Issue persists with the M.2 not displaying properly.
Issue persists with the M.2 not displaying properly.
I have a ROG STRIX B450-F Gaming board, GTX 1650 Super, 16GB Corsair Vengeance, a 2 TB Seagate HDD and a Samsung 860 SSD. I recently swapped in a Ryzen 5 5500 CPU and added a Samsung 970 EVO Plus M.2. I’ve tried all the troubleshooting steps available, but nothing appears in BIOS or Disk Management. I’ve verified every BIOS setting, ensured the BIOS is current, and confirmed the M.2 should work with my board. All storage and boot configurations have been adjusted. Admin credentials are set, defaults restored. Despite my expertise, I still can’t resolve it. The odd part was that SATA ports 5 and 6 were disabled when the drive was inserted into M.2_1, contrary to the manual instructions. I’m used to fixing these kinds of problems, but after eight hours I’m stuck. Thanks everyone for your help—I’ve gained a lot about BIOS settings recently, mostly out of stress. I brought the new drive back to Micro Center and it functioned properly! I was among those who received a faulty M.2 unit.

Turn off compatibility support mode in the BIOS settings if it's enabled
Excessive USB devices might affect PCIe compatibility. Could this happen? On older boards like the A320, updates for newer processors often needed stripping support for specific PCIe devices, which could prevent recognition of things such as M.2 drives. For instance, an A320 with an M.2 and GPU might fail to boot after updating for a Ryzen 3600. Checking BIOS update notes shows gradual removal of PCIe device support across several revisions before the 3600 support was added. It’s unclear which revision caused the issue, but it likely wouldn’t work with that setup. Edited September 19, 2022 by An0maly_76 Updated, more info
I'd say "excessive" USB devices refer to having many connected peripherals at once, like your keyboard, mouse, charger, and headset. It's about managing the load so performance isn't affected.
It seems related to overall current, maybe connected through the PCIe power supply.
You can verify this by reviewing the BIOS updates and ensuring there are no entries related to Ryzen 5000 or M.2 slot support.
