I work in healthcare, and this is a topic of discussion for us. We end up contracting to have them run through an industrial shredder, which, like nuking from space, is the only way to be sure!
We also do have a way to securely wipe them, but...it takes a long time and we only use it in very specific cases. For example, if we are selling expensive imaging hardware to another hospital, it can be very complicated because they also purchased the software that runs the scanner, so we can’t just completely wipe the disk, otherwise, they get an expensive piece of equipment that cannot run.
I have heard, though never tried it, that putting it in a microwave oven will destroy the data, though that may be urban legend.

The case will protect the platters inside ,, the microwave will however destroy the circuit board components on the outside of the drive. To be sure the platters must be physically destroyed or put through a secure erase procedure. The erase procedure takes a long time as it goes through multiple passes of every sector.
