"Unable to identify CD-ROM format"

I'm trying to mount an iso cd image, but I do not succeed. Google doesn't give any answers either. Can you help me?

Here's what I've tried:

Code:

thrix:/home/daan# mount -t iso9660 -o loop /home/daan/cd.iso /mnt/iso
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

thrix:/home/daan# ls -l /mnt/iso
total 0
thrix:/home/daan# dmesg | tail

You're lucky. I read the thread but getting jumbled up machine code was all I was able to see from my usb hard drive after executing the command :/
