You can also hire Mobile Shredding companies for top security for example [youtube.com...]

But seriously, for most people using a hard drive wiper software, then beating the drive with a hammer or drilling some holes through the platter will disable it enough.

Personally, when I need to dispose of old hard drives I first wipe them with a hard drive wiping software, then smash it with a hammer, sand the whole drive a bit, leave it in a jar of salt water for a few days then toss it in the trash.

If someone is still able to get data off the drive at that point they deserve to have it!
