Re: Program to wipe data from disk free space

["Kurt Seifried" <[EMAIL PROTECTED]>]

Like most first attempt wiping programs this one fails miserably. It fails
to wipe slack space (i.e. 16k data allocations, a 10k file leaves 6k unused,
a previous file may have used it). It fails to wipe MFT space (small files
may be stored directly in the MFT). This would leave a TON of evidence. My
advice: Buy wiping software that actually works. I did some testing, the
commercial ones don't even fare to well, none of the amateur ones came even
close to being truly effective.
