[PI] Disk Doctors Data Sanitizer v1.0.1

** Disk Doctors Data Sanitizer

- Disk Doctors Data Sanitizer work not only by unlinking a file but also specifically overwriting them with garbage data. For very high security installations, overwiting the file several times is advised. Many government institutions have specific disk wiping standards for file deletion. Particularly, the U.S. DoD specification 5220.22 standard says a file must be overwritten three times.
