perhaps you need an entry in /etc/fstab like this;

$ sudo cat /etc/fstab

/dev/hdc /media/cdrom iso9660 rw,user,noauto 0 0

Note;
hda - 1st ATA/IDE device
hdb
hdc
hdd - 4th ATA/IDE device

To edit /etc/fstab - you'll use nano, or pico, or vim usually;
$ sudo nano /etc/fstab
move around using up/down arrows - make edits, save using CTRL-O -- press Enter when asked for filename ok - then CTRL-X to exit...(logout and then login - or reboot)

edited -- changed 'ro' to 'rw' (read only to read write)
