Hello Friends,
Today i am sharing one howto about how to block or disable CD/DVD ROM in Linux.
Below procedure is working fine on RHEL ( Red Hat Enterprise Linux 5).
1) You need to be root user to perform steps.
[blog@ask4it]$ su -
2) Go to Directory Where your kernel drivers stored. Follow exact command.
[root@ask4it]# cd /lib/modules/$(uname -r)/kernel/drivers/cdrom
3) Now list directory.
[root@ask4it cdrom]# ls
cdrom.ko
4) Now rename or delete cdrom.ko file with following command.
[root@ask4it cdrom]# mv cdrom.ko cdrom.ko-ok
To Delete file execute below command
[root@ask4it cdrom]# rm -rf cdrom.ko
5) Now reboot your computer and Insert CD or DVD into Drive. It will not detect.
6) If you dont want to reboot your computer then just execute below command.
modprobe -r sr_mod
Hope this helps you

Yes, You are right, both way can work, This is not a bad option. Not every end users knows about modules and all that. and in some premises we need to block from root also. That’s why this is howto is published. And Administrations can easily revert it back.

June 23, 2010 7:38 am nitins Yes root also, but root can easily enable it by moving back.This may not be an ideal solution, but it is okay in my case. June 23, 2010 8:48 am unixbhaskar This is an worst possible solution(above solution).I think people need to look into their /etc/fstab file for that kind of manipulation.If they take out “nouser” option from the cdrom/dvd line in /etc/fstab file then the desired result can be achieved .Moving out and in modules like that is a bad very bad option.
