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.
