David,

In fact, the only thing I said is that "it has not yet been
*DEMONSTRATED* how to do it in more or less reliable way"......

I don't exlude the possibility that it may have *partly* been done by
some agency. This is why they still incinerate disks with secret data,
although they allow overwriting confidential one. After all, don't
forget about "bad sectors" that can be found on practically any disk -
although they are not accessible to the software, some data may still
be left over from the time when they were, and, at this point,
specially tuned hardware should not have any problem retrieving it.

However, the statement like " any good data recovery company can do it
if data has been overwritten only once" is just a gross
exagerration.......

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.
