Ok, that answers my question. Usually I don't see thing from the same point of view than you, I mean, usually I think about "secure deletion" if the file can't be fully recovered by the use of a simple recovery tool (let's say, Norton unDelete)... but of course, in other context, fragments of information can be very dangerous and the attacker can bring the hdd to an specialized lab... In other words, if I intend to destroy the PhD thesis of my brother, overwritting 50% of it would be more than enough to make him cry like a baby. But if I intend to destroy the list of infiltrated agents of the Rebel Alliance, even a 5% of the list would make Darth Vader be really happy. To David Shaw: I didn't get your point, since both defragmenting and overwriting files involve to be able to control what is written and where is written... I think both concepts are related somehow. Anyway, I already got my answer.
