Secure Erase v4.0 looks great!
Already reviewed the more detailed info on this via the Secure Erase CMRR Protocols PDF, http://cmrr.ucsd.edu/people/Hughes/CmrrSecureEraseProtocols.pdf
A recollection of sorts on Peter Guttman's original paper 'Secure Deletion of Data from Magnetic and Solid-State Memory' at http://www.usenix.org/publications/library/proceedings/sec96/full_papers/gutmann/
and the hard-hitting NBER rebuttal 'Can Intelligence Agencies Read Overwritten Data? A response to Gutmann' at http://www.nber.org/sys-admin/overwritten-data-gutmann.html
Hope that the background on Secure Erase CMRR never receives the criticism NBER's Feenberg writes in the last two lines of the rebuttal :
Surveying all the references, I conclude that Gutmann's claim belongs in the category of urban legend.
Or it may be in the category of marketing hype. I note that it is being used to sell a software package called "The Annililator".
Other secure-erase projects/utilities are
- DBAN (= Darik's Boot and Nuke), http://sourceforge.net/projects/dban/
- srm (= secure removal), http://sourceforge.net/projects/srm
DBAN -- already on the Ultimate Boot CD -- was released this past February as version 2.0.0,, and srm was released this past July as version 1.2.9.
