I'm trying to Homebrew my Nintendo Wii, and a 2 GB or under SD card is required. However, the Wii will also recognize 4 GB cards if enough junk is put on it. I'm attempting to do this with my Optima 4GB SD Card (goo.gl/qqJn8p) on Mac OS X, El Capitan (v. 10.11.6). After formatting it to ExFAT, I put a 1.28 GB file on the card. Everything went smoothly. The next time I tried, though, I got an error saying that there wasn't enough space, even though there's plenty left. Here's a screenshot of the SD card info.
I know that this is a common problem with USB's, but is there any solution for SD cards?
*As a sidenote, I formatted with Disk Utility.
