X370 Taichi SATA SSD goes missing

This happened to me a few times on the B350 Fatal1ty board I bought a few weeks ago - would reboot and discover that the MyDIgital BPX 240GB M.2 NVMe board in M.2 slot 1 was no longer visible in the BIOS.  If I'd power the computer down, wait a few seconds and power it back up I could see it again.

The 1 SSD goes missing when I power on the machine if it was powered off for more than 1 hour (overnight for example). It only detects it again when I remove the SATA power cable and reinsert it.  If the system was off for under 1 hour and I power it on again, it detects fine. I tried moving the SSD to another SATA port, tried the other SATA power connectors that are working fine with the HDD's and I still have the same issue. I moved the SSD to another system and it detects fine. If I put the SSD in a USB 3.0 enclosure, it detects fine.  Anyone know what can be causing this?

No mention of trying a different SATA data cable.

What SATA driver are you using? SATA mode setting is?

Is the SSD in an AMD or ASMedia SATA port? Your board has those two SATA chipsets.

Version of Windows you are using? How did you install drivers after the Windows installation?

That SSD is what model?

I have the same problem here using two crucial BX100 (actual firmware) drives at AHCI. Windows 10 64 bit (1703) is not installable and an installed windows (cloned from working HDD install) is not bootable on these drives connected to the AMD sata ports. The drives are missing in bios on every soft reset of the system.

The ports using asmedia chipset are working fine with these SSD drives!

Edit: My crucial MX100 is working fine on the AMD ports

I tried ports 1-8 (AMD), HDD's are working fine there so it's not ports or cables. SATA is in AHCI. Windows 10 64-bit. I just installed drivers for the NVME drives, didn't install for Mushkin Reactor drive. It also does the same for Samsung 840 EVO I tested. Randomly won't detect, but will detect again on a full shutdown and power on again. I don't think it's drivers because it doesn't detect in UEFI Bios, unless a full shutdown and power on again.

If you don't see a drive in the Storage Configuration screen, and all the physical connections seem fine, and it was detected in another PC, then something may be wrong. That the problem is intermittent, that makes it more difficult to diagnose.

The Mushkin Reactor and 840 EVO are both SATA SSDs, and either use the standard Microsoft Windows 10 AHCI driver, storahci, or if you ran the AMD All in One driver installer, the AMD AHCI driver. The ASMedia chipset will use either the MSoft storahci driver, or the ASMedia SATA driver, if you installed it.

I don't know if the following will help solve your drive detection issues, Ryzen is new to me, I've only had a Ryzen system running for about a week. That's an ASRock X370 Killer SLI/ac, AMD 1700X, 16 GB G.SKILL FlareX 3200 @ 2933, Samsung 960 EVO, three Samsung 830 SSDs, two in RAID 0. What you've said in your posts hints that this might help.

I'm not sure if your board's UEFI has these options, or what version you are using, I hope the latest 2.00 version. In the Advanced screen, do you see the AMD CBS screen?

If so, in that screen find the Promontory Common Options screen, and in there the PT SATA Configuration screen.

Two options in this screen, PT Aggressive SATA Device Sleep Port0 and Port1. Set both to Disabled.

In the AMD CBS screen, there is also the FCH Common Options screen. The FCH is the X370 chipset, which can support up to eight SATA III ports. It also has a SATA Configuration screen. Why there are both Promontory and FCH SATA screen options, I am not yet clear about. Both Promontory and FCH are terms for the X370 chipset.

Regardless, this SATA Configuration screen has Aggressive SATA Device Sleep options, again try disabling them.

Let us know what happens. I have these options disabled, and have not had the same problem with drive recognition like you do. I did have something happen to a Samsung 850 EVO, that completely disappeared after initializing it with the AMD RAID software. Nothing can see it, even after restarts of the PC. Another SSD connected to the same SATA port is working fine.
