does anybody know what the disc inside a hard drive is made of? Is it worth anything? Or should I just take the board off and sell the rest as a boardless hard drive? Thanks for any advice.

Check the electronic section of this forum for some good reading. There are lots of answers to the questions you have there. If tearing them apart, you will eventually get enough platters to sell on E-bay as well as magnets.

I tear all my scrap drives completly apart great stress relief.

Compliments of Wiki;Platters are typically made using an aluminium or glass and ceramic substrate. In disk manufacturing, a thin coating is deposited on both sides of the substrate, mostly by a vacuum deposition process called magnetron sputtering. The coating has a complex layered structure consisting of various metallic (mostly non-magnetic) alloys[clarification needed] as underlayers, optimized for the control of the crystallographic orientation and the grain size of the actual magnetic media layer on top of them, i.e. the film storing the bits of information. On top of it a protective carbon-based overcoat is deposited in the same sputtering process. In post-processing a nanometer thin polymeric lubricant layer gets deposited on top of the sputtered structure by dipping the disk into a solvent solution, after which the disk is buffed by various processes[clarification needed] to eliminate small defects and verified by a special sensor on a flying head for absence of

most of the drive sells as cast aluminium. + some motor breakage.

so much for the platinum theory !
Well some newer HD's might have more platinum content than older ones:

How much that is salvagable tho, ...good question, ...that links says yield: unknown

VERY VERY little not worth refining. I have tried and have spoken with various pro refiners. The yield is so low it is not finacially smart to do. Hope that helps if not my advise talk with the pros.Originally Posted by Jvcr1

The platinum coating is only microns thick. There is no way currently to efficiently refine the platinum off the platters.
However, if anyone would like to try - I'm sure there are a lot of us that have stacks of them we'd be willing to sell you.

I'm selling mine as scrap alum. after shredding them. Also see post #3 in this link, it will shed a little more light on the question.However, if anyone would like to try - I'm sure there are a lot of us that have stacks of them we'd be willing to sell you.
