Just spit balling, but it might be possible to flatten the platters out to recover some of the data, maybe even enough to piece together what was on there. The proper method for destruction is to wipe the drives, then shred them.
That I’m not sure, I know the premise is that data is read and written magnetically, which would lead me to believe there is some kind of ferrous metal in there somewhere, but I couldn’t tell you the actual composition of the platters.
With tearing apart drives over the years, 3.5" always used aluminum platters, while the 2.5" ones used glass. (With greater data density and higher speeds however, this may have changed)
I’m assuming this is actually to render an old drive inoperable, in case of sensitive contents?

Yes for spinny drives.
For SSDs, when you delete something TRIM + physics ensures it’s really really gone all the time
Please stop shredding SSDs that can go on to a 2nd life…
Indeed. I was only speaking to HDDs considering OP’s image meme.
Aren’t the discs made from a material that shatters like glass?

A quick google search resulted that the actual platter is a non magnetic material like glass which is covered in a magnetic coating
Interesting, thanks for that. So perhaps folding the drives like that may indeed shatter the platters.
In principle yes but I never managed to shatter or break a disc platter… But then I never had a sledgehammer
It depends.

Correct, and it uses magnets to render the disks unreadable. One of those devices services https://at-rack.co.uk/ LTT using it https://youtu.be/4dR5lbF5-wo
Yes.
Although disks are also legitimately shredded.
It makes the most awful sound.
Trust me, that data is very definitely not destroyed.
