"Unable to identify CD-ROM format"

[Daan]

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:

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

check the output of the file command and post it to here

file cd.iso it will detect the file format.

Hi Iwanabeguru, thanks for helping out.

thrix:/home/daan/# file cd.iso
cd.iso: data
thrix:/home/daan/#

thats the problem it's not a cd.iso image file its only data in an img file

check this link and when you extract the data succesfully make a cdiso from it with mkisofs.
extract .img - Ubuntu Forums

man dd
man mkisofs

Thanks, that was very helpful.

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 :/
