It simply creates a file in (in root) as big as there is free space on the disk. This is fine provided the file have rubbish in it - but with XTG its all blank.... wash you disks then do and undelete from root and you will find a (usually large) file. Look at it - its all blank.... Because the data is all blank (zeros) an anomalie search would produce probably ALL of the data that was there originally..... I have a program (written by me) that writes pseudo-random mess to the disk for a specified number of times. I am also working on another program which clears any data that remians in the last clusters of a file (i.e. past the EOF point). DOS 7 will do this automoatically I'm told (haven't lood and the beta is too messy to bother with). Chris P.S. Sorry for extra spaces in the quoting... my comm prrogram is somewhat broken....

A simple easy-to-get file over-writer (around 5 times if I remember correctly) for DOS is tbdel.com, part of the TBAV (ThunderByte Anti Virus) SW package. Mats

What worries me about most of these PC "DoD" file erasers is that I am reliably informed that on at least one occasion, 11 generations of data have been recovered from a generic SCSI hard disk. It was a very unusual circumstance (suspicion of data leakage from a very high security site), but I find it difficult to take 5-pass programs very seriously. Ian.

The NSA has done the same thing with a tunneling electron microscope.
