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.
