Thanks for the excellent explanation :) One nitpick. You say "On a traditional hard drive, that will overwrite the original private information" but that's not quite true. It also needs to be a "traditional" file system! That is, not journalled or COW. So nowadays I would expect shred not to work unless you got very lucky, or planned carefully.
