Peter Trei shcreibt:
/Begin inclusion
However, a disk is not a perfect palimpest. Each overwrite 
will  probabalistically destroy some portion of the previous
data. Even if 90% where recoverable after a single
overwrite, less than 3% of the data is left after 36 
overwrites.
/end inclusion

I suspect that this reasoning is flawed.
ie if 90% is recoverable after the first overwrite,you can't then overwrite again and claim that only 0.9*0.9 is left.probably whatever makes it through the first few passes will stay through the rest :(
