First of all u have to get the driver of your CD or DVD
You can get it as follows:
[[email protected] ~]# eject -n
eject: device is `/dev/hdc'
The device driver is /dev/hdc
Now mount the cdrom
#mount /dev/hdc /mnt/cdrom
Note: create this directory 'cdrom' if in case it doesn't exist
You should see the list of files now.
And in case u want to use this command as a shortcut
#ln -s /dev/hdc /mnt/cdrom
