Although it's not valuable in terms of scrap, I think it'd be very informative if you posted a followup where you try to isolate some of the components and base metals, sort of a before and after 'these metals are in a hard drive'.
Regardless, excellently fun video

Of course there is also this fun method of hard drive destruction <a href="https://www.youtube.com/watch?v=iFurvAEPmZg" rel="nofollow noopener" target="_blank">https://www.youtube.com/watch?v=iFurvAEPmZg</a> a.ka. my ring launcher.

Magnetic Degaussing usually works well, though you need a machine designed for it. There are also machines designed specifically for physically destroying them.. Check out Garner Products. I use them at work.

great info, I actually need to destroy a large quantity of hard drive platters I have removed from scrapped drives. I already recycled the boards, cases and head assemblies, but I didnt have a cheap way to securely destroy the platters other then physical destruction which is very time consuming
