Uh, so did you retry?"Initialising sd card failed! retry?" it said.
Any fix?
Make sure your memory card is formatted using FAT32, with 32k clusters. Windows formats larger memory cards using exFAT by default, which the 3DS doesn't support. So you'll need to use a third party application to get it done.Before starting, you may want to check your SD card for errors using H2testw (Windows), F3 (Linux), or F3X (Mac)!
All quotes are from The 3DS.guide
- Your SD card should be MBR, not GPT (the SD card that comes with the device will be MBR by default).
- If you need to format a brand new SD card, you can use guiformat and set to an Allocation Unit Size of 32K.
