RE: Program to wipe data from disk free space

["Rainer Gerhards" <[EMAIL PROTECTED]>]

Hi,

Thanks for your effort, which is appreciated. You should, however, be
aware that a single overwrite is not necessary to really delete
evidence. There is a federal standard (I don't remember the source :()
on how this should be done. I think it specifies you need to overwrite
each position at least seven times, each time with a different pattern.
Otherwise it is possible to recover the data with some advanced methods
(don't ask me which they are, maybe someone can step in?).
