M.2 as removable device

[rizEzir]

Ghello,

Yesterday, I  had updated board's BIOS and reinstalled whole system.

Since then, my NVMe drive (on which my system is installed) shows up as a removable device

Any help would be great, ty

 

System specs:

MSI X370 GAMING PRO (Latest BIOS v. 4A)

G.Skill Ripjaws V 2x8GB

AMD Ryzen 7 1700 (overclocked to 3,5 GHz)

Samsung 960 Evo 250Gb

Interesting, usually see this happen with HDDs or 2.5' SSDs but M.2..

Some say its Windows installing bad drivers, others say its the BIOS handling the device like that.

 

What I can suggest is clicking on the drive in device manager and under the Policies tab, see if write caching is checked. and if anything in relation to optimizing for quick removal is unchecked. There isn't much else I can think of. Considering this is an M.2 drive it does not support hot-swapping which is a usual option to disable for normal HDD/SSDs under BIOS if this occurs.

Drive is set like on a screenshot.

 

Before reinstalling system and updating BIOS everything had been working just fine. Do you think that simply reinstalling system could solve that issue?
