The program I'm highlighting here is DBAN or (a.k.a.) Darik's Boot and Nuke. This
program is free and can be downloaded here. It downloads as an .ISO image for either a CD or a
DVD. This Program destroys data, permanently. So, Back-up, Back-up and then Back-up again. I have
used this program for very long time and it's become the de facto King of Hard Drive Wiping.
When I re-install any Operating System, I prep the Hard Disc with DBAN before doing so. After
burning the disc make sure the computer is set to boot from the CD\DVD Drive. This can be
accomplished through the BIOS or by selecting the "Boot Menu" F12 for most) at POST and
then choosing the drive where DBAN is located. Once DBAN boots you'll be presented with several
options, most having to do with becoming familiar with DBAN. To setup DBAN for a custom wipe, be it
the method or just selecting a drive, press the Enter key at this point. Now it is possible to
choose the Hard Drive, the method and various other settings before wiping data. Choosing the
"autonuke" command will erase all Data from all Hard Drives. The entire process can take
hours depending on the method and rounds, so don't get in a hurry. Also, if you forget to
back-up some data, like maybe your favorites, they are gone. That is extremely important to
The three methods I use are as follows: Quick (0-4 hrs.) + Med. Security = RCMP w\1 round; Normal (3-10 hrs.) + Med. Security = RCMP w\atleast 2 rounds; Hard Core (5-24 hrs.) + High security = PRNG w\4 or more rounds.
