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.
