IDNeon Posted November 21, 2017 Share Posted November 21, 2017 (edited) I don't know if I made a thread about this before, but this has always been a pet peeve of mine that I've never tested or built but kinda wish soooooommmmeonnneee else would (long lazy sigh). We all ought to know that Force Microscopy can be used to examine a disk at its atomic scale and basically rebuild data that has been overwritten. Therefore there's some debate as to how many "passes" are enough, and to whether or not degaussing is sufficient. And you can buy degaussers for such a purpose. I believe the evidence suggests degaussing is sufficient but we CAN GO FURTHER! I give to you the Induction Heater! https://youtu.be/VydPQuLyEns Behold! Aluminum being melted in about 1 minute. Imagine the FBI raiding your apt and you flip the switch and that puppy already installed around your external drives (or whatever set-up) turns on and just melts your harddrive. The first nano-second is going to blast the harddrive in a powerful alternating magnetic field anyway, but just to be sure. Ya know...melted slag in 1 minute tops. Hillary Clinton's Bleach Bit theoretically has nothing on this. In all seriousness though, induction heaters are easy to build, easier to buy, run on about 3kw, and will degauss AND physically destroy your harddrives at the same time. Not sure what its effect would be on a SSD other than that it would most certainly melt those too (if they are using any kind of metallic case). Induction heaters work on any metal as far as I am aware, magnetic properties of metals come from the ability to align all the magnetic fields in that metal, which non-magnetic metals are resistant to but are not themselves "without" magnetism. Induction heaters simply oscillate between polarities so that these fields are constantly shifting creating friction and thus heat. So would work on any substance that responds to magnetism, not just magnetic materials. Edited November 21, 2017 by IDNeon Quote Link to comment Share on other sites More sharing options...
