Hacking Super Card MINI SD not working

[supermayo8a]

My supercard was working perfectly fine until I formatted the SD card. Now, everytime I put it in the Supercard it says "not find the SD Please turn off the GBA"
I'm guessing it has to do with the firmware, but I don't know how to install it and even how to find it.
I tried moving the SD around so it would make contact, but nothing. It seems odd because this just happened when I formatted

EDIT: I turned on while holding L+R and it says "Test SD/MMC, SD/MMC error, error code: 03"
My SC version is 1.85

What filesystem did you choose when you formatted the card? You need to use FAT, not NTFS or another type. That's the only thing I can think of, because you are already on the latest Supercard firmware version 1.85

As Dan said, it needs to be FAt, not NTFS or FAT32 file system. Also, the maximum siE of SD cards supported is 2GB. If you're using a micro sd to mini sd converter, try a different one.

I'm usign a 3GB card formatted on FAT

That might be the issue, as the slot-2 Supercards do not support anything higher than 2 GB. Try to get a hold of a 1 GB card if you can, just to be absolutely sure.
