I have just moved from Windows to Ubuntu. Before I uninstalled windows I put some documents that I needed on a CD. Once I had installed Ubuntu I put the CD in to get the files back. But all I get is the message...

Error mounting /dev/sr0 at /media/chris/UDF Volume: Command-line `mount -t "udf" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,iocharset=utf8,umask=0077" "/dev/sr0" "/media/chris/UDF Volume"' exited with non-zero exit status 32: 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

People are not going to migrate from windows if Ubuntu can't even do a simple task like open a CD without this meaningless error message.

Well as the error suggests, sometimes usefull info is found in the syslog. Can you open a terminal and post the output of: dmesg | tail here? – MrHug Feb 23 '13 at 17:56

Here is something you can try:


gksu gedit /etc/fstab

then add this code after the last line in fstab


/dev/sr0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0

tried but I get another error Error mounting: mount exited with exit code 1: helper failed with: mount: mount point /media/cdrom0 does not exist – mojo706 Jul 30 '13 at 12:19
/dev/sr0 /media/cdrom udf,iso9660 user,noauto,exec,utf8 0 0 – dr_smit Jan 23 at 13:54

try to make /media folder writable by

sudo chmod 777 /media

/dev/sr0 /media/cdrom udf,iso9660 user,noauto,exec,utf8 0 0

worked like magic as I had already existing /media/cdrom created by sudo mkdir /media/cdrom
