What is the function of the metal top cover on 2.5" HDDs? Do all models, regardless of brand, even older ones, have a metal top cover?

There is no such data publicly available. And there never has been. Contact the HDD manufacturers.
Please share their response on the forum.

I already contacted them, but they don't have a specialist HDD engineer to answer, only inexperienced chat support agents.
