Title:
  I cannot mount a particular cd-rom normally

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  When I stick a particular cd into my computer, Ubuntu is not mounting
  it. (Most CDs work, not this one though.)

  If I try on the command line:
  chris@dellie-linux:~$ sudo mount -t iso9660 /dev/sr0 /home/chris/testing
  [sudo] password for chris:
  mount: block device /dev/sr0 is write-protected, mounting read-only
  mount: wrong fs type, bad option, bad superblock on /dev/sr0,
         missing codepage or helper program, or other error
         In some cases useful info is found in syslog - try
         dmesg | tail  or so

  same message with
  chris@dellie-linux:~$ sudo mount /dev/sr0 /home/chris/testing

  In the syslog
  May 12 22:34:18 dellie-linux kernel: [ 2237.212710] ISOFS: Unable to identify CD-ROM format.

  But the following works to mount the cd

  chris@dellie-linux:~$ sudo mount -o loop /dev/sr0 /home/chris/testing/
  [sudo] password for chris:
  chris@dellie-linux:~$ cd /home/chris/testing
  chris@dellie-linux:~/testing$ ls
  autorun.inf  garden.exe  garden.pdf  Lessons  Photos  readme.txt

  in the syslog:
  May 12 22:42:11 dellie-linux kernel: [ 2709.805765] ISO 9660 Extensions: Microsoft Joliet Level 1
  May 12 22:42:11 dellie-linux kernel: [ 2709.805987] ISOFS: changing to secondary root

  The cd mounts normally on another computer running osX and it says the
  cd's filesystem is Joliet.
