I got a brand new ADATA 512Gb NVMe M.2 drive (ASX7000NP-512GT-C) and am using an ASRock AB350 Pro4 motherboard. I inserted the drive into the Ultra M.2 slot, until it clicked, and then screwed it down on the 2280 standoff. I tried booting with and without my SATA HDD, and both times it says that the M.2 slot is "not occupied" in BIOS. I tried turning on and off CSM and it didn't help. When booting into windows on my hard drive, it does not detect the empty drive in either Drive Manager or EaseUS Partition Manager. My motherboard is on the current 4.40 Firmware and the drive is warm to the touch so its getting power, just not being recognized?
