Regarding the previous post I was thinking how a hard disk could be destroyed. In the following video, hard drives being shredded with an industrial shredder. It seems there is no better way to destroy hard drives than this but I read in some articles that the types of HD shredders in this video are considered inferior ‘coz this machines don’t chew up the HD’s, they grind them to dust and those little bits at the end of the video can be reassembled!
