Q:

SD Card Problems

When I try to put my SD card into my 3DS it gives me a pop up saying that it can’t detect a SD card. I tried reformatting it into FAT32 but it says it cant do a full long formatting and a quick on just gives the same error. I don’t know what to do and at this point i’m just gonna buy a nee SD card. Anyone have any ideas on whats wrong with it?

You can try the SD Formatter once, but don’t spend too long on it. Replacing it is the right move at this point

That situation usually points to either a corrupted card or a failing one- and given that formatting is failing, there’s a decent chance the card is dying.

Put the SD into your computer and backup the contents if possible. I’m assuming your sd card is dying and needs to be replaced

What brand is your ad card and what are you using to format it?

Also how large is the SD card? Aren’t there restrictions with using FAT32 and how large the card can be before you format it?

I think the card is probably dead, just buy a new one. Make sure it’s one from a reputable brand.
