Which still begs the question.  Who wrote that, and how do they know?  I mean, 
have they actually tested it, do they have equipment necessary to perform 
advanced data recovery, etc?

I actually think that the securest way to wipe data is to drill open the hard 
drive, grind the platters down to dust and then melt the entire thing in a 
blast furnace, but again, I haven't ever tested that method against data 
recovery methods, so I wouldn't want to say for sure.
