There is NO truly secure method, other than complete pulverization, to destroy disk data. If you want to clear the free space and reuse it, then the methods described are sufficient. James McKenzie SSCP 367830 (Yes, I could give a real technical description of why but it involves a bunch of phyics and electrical stuff that usually drives folks nuts, suffice it that Data Discovery and Restore of Tucson can do what I describe to a hard drive that was trown into a fire and the heads were melted to the disk.
