My officially licensed Sandisk 128gb microSDXC card has became full so I needed to upgrade. I put all the data onto my Mac. I then got my Sandisk Ultra 256gb microSDXC and put it onto my switch to format it. After that, I transferred all the data from my Mac onto my 256gb microSD card. When I put the 256gb sd card in the switch, it says that it is unable to access the microSD card. I’ve tried restarting the system and putting it back in but to no avail.

He might actually be right since I found an old Reddit guide on macOS

Actually, he’s not. You can’t transfer data between SD cards like that with the Switch.

#

Try formatting the SD card inside the switch, then downloading your games from the eshop

#

what about everything on my old sd card?

bold kraken
#

It won’t work on the new SD card.

jovial belfry
#

why not? I thought you could just transfer the Nintendo folder form one sd card to another

bold kraken
#

Nope. The data is cryptographically signed and the key is unique to each card.

jovial belfry
#

Huh

#

Wait so what about my save data?

bold kraken
#

Your save data is stored on the console, not the card

jovial belfry
#

Ah, I see

#

so everything on the card is just the game files

bold kraken
#

Yep

jovial belfry
#

I’ll just redownload them all

#

Ok gotcha

#

thanks

bold kraken
#

Any time

#

my switch was able to read my new card prior to transferring my data though

You will need a PC computer and a microSD card reader.
1. Use this software, SD Association's SD Memory Card Formatter, and format the microSD card using Overwrite option.

I can just format using my switch right

bold kraken
#

Yeah give that a go first

jovial belfry
#

yeah I did it a while ago and it worked but once I added the data from my old sd card it stopped working

#

Anyway now the switch is reading my new empty 256 sd card
