Wow this has turned a bit interesting hasn't it.
I think that the overall practical advice here (whilst keeping it simple) is - don't worry about it too much. Either wipe and re-install, or use a tool to wipe to a reasonable level.
People won't bother to try and recover your data, unless they think you have something that they might want.
Sorry for making the topic sound scary and overcomplicated. :-(
