I usually just disassemble drives down to their component bits then toss individual platters into different dumpsters I stop at on my way to or from work. However I don't have anything worth recovering on the drives.
With multiplatter drives once you snap the spindle loose recovery is very difficult, typically it requires tools that were only available in the factory at the time that particular model was in production to put the platters back into alignment.
If its a single platter drive you could always drill a bunch of holes into the platter. Can't recover data from dust.
A zero wipe of the entire drive is generally sufficient from everyone outside of TLAs. TLAs are going to try and reconstruct your anime collection by reading from the periphery of the tracks where the write head doesn't normally reach. It tends to result in a very fragmented incomplete recovery. Perpendicular recording has made a lot of the older methods obsolete, like electron microscopy.
Combine zero wipe and drilling and disassembly and sprinkling parts across a city's dumpsters and you've made some TLA drones very sad and grumpy.
