sd card with arduino pro micro not detected on windows 10

Hello, I’m learning and using arduino pro micro with a micro sd card adapter. I can write file to sd with ArduinoIDE and read it also, but I can’t detect it on windows 10.
When I insert my arduino (with Micro sd module) with an USB adapter and I run on cmd the command “wmic volume get driveletter” it shows only C: and D: It is normal or not? Can you help me?
Thanks

Yes. The Arduino with SD card will NOT appear as a drive in Windows. Or any other operating system.

I am currently working on pluggable USB MSC device. In Linux I can mount and it reads/writes the SD FAT32.

It is quite slow and is not stable yet.

if you want to try, it is here: https://github.com/markmal/MSD but it is very rough yet.
