What OS are you using? Is this your only disk drive?
Have you tried this:
http://www.yolinux.com/TUTORIALS/Lin...n.html#MOUNTCD
Mounting a CD: mount -r -t iso9660 /dev/cdrom /mnt/cdrom
Un-Mount the CD-ROM: umount /dev/cdrom (No "n" in umount)
This command should work for a Red Hat installation. Other distributions may require the following set-up:
ln -sf /dev/hdc /dev/scd0 Reference SCSI device directly.
OR
ln -sf /dev/hdc /dev/cdrom A more typical system
cd /mnt
mkdir cdrom
mount -t iso9660 -o ro /dev/cdrom /mnt/cdrom
