i really doubt that they can do anything about it
m2 nvme was not designed with hotplug in mind, unlike SATA
PCI express was designed as hot plugable in mind...thunderbolt is wired to CPU pcie lanes, meaning they can either enable/disable hotplug on CPU pcie lanes, not on device itself
so even your GPU is hot swapable now :D

its something that could be fixed inside operating system...say with chipset driver? which would change registry keys for CPU m2 slots to be internal]]> Fri, 22 Sep 2023 12:48:53 +0000 https://forum.asrock.com/forum_posts.asp?TID=25490&PID=107649&title=fix-x670e-taichi-m-2-appears-as-removable-device#107649 https://forum.asrock.com/forum_posts.asp?TID=25490&PID=107642&title=fix-x670e-taichi-m-2-appears-as-removable-device#107642 Author: SereneScream

Hello all,

I have seen a few people mention that they were experiencing what appeared to be a bug with the x670e Taichi board showing M.2 drives as removable devices in Windows.

The fix is simple. Disable Thunderbolt in BIOS and the M.2 drive in slot M2_1 will stop appearing as removable.

I originally reported this to ASRock support and credit to them as they provided me with the reason this was happening and the solution to resolve it, quoted below.

"Although not certified for Thunderbolt, this motherboard actually has an Intel USB4 Controller (Maple Ridge). We tied that controller to the CPU. Just like M2_1, Thunderbolt requires hot plug support.

Because both are tied to the CPU, we cannot disable hot plug for one and keep it enabled for the other. AM5 has no native support for Thunderbolt, and our creative solution comes with this minor downside."

I have tested this and confirmed it works and it doesn't outright disable the ports on the motherboard which is an ok compromise if you don't plan on using Thunderbolt capabilities. If you do use Thunderbolt then for now you just have to live with the drive appearing as removable and be careful not to eject the drive by accident.
