When I worked in the Army, the procedures for data destruction varied by classification of the information. For the top items, the rule was as follows - hard drives has to be dismantled, and the platters cut or ground until all particles are smaller than "x" millimeters in size (I don't remember the size), then the particles has to be burnt, with some specified temperature (which I cn't remember now) - tape has to be burnt, also with a specified temperature Needless to say, we cooperated with the munitions department, which regularly burnt old ammo. At 1200 degrees centigrade we were well inside the specified temperature. -- Regards, Torfinn Ingolfsen, Norway
