Running 13.04...I am trying to put an .iso on a DVD+R disc with Startup Disc Creator. I have started by rebooting the system. I bring up the system;then I open the DVD drive and insert a blank DVD; then I close the drive. I immediately get an error message saying that I cannot burn the blank because the drive is mounted.
Then I tried this:
and I get a error message saying the drive isn't mounted. Then I repeat what I have done. What's going on? I even tried using media from another manufacturer.Code:sudo umount -f /dev/sr0
