apt-cdrom error

[xyon]

I have read the man pages for apt-cdrom and done some searches and reading on this but I'm not finding what I need.
I have zen 1.2.3 installed and working ok. I wanted to try and upgrade it with sid. Not the entire install just some problem areas. I downloaded an unofficial debian unstable cd from a public wifi place and burned it. It mounts fine and will even start to install but I'm not interested in installing it over zen. The point is I can mount the cd and cd to the files on it. However when I try to use apt-cdrom (which is suppose to add the cd to my sources.list) this is the results: [root@zen:/etc]# apt-cdrom add
Using CD-ROM mount point /cdrom/
Unmounting CD-ROM
Please insert a Disc in the drive and press enter
Mounting CD-ROM
E: Failed to mount the cdrom.
It doesn't matter if I include the actual mount point of the cdrom (/dev/hdc) or use (/cdrom1 which is the listing for the cdrom in the filesystem) I still get the same results.
I'm including the fstab that the zen installer generated and I'm currently using
proc /proc proc defaults 0 0
/dev/hda7 / ext2 defaults,acl,errors=remount-ro 0 1
/dev/hda5 none swap sw 0 0
/dev/hdd /cdrom0 iso9660 noauto,owner,ro 0 0
/dev/hdc /cdrom1 iso9660 noauto,owner,ro 0 0

hdd is the cdwriter hdc is the cdrom/dvd reader

try placing the cd in your /dev/hdd/cdrom0 drive, and type the command

apt-cdrom -a

apt-cdrom -a

Thanks for the reply. I should have included that I had tried that also. Doesn't work-same error output as apt-cdrom add. Whoops I didn't try the burner (hdd) why would I want to use that drive? I logged into Zen and tried that-no luck. I also tried apt-cdrom ident. I just keep getting that same error message

E: Failed to mount the cdrom.

Happy New Year 2 All!

First unmount the cd/dvd rom

sudo umount /dev/sr0

Then mount it into /media/apt/

sudo mount /dev/sr0 /media/apt/


Next run

sudo apt-cdrom add

I did the this and worked for me.
