    The disk is supposedly coated with platinum. Is it possible to recover said special metal, or does anyone buy these?
    Community Answer
    The amount of platinum is so low that it's not worth doing. You will get some platinum, but you will need to recycle lots of hard drives to get a decent quantity.

  • Question
    Other than the magnets, are there trace elements one can recycle or sell to companies? If so, which companies?
    Community Answer
    Curry's PC World and other electronics shops may take it and give you a small amount of money for it, depending on the quality. If not you could maybe sell it online, somewhere like eBay for example.

    Community Answer
    Recycling old computer hard drives is a responsible way to dispose of them and ensure that the valuable materials they contain are properly handled. Here's how: (1) Back up your data: Before recycling your old hard drive, it's essential to back up any important data you want to keep. You can transfer files to a new computer or an external storage device, or utilize cloud-based storage services. (2) Wipe the hard drive: It's crucial to erase all the data from your hard drive to protect your privacy. Simply deleting files or formatting the drive is not enough, as the data can still be recovered. You can use disk-wiping software.
