In the latter case you are correct. In the former case part or all of the sectors could have been re-used for other files. For the best chance at recovery, make your root partition read-only _now_. For future reference; you should never edit files in /etc/ directly. If you want ot edit files in /etc or /usr/local/etc, first copy them to a directory in your $HOME, put them under revision control and then edit them and copy = the edited files to /etc. That way you always have a backup and you can even restore previous versions.
