# sudo usermod -G cdrom 

is different to 

# sudo usermod -G cdrom 

Do you know your actual user name?

ls /home   should show you the usernames on your computer, and if
your the only user, it may not be too hard to determine your user

Still K3B gives these errors:
* cdrecord has no permission to open the device; and
* modify device settings in K3b to solve this problem.

Worse, I tried the above with .
Now su gives "Authentication failure".
And sudo says that my username "is not in the sudoers file.  This 
incident will be reported."!
