Hardware I'm having constant reading errors with my 64GB SDXC Card.

[adrian2040]

These errors started a few days after I started using the card. The 3DS would say there is a reading error, either in-game or in the menu. This happens at least once or twice a day. It's a SanDisk card and I'm pretty sure it's a legit one.

Any help, please?

32 GB is the maximum limit for SDHC (SD High Capacity, utilize FAT32 format) cards, as 64 GB & higher are SDXC (SD eXtreme Capacity) that utilizes exFAT (aka FAT64) format which isn't supported by the 3DS at this time.

You can use any filesystem on SD(HC/XC) : EXT4, UDF and so on. FAT32 too.

The 3DS "supports" up to 32GB SDHC. So it may "work," but the possibilities of problems occurring isn't negligible, and I would just recommend using a 32GB one. Do you actually need the extra 32GB without having to transfer any files?

I'm having card issues my self, my card is 128GB, to use it with your 3DS it needs to be formatted to FAT32.
I used this:

Worked perfectly, but my read/write speeds are extremely slow which is pretty annoying (4 mb/s), I came to gbatemp to see if anyone other than me suffered the same issue and if there are any solutions. I can't Imagine how annoying will it be once I have 25 gb of games, would take 3 hours to copy.
