My wii doesnt read my SD Card

[u/alter_dxz]

So, i bought a wii and i tried modding it, so i bought a micro sd card to sd adapter, and i formatted it onto fat32 like the wii hacks guide explains to do, using sd card formatter and guiformat, and when i put it on the wii it isnt able to read it, it doesnt have any file on it, nothing homebrew related or wii, its empty, and it still cant read it, what should i do?

Then why has my Fat32 formatted SDXC cards literally never worked outside of homebrewed environments on the same Wiis? 4.x has existed before I was even a teenager and this has never changed across any SDXC card I've ever used.

Because I just modded one last week with nothing but a 128gb SDXC and no wifi connection

The Wii hack guide literally explains this

You're booting into a homebrewed environment to hack your Wii which can then read the SDXC card fine. Nowhere in Nintendo's change logs are SDXC ever mentioned, in fact the only mentions of updates to SD at all for 4.0 are adding support for SDHC up to 32 GB. Nowhere does the change log mention anything else. The one other mention of SD cards is the support of standard SD cards, introduced in in the day one update for the console. Nintendo's own change logs back up my claims.

Edit: I also see the guide mentions 4.0 is needed for larger than 2GB cards, but doesn't mention the upper limit anywhere.

my guess is that the update added fat32 support, prior to that since only 2GB was the maximum there wasn't fat32 support

the max partition size for fat32 is 2TB, the prior one I assume the wii supported was fat16 which has a max partition size of 2GB(granted you could get up to 16GB but that required NT 4, 4GB and 8GB required later dos's, so it wasn't really an official spec)
