You work fast, greytrev - well done.

Hopefully ver 2.1 will have an one pass option:

Multipass is mandatory on magnetic storage media due to the mechanical r/w head positioning fluctuations (very minor), thereby giving the possiblity for an expert to read residual information on the sides of the r/w tracks.

This is not the case with flash memory as there are no moving parts.

So multipass overwrites are superflucious IMHO -
that is, until I've been told otherwise :-)
