What is a rock-hard drive made of?

at work (in IT) we sometimes enjoy to destroy knotty drives - but they're made out of loads of things, including metal etc - so what are they made of, and are the metal parts any good for recycling/reusing?

What is a rock-hard drive made of?

The outer shell/case is aluminum.I recycle tough drives for about 35 cents a pound.They shred them and use a magnet to extract the metal disappearing the aluminum.I also recycle curcuit boards for 40 cents low grade 1.40 large grade.There is no section of a computer that cannot be recycled and reused.
Some people come up with that the platers that are in the strong drive are made of glass. The truth is that the platers are made of a metallic matter that is magnetized.
You can see the inside of a easier said than done drive with this cooperation:

The only motivation for destroying hard drives that I can deliberate of is to destroy the notes on the platters. This would be necessary if the strong drive is busted and you can't erase the sectors next to a program.

As for recycling, there's nought to really recycle. Stripping the metal would be far too costly & time consuming, and you can't really recycle circuit boards. Burning them wouldn't be a good concept because of the plasic, epoxy, fibreglass, and the lead-based solder. That's one of the problems that we have today - too much electronic second-hand goods.
they are made of loads of things including metal.
Although small they are made of a special material that have a built in calculator inside. the calculator can solitary add up 1s and 0s hence the small size.



Be measured when destroying because some of the little people inside who own to operate the calculator may get hurt. (these are matching people Willy Wonks employs)
