I was trying to burn a cd. I get all the way to where I add files to be burned. I go to pick a device and there are none there. I try to setup the device and then it tries to make the cange to /etc/fstab. This is where I get the above error.

Here is output from fstab:

proc /proc proc defaults 0 0

/dev/sda /mnt/sda auto noauto,users,exec 0 0

/dev/scd0 /mnt/auto/cdrom auto ro,noauto,user,exec 0 0

How do I get around this?
