lspci shows me these controllers:

03:00.1 SATA controller: Advanced Micro Devices, Inc. [AMD] Device 43b5 (rev 02)
20:00.0 SATA controller: ASMedia Technology Inc. ASM1062 Serial ATA Controller (rev 02)
2f:00.2 SATA controller: Advanced Micro Devices, Inc. [AMD] FCH SATA Controller [AHCI mode] (rev 51)


What exactly is the last one (FCH SATA Controller)? I connected the drive to the first SATA port, and according to device id, it's connected to the first in the list above:

03:00.1 SATA controller: Advanced Micro Devices, Inc. [AMD] Device 43b5

The second is that ASMedia chipset for the last two SATA ports. But I'm not sure what the third is.

Appreciate the condescending reply. I posted here because the OP's issue sounds very similar to mine on the K4.

Because it miraculously stopped working properly when I updated my BIOS. 

I'll just deal with it.

My drive is GPT, and the problem is with ASMedia controller and new firmware. When the drive is attached to it with CSM disabled, firmware doesn't the the drive at all.

But thanks for the suggestion, I'm switching all my drives to AMD controller ports, so it wouldn't affect me either way, but Asrock should probably still fix this bug.

shmerl, datonyb is correct, of course.  I recommend the ASMedia ports for devices like optical drives.  The AMD SATA ports are faster and have access to the RAID function.  Why are you switching around with CSM?  Typically it is needed to be Disabled when running a RAID.  Is your boot device initialized to GPT?  If not that may be why you cannot see it when CMS is disabled, not a bug.  Enjoy, John.

I managed to narrow down the problem.

Asrock X370 Taichi lists SATA connectors as:

SATA3_1
SATA3_2
...
SATA3_8
SATA3_A1
SATA3_A2


Apparently, A1-A2 are ports of the ASMedia chipset, while the rest are ports from the AMD chipset.

Here is what I see in lspci:

03:00.1 SATA controller: Advanced Micro Devices, Inc. [AMD] Device 43b5 (rev 02)
20:00.0 SATA controller: ASMedia Technology Inc. ASM1062 Serial ATA Controller (rev 02)
2f:00.2 SATA controller: Advanced Micro Devices, Inc. [AMD] FCH SATA Controller [AHCI mode] (rev 51)


My hard drive was connected to one of the ASMedia chipset ports (A1), and when CSM is disabled, firmware doesn't see the hard drive at all. It sees it when CSM is enabled.

When I connect the hard drive to AMD chipset ports, the hard drive is seen in both cases, and the problem doesn't come up. This definitely looks like a bug to me.

And on a side note, which chipset is better to use for the primary hard drive? Is any of them performing better?

After much trial and error I can also confirm odd behavior with CSM (albeit on the K4 Gaming).

On v3.40, my machine booted and worked completely fine with CSM disabled.

Since updating to 4.50, I have to boot with CSM enabled otherwise my machine hangs during post (Dr Debug code 0E).

Yeah, during that long pause I see an underscore cursor on the screen for a while. Except for me it goes back into the setup UI instead of booting.
