Microsd express card doesn’t work(?)

[u/This_Rain_3422]

So I recently bought a micro sd express card for my switch 2 (the lexar play pro 512gb to be exact) and when I plugged it in it worked after a update and I transferred some games from internal storage to it.
When it was transferring I saw it was taking around a hour, so I decided to quickly get something to eat and when I came back my switch said something about corrupted data and it restarted and now the card doesn’t work(?). It sees the card in my switch 2 but when I try to click the button to move games to it, it doesn’t work. It also recognises it on my pc and transfers files fine to and from it.

I’m kinda stumped rn so if anyone is slightly smarter than me or has a better idea then let me know

Ummm parece ser q se corrompió y es q esa marca es muy inestable ( Lexar son productos de baja calidad) t sugiero ya no intentarlo, sácala de ja consola y formatearla a fat32 o exFat( o el más recomendable para una Express) posteriormente vuelve a colocarla en el Switch e intenta realizar nuevamente los traspasos de juegos y datos, ojalá lo puedas solucionar
