I got a 1TB 850 EVO and figured I could use power supply cables from my brother as I had lost mine. It did not boot and I figured out that different power supply's have different cables many times. So i ordered a cable for my model. I attempted to install with the new cables and the system booted but I cannot find the drive anywhere and disk manager or as an unknown device or anything. I tried two different sata ports as well. If you have any ideas please let me know.
