Problem Description
The Eject Button on my CD/DVD/REV drive won't function on my Linux system, even though no automount programs are running.

Cause
Disabling of the drive eject button when media is inserted is common on Linux systems.
Solution
To see if the kernel is doing this, log in as root and type:

sysctl dev.cdrom.lock

If the response is "1", you can permanently change it to "0" with the following steps.

1) edit /etc/sysctl.conf and add the following two lines:
# Disable CD/DVD/REV eject button lock when media inserted

dev.cdrom.lock=0

2) Reboot the server to have the change take effect.
