Just a thought.

Anyway all the HDDs I’ve opened and destroyed have had metal platters and this was not different… Metal plated glass does indeed sound rather dangerous so that would have been a good thing to point out in the original article. Also the motor has virtually no torgue at all, so when a load is applied the speed drops well below the specified.

Funny this gets linked now, it’s already over two years old :)

All you “not a hack” whiners, *this* is what a HAD comment is *supposed* to look like.

Man up you whinging HAD readers. If you die with a hard drive platter pinning your head to your workbench at least it will be an awesome death.

Since it has already a mounting and some screws I think it’s easy to build something around it

The plates are just there for a surface, which seeing there brittleness Id probably opt for installing actual metal plates cute from sheet as opposed to glass….

Posting something like this is stupid. Especially when you don’t even bother to mention that this is extremely dangerous. There are still many drives that use metal plated glass platters… the energy in a spinning platter could cause it to literally explode when misused.
Something like this would not have been posted a year ago. Yes, it may have a cool factor but that is heavily outweighed but the maiming factor.
Stupid h-a-d… unbeliveably stupid post.

Remember to wear those safety glasses.

As for safety, all the HDDs I’ve taken apart seem at least as sturdy as the cheap “dremels” I’ve owned… Plus, along with the suggested epoxy, some kind of mesh or cloth could be sandwiched between the platters for even more strength.

A slightly safer use would be as a buffing/polishing wheel.
