X370 Taichi SATA issues

I have a brand new X370 Taichi with a Ryzen 1600 no overclocking. I update the bios to the latest version 3.20. I have a Samsung 960NvMe as the OS drive. I have been trying to get a second SATA drive to work properly since I built this thing. My first attempt was a Seagate 2.5 " drive. The performance was horrible so I ordered a new Western Digital Black 3.5" drive. Reinstalled with the user profile on the D drive. Everything seemed to go fine. I then just ran a whole computer AV scan and after a while, the machine locked up. I restarted and the WD drive was gone from the bios. I powered off the machine and started backed up. The WD was detected again. I pulled the WD drive and ran WD diagnostics on another PC. Smart Status was good, short test was good, ran the extended test and its good. Put the WD back in the machine and attempted to run the WD diagnostics on this build and I can see that as soon as I engage the quick test windows exlporer.exe crashes and MS onedrive as well. Basically, the D drive seems to be ejected. I reboot the WD drive is still present. The machine runs fine until I engage something that does heavy IO on the drive.  I also went back to that Seagate drive and ran crystal mark on a separate PC. The performance was exactly where I would have expected it. On the new build with the Seagate the read was fine but the write was half of what it was on the other PC.

What else have I done?

Tried a new SATA cable

Tried all the SATA ports except the ASmedia SATA Ports.

Ran chkdsk on the WD drive and no errors reported.

Updated to the AMD4 17.30 chipset drivers.

I researched this and someone else reported poor performance with a WD blue on this board as well, but nothing like this.

As far as I can tell the WD drive is fine. The original Seagate drive is fine as well.

I am about to reinstall for the 3rd time with an older Seagate 3.5" drive I have. Trying not to RMA the board here.

I could get the Chipset driver to update by manually updating and pointing it to the chipset driver folder. The CPU Ryzen controller no such luck.  Asrock doesn't even provide the Asmedia drivers, you have to go out to the web to get those and the sources are questionable, to say the least.

Anyway, I updated the chipset driver and moved my WD drive to SATA port 5. 

The same issue occurs. 

I do have an email into Asrock as well. However, my research points to definite problems with the AM4 SATA ports. You would never know that there is an issue if you didn't try to connect a SATA drive up. I may just end up RMA'ing both of the boards I have as this seems like an AM4 issue. Either go back to an Intel Build or perhaps a different AM4 board.

I will try with a different drive and see what happens.

For the record, I found the device ID's in another post on this board.

Maybe its some kind of weird Hard drive issue.
