HABClean 1.0

Destroy and Scrubber, that are designed to remove all traces of sensitive files The HABClean software package will include two easy to use utilities, Destroy and Scrubber, that are designed to remove all traces of sensitive files from hard or floppy disks before you pass them on to someone else.
While they are not intended to defeat the efforts of data-recovery professionals, they will make it very difficult for anyone to recover data from disks on which they have been used. Thus, unless you have very valuable data on your disks, the cost of recovery will be much greater than the value of the data to someone else.
Destroy - destroys files by blanking and then deleting them. When you use Destroy, you will be asked to choose the number of passes Destroy will use. If you choose more than one pass, all but the final pass overwrite the file with nonsense data. The final pass overwrites the file with null characters. Finally, Destroy renames the file to a meaningless single-letter name and then deletes it.
Scrubber removes traces of files previously deleted from the disk.
When you use Scrubber, you will be asked to choose the number of passes Scrubber will use. If you choose more than one pass, all but the final pass overwrite the unused portions of the disk with nonsense data. The final pass overwrites these portions with null characters. Thus no-one will be able to undelete previously deleted files.
