I have an M.2 960 I was using as an external drive that I now want to use as my windows and main storage drive on my new PC. I can’t get the BIOS to recognize it in either slot on the motherboard. It also won’t recognize an SSD drive I tried. I’m assuming they’re formatted incorrectly or there is partitioning I need to do? How should I be setting them up on my Mac so that my PC will recognize them?

Thanks!
