No, it's not about what you're thinking. In a new paper, Craig Wright, Dave Kleinman, and Shyaam Sundhar R. S. seek to debunk the notion that it takes more than a single overwrite to securely delete digital data. "We demonstrate that the controversy surrounding this topic is unfounded."
The paper represents a challenge to some of the arguments in Mechanisms regarding the permanence of digital inscription. In particular, the authors suggest that Peter Gutmann's method of multiple redundant data passes to "sanitize" magnetic media has had undue influence, introducing a mythology about the difficulty of effectively erasing information stored on a magnetic disk.
