Secure Data Disposal (SDD) is a Windows tool used to build IBM PC-DOS boot floppies for the purpose of wiping hard drives. Each boot floppy utilizes the Scrub3 DOS executable to facilitate securely disposing of data on a systems hard drive. SCRUB3 is indifferent with respect to the operating system on a hard drive. It will ensure that any critical data is permanently removed from a PC before it is disposed.
