I've heard the platters are platinum. I salvage the magnets out of them and scrap the rest as aluminum and tin. I appreciate any and all input....thanks!

The platters are *platinum plated* There is a buyer on the forum who buys them.Quote:

Much has been written on this subject, if you look at the bottom of each thread there is a list of related threads. Mike.
Here you go, the motors can be sold as alum. or as a motor. The bottom cases are cast alum. The top is alum sheet, or SS or sometime alum with a steel plate glued on. You will get the rare top that is plain steel.Quote:

Glad you mentioned both. At my yard they pay more for old sheet aluminum than for motors, so I just leave them on.Quote:

i have read quite a few write ups on the tear down of an HDD. However, I never see anyone talking about the small gold plated bit inside the actual read eye in all HDD's. I have found this same small gold plated part in every type of disk reader, ETC ... CD drives, DVD Drives, Blu-Ray and HDD's.
So my question is... Is there anyone else out there that collects these for a later sale.
It would take a loong time to save up enough of them to scrap them or sell them. Time is something I have a lot of. So I break everything down to the smallest parts that I can.

This is a breakdown I did last year.
Electron.....I've wondered about those and the gold appearing flat wires that go to them. If it's plated it would take forever to get enough to do anything. If solid, it could be worth saving. I hope someone lets us know what they actually are.
I have been saving bushels of the "arms" but I've yet to see any gold plating in a HD, could you enlighten me with a pic. please.Quote:

The mylar on the "arms" might have gold plating in spots. I think I have see gold rings around screw holes on various random mylars too.Quote:

It's taken me just about forever, but I've finally found some way to answer the simple question "How much platinum is in these hard drive platters showing up on Ebay for salvage?" "The Chemistry of Computing" over at extremetech.com (article2/0,2845,1946290,00.asp) has all the facts: surface layer of Co-Cr-Pt alloy is 40-50% platinum, and the layer is ~30 nm thick. I don't have a hard drive platter in front of me, so let's just forget about the hole in the middle for a moment, so one platter from a 3.5" disk is 3.14*(3.5/2)^2=10.4 sq inches or 67.2 cm^2 ... times the 30 nm thickness (3x10^-6 cm) is 2.0x10-4 cm^3, times the (optimistic) 50% Pd, times the density of Pt (21.45 g/cm^3) and I estimate one platter has at most 2.2 mg Pt. As of 08/29/2008, the platinum spot price was 1470.00 USD per troy ounce, or more usefully, 4.73 cents per miligram. So, congratulations, you've just spent an hour of time and three cents of chemicals (just a guess, probably high) to reclaim 10 cents of platinum, probably still contaminated with cobalt and chromium depending on your recovery method. I hope you bought a whole bunch of platters cheap and rode a bike to pick them up because I doubt you'll be paying for gas let alone the shipping with the platinum. Or hope those early hard drives used a much thicker layer....
Hard drives malfunction for a number of reasons. Hard drives are available in 2 sizes primarily. For personal computers they are 3.5” in size and for laptop computers they are 2.5” in size. The hard drive and dvd or cdrom drives in computers combined with the fans are the only mechanical pieces of equipment in a PC.

Everyone who is wondering about the platinum in harddrives please read Mechanics post above. The most knowledgeable refiners will all tell you that you will lose money trying to have the platters refined for platinum. Time,chemicals and labor costs will eat up any values recovered. Sell them for aluminum, stainless or sell them to a buyer here. You will come out way ahead that way. Use your time better pulling pins or cutting fingers it is more profitable.
