No it’s not formatted. It came as is when I bought it and I have not done anything to it besides putting my microsd cards in it. And you are right, that disk under sdc is the SD card reader.
Crazy thing, this SD card reader was reading fine when I was using Pop Os (even though cosmic was hella buggy). Idk… I kinda find this freaking ridiculous that it cant read it when this is the default file manager.
but let me see if it’s labeled as exfat…
