But he goes on to say: Looking at this from the other point of view, with the ever-increasing data density on disk platters and a corresponding reduction in feature size and use of exotic techniques to record data on the medium, it's unlikely that anything can be recovered from any recent drive except perhaps a single level via basic error-cancelling techniques. So even those few passes of random data are overkill. I just want to make sure that any given day that the police come take my functioning computers way that nothing can be recovered that I explicitly deleted.

Gutmann himself regards the continued use of his method as Voodoo Yes well. We lay people have only the best voodoo to go by. There are many things that I do with computers that can be called voodoo by virtue of the fact that I do them superstitiously. And if I don't happen to know the optimal patterns/passes to apply to a specific drive, then I'll do what was last known to be adequate until I hear otherwise. (As I have just now.)

And no I don't want to physically shred my drive in a running server.
