I have a project that involves scrapping 1,700 3.5” hard drives. I usually don’t deal with aluminum. What would the anodized aluminum cases be classified as at the scrap yard?
I also have access to a sand blaster and a crew of high school kids that are dying to use it. Would the scrap price be different if they were blasted clean?
All the drives are dated no later than 1992. Does anyone know what metal the drive platters are made of?
you can search this on the forum on what the platers are made of...its been said a few times nows and where to sell them.
Sand basting them should not make them worth more.
I will buy the hard drives from you at $0.90 for that much weight. each drive is a pound or a little over so thats a cash offer of $1,530.
AL is selling for around $0.70 or so.
I wish I could flip these drives. They belonged to a company that operates several internet server farms with about 300 servers per location. Their drive arrays reject about 50 drives a week. The drives probably could be repaired and re-certified, but they still contain client data and they don’t want to risk putting a repaired drive back into service. I have to scrap & certify that the drives are destroyed, and produce a weekly scrap report. I just picked these people up and if all goes well, they’ll give me everything they need to get rid of for free from now on.Quote:

The drives would not be repaired. That would be for scrap drives. But to make sure on your paper work you can damage the drives beyond use by hitting the back of each one on top of the motor. What this will do is "push" the motor onto the hard drive disks and bend them out of shape. Once they are bent there is no fixing them. The disk and the data are gone for ever.Quote:

It doesn't just bend them, it breaks them. The platters shatter really easy.Quote:

Mechanic, some hard drives did have platters made out of glass with a coating (I think it was platinum just like the aluminum platters)
Ive been informed by a refiner that there is no platinum on the platters, his exact words were "that is a myth".
There is platinum on the disc but a miniscule amount on each..Quote:

Per the research I've done, the film on hard drive platters contains platinum, for a 3.5" platter, there is about 1 gram of film, and the film will contain between 10% and 35% platinum (more platinum the newer the drive). so 10 platters would be 1 gram or more.
you can always sell the hard drives on ebay. i think thats what im gonna do when i get enough i dont have that many. i wish i could scrap more computers though.
