I plan on selling my PC but I want to delete everything off it before selling. I've tried researching the past couple of hours I'm getting turn around here. At first I saw something about using a program called Dban, but apparently that doesn't work on ssd's. So then I saw that my ssd (samsung 850 evo) has a secure erase function through the magician software. So I tried that but it didn't delete the OS. So what is the best way to delete as much as possible before selling my PC? My PC has a 1tb ssd 850 evo and a 1tb hdd, but the hdd was just used for game storage.
