Can't mount an ISO and the one time it did, it showed up empty.

iso is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/loop1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

dmesg | tail

Show us the commands you used leading up to this and is it just this ISO file or have you tried and failed with more? –  Deryck Feb 3 '14 at 3:51
    
What type of media are you trying to mount from your cdrom? ISO? –  Maythux Feb 3 '14 at 5:51

ISO 9660 Wikipedia's page

The ISO 13490 standard is an extension to the ISO 9660 format that adds support for multiple sessions on a disc. Since ISO 9660 is by design a read-only, pre-mastered file system, all the data has to be written in one go or "session" to the medium. Once written, there is no provision for altering the stored content. ISO 13490 was created to allow adding more files to a writeable disc such as CD-R in multiple sessions.

The conclusion: ISO9660 is a read-only filesystem. It can't be mounted in rw mode because there is no support for that in the filesystem itself.

I believe I figured it, the ISO is not in 9660 format so I'm using iat to convert it
