Even with an MFM there is less than a 50% chance of getting it right so you'd be better off just using a coin and calling heads for one and tails for zero. One pass is enough.

Is the first software I have known to do this, CCleaner does not and neither does Cyberscrub. I agree with using JETICOs BCWIPE, unless you use speech software and need the temp files. Active@Killdisk Suite says something to the effect of even wiping the Sector 0, not sure about HPA or some of the other areas spoken of: have not tried Nuke and Boot although I have it for use. In an age with people keeping personal information on computers for medical or record purposes, it is great to see some lucid dialogue about data sanitization in lieu of Laws regarding various forms of personal Data (HIPAA, etc..) Nice article, thanks for posting. I use Active@Killdisk Suite for Windows v5.2; it has wipe options for file slack and will clean out the deleted entries in the MFT kept under ‘Lost and Found’.

Also, in doing some reading how would any of these programs handle the NTFS and the Master File Table? Would the entries still be there and recoverable? What about using Zilla Data Nuker?
