Error: card removed. Can't play games

[Froggytilly]

For context: I use the same sd card for my switch and my 3ds.

So a while ago I downloaded a game for my switch and, it said I didnt have enough space to download it and after archiving a bunch of stuff and deleting my screenshots, I still didnt have enough space so I had to backup my sd card and move some stuff from it to my phone (I dont have a computer). Now I wanted to play some 3ds so I put everything back on my sd card but I can't play any of my games. They dont show up on the top screen and when I try to open them I get an error that says: The card was removed.
Please help

First, why are you using the same sd card on 2 different systems?
2nd, do you have the Nintendo 3DS folder on the root of the sdcard?
You might wanna test that sd card with h2testw to make sure it's not faulty or defective.
- Backup all your data before doing the test.
- Format it as FAT32 32kb clusters before and after the test.
- if it passes the test, put the Nintendo 3DS folder back along with the Luma3DS and GodMode9 files to your sd card, insert it and try again.
- if it doesn't pass the test, then your sd card is defective and you need to get a new replacement sd card!

You can get a 32 gb sd card for your 3ds pretty cheap
