I'm not a security professional, but I noticed this kind of question
appearing on various list once in a while. Since every time there seems
to be a different answers, I was wondering: has there ever been proof of
recovering data (overwritten just once with zeroes or arbitrary values)
via software? I mean real recovery not just restoring one bit and
