Aren't the discs made from a material that shatters like glass?

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.

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.

It depends.

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)
