Seriously though, I haven't really seen an effective way, using technology, to really truly make a hard drive 100% unrecoverable.

Write zeroes? It like has fuckin magnetic residue or some shit and using the writing algorithm they can reconstruct the data or something.

To me, the classics never go out of style. Hammer, sandpaper, optional woodchipper, then fire. It's not too hard to get wood to burn blue.

tl;dr If it's a mound of slag I'm 100% certain it can't be recovered.

Rare-earth-metal magnets also help to truly scramble old electronics, just don't do it near stuff you want to keep.

We get the maintenance guys to drill through ours, or saw them into pieces and then bathe them in a corrosive bath.

You can degauss a hard drive. I've done it for work before. Just be sure to leave your watch or phone or something else valuable outside.

Degaussers are really fun. And if you're extra paranoid, Garner makes drive crushers that bend regular drives in half, two at a time, and there's an attachment for the press to punch a ton of holes all over an SSD to make sure the storage cells are obliterated.

And if you're still worried after degaussing and crushing/punching....well, there's always thermite.

A single pass of zeros is sufficient for just about any hard drive bigger than an early 80s 10mb ST-566 disk. Even at that time, an electron microscope was needed to guess what individual bits used to be prior to wiping, and that has a pretty high error rate.

There's no way anyone's recovering from a full zero wipe; and if you want, you can do a random wipe or a multiple pass wipe with a tool like DBAN, but it's probably unnecessary.
