Most people don't have access to that software because it just plain doesn't exist, it's nothing but BS! John

In the recently deceased TV show "24", the fictional CTU, the CounterTerrorism Unit, was frequently faced with computing resources (usually laptop or desktop hard drives) which had been intentionally or occasionally accidentally damaged before being captured from various terrorist organizations. Their software and particularly their personnel were legendary in being able to recover just enough data to carry on a complex confrontation with the baddies, but usually not close to enough data to achieve a decisive victory. They tended to do better as the end of each season approached, particularly once the always-present mole trying to advance the baddie cause in CTU headquarters had been detected.

You are the one who made the claim that there is some sort of 'magic' software available that can recover overwritten files, it is up to you to substantiate your claim and supply the name of the software and the company who makes this software. The leading forensic recovery software (EnCase) cannot do this and none of the major data recovery firms can do this, just call them and ask them and you will get the same answer from all of them. This idea that data could be recovered from overwritten drives was a theory advanced by Dr. Peter Gutmann and he himself has told me that his theory was misconstrued by many who read his paper, he was never able to recover overwritten files and he knows of no one who ever was.
