Since there's a lot of counterfeit disks lately (external disks that claim to be normal 500GB/1TB/2TB/4TB but inside it's only 16GB flashdisk and heavy iron, or nvme but it's just small microsd plugged inside and covered with heatsink so people wont get suspicious, flashdisk/microsd claiming to be 128GB but apparently it's only 4GB/8GB with firmware hack), what's the proper way to check whether the device I bought is real or not?
