MicroSD card not working after resetting switch

[charred ether]

You initialize your Switch, didn't you?

The Switch has this weird feature of well,... using one single microSD card for each console.

It will not let you use the same card on multiple Switch console

the first time you use a card on a console, it will format that card and sorta "register" that card to that console

If you wipe the console, however, it will also reset this. So your card now become a "stranger" to this console.

You can still recover this but it's annoying to do. May I ask if you still want to recover the video/screenshot on this card?

Of course, the save data is stored on the Switch's internal memory

Hmm but it's strange

normally you can reuse the card after formatting it with the Switch

I guess you need to properly format it with a PC instead

follow the instructions below
