To destroy a HD, just take the shiny disc inside and put it to a grinder, and grind it down to the metal ring. Easy (:
I never tried it, but I also heard microwaving it would work, not sure though.
But I was wondering something. Is re-writing something the same, or different, than if you were to simply delete something? As in, if you had 'bankinfo.wps', and created another file called 'bankinfo.wps', and then replaced the first 'bankinfo.wps' with the one you just created, is it the same as deleting it, or different?
Or what if you simply open 'bankinfo.wps' and delete all of the text, and save it? Is all of the history of the file saved in it internally somehow?
when DOS was still the dominant program operating windows....yes. Files were set locations for data, and rewriting it would ultimatly delete what was changed leaving the new information. NOW your computer tracks just about everything you do, so you can actually retrieve alot of info you recently deleted or rewrote.
Microwaving would destroy it if left in for long enough....also a very powerful magnet or electric current would do it also. Harddrives store info the same way cassette tapes do, they magnatize the media aligning the particles. That way a reading head can view the information, in the case of harddrives, it will read a 0 or 1 in each location on the disc.
