Re: A new use for Linux

A straight magnet can mess it up a bit, but I don't know about total
erasure.  Generally degaussing takes an AC field, such as that from the
degausing strip around a TV set or monitor (you degause tube type
monitors and tv's to keep the color guns from being biased and giving
fringes around the images).  And a hard disk drive is "saturation" type
recording, and some of the new ones use a very deep form of recording
that is different from the surface recording done on magnetic tape.  So
if you wish to degauss a drive (remove all forms of data including
formatting and bad sector stuff), then a very high strength degaussing
platform is needed.  Or a 5 lb or heavier hammer applied with gusto to
the platters seems to do a pretty thorough job, unless you are
discussing state secrets or the next advent of computing.

Or use that hammer to drive a small steel punch all the way through the drive. It's quick and someone would have to be pretty determined to get any data back after that.
