3ds sd card problem

[Skysam]

Hello
I got a modded 3ds with all my games on the sd card and and even tho the sd card isn't old (max 1 year) it suddenly got corrupted and when i put it in my phone to check the folders everything went to a folder named "LOST.DR" so is there any way to get my games back i really wanna play with it since it's summer break

What games were on the card? Were they just CIAs? If so then you could just do you-know-what and get them back.

Also, you should test your SD card by following this guide: https://3ds.hacks.guide/h2testw-(windows)
If the test passes, then continue by formatting your SD: https://3ds.hacks.guide/formatting-sd-(windows)
If it fails, then you probably need to use another card.
