I‘ve Ubuntu Linux Installed on HP Desktop system. When I press the eject button my DVD / CD ROM nothing happens. Linux is not ejecting my CD/DVD and I had to reboot my computer to just get CD/DVD out of drive. How do I fix this issue?

You don’t have to reboot the system to just eject CD / DVD from drive. Sometime Linux locks down your CD / DVD if a process reading / accessing file / directory on that DVD / CD.

Find Out CD/DVD drive mount location

Run df or mount command to find out location, enter the following at terminal / shell prompt:

Sample output:

/dev/scd0             3.5G  3.5G     0 100% /media/cdrom0

In this example, my CD / DVD device name is /dev/scd0 and mounted under /media/cdrom0. Now issue the following command as root user:
