How would you say that? No one will be demonstrating to you how to do it, especially that some details might be (read: are) well guarded company's secret (and top data recovery companies cooperate strictly with governments). But if you want an empiric proof you can get it. Overwrite some data *once* take your hdd and request recovery of that data from a reputable company. It will cost you some money, but you'll eventually get your data back. To make things easier for the company you can overwrite your data by zeros only (or by ones). The proof as such will still hold.


In 2003 the german computer magazine c't charged some recovery firms
(Ibas, Ontrack and Vogon) to restore a text file that had been
overwritten once with zeros.

None of the firms had been able to restore a single byte.

Recovery firms are very successful restoring data from crashed, burned,
watered harddisks but restoring overwritten data seems be left to
agencies which make the impossible possible... I don't belive that it's
possible on a modern harddisk.
