I want to fix permissions on another disk with chown. Set the permissions to a user which does not exist on the system which is currently running.

Does that work without adding the user?

Use the numerical UID/GID instead of the user/group name.

You can find the UID/GID on the system the disk belongs to by using

  id some_username

or

ls -ln some_file

where some_file is a file that belongs to user you are looking for
