Hello everyone. I have discovered what appears to be a bug with my Fatal1ty AB350 Gaming-ITX motherboard, running with a Ryzen R7 1600X.

Whenever I do a cold boot, my boot drive, an OCZ RD400 256GB, is detected, and the system boots perfectly. However, whenever I do a reboot, either via the physical reset button, or by rebooting within Windows 10(x64) itself, BIOS no longer recognizes the RD400. It simply isn't listed as a hard drive attached to the system within BIOS. 

It does reappear and boot properly if I shut the system down and do another cold boot, even if it's right after I shut it down (so likely no thermal issues).

I've checked and re-seated the drive, and updated the BIOS to the most recent beta BIOS, 4.51A. Unfortunately, still no luck, even though a prior BIOS version, 4.50, specifically listed "Improve M.2 SSD compatibility" as a fix.

Does anyone know if this is a confirmed issue, and if so, if it's on ASRock's radar? Alternatively, is there something in the BIOS that I might be missing that could be causing this?

Any help would be greatly appreciated! This is driving me mad!

(EDIT) Note that I have tried resetting the BIOS as well. Still no help.

I've tried updating the firmware on the RD400 SSD, but still no luck.

No one has seen anything like this?

I question that as according to OCZ there is no FW updates for the RD400.

You're right. Sorry. I mispoke. It's been a long day. 

Anyway, no, I updated/reinstalled the driver and OCZ utility, on the off chance it might have helped. However, I'm pretty sure it's not a Windows issue. It's likely an issue with the ASROCK board, or less likely, the Ryzen processor.

I have the same motherboard and the same rd400. And had the same problem.
