.
I can see it in Nautilus, I can make it eject from the Terminal, but it doesn't read anything.

This is what I'm getting

wodim --devices
