I have a 2TB Samsung 860 Pro drive that shows in BIOS, or if i plug in as an external USB drive. But if i plug it on SATA it doesn't show up in disk management, device manager or anywhere. Really frustrating not sure what to do. Have tried it on 2 PCs and same on both.
Which version of Windows 10 are you on? You can find that by Right clicking Start>Left clicking System. As for your SSD, install Samsung's Magician app and see if it comes up there. Also, what BIOS version are you currently on for your motherboard? Make and model of your PSU and it's age?
