The file grub.cfg is re-written by update-grub, so your edits
disappear. If you then restore the altered file, update-grub's result
is lost. You are in effect fighting with yourself.
You might try unmounting and powering off your external drive before
doing update-grub. Then it won't see the drive and may not put it in
the config file.
