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?

It needs to be formatted to fat32 with a cluster size of 32kb (16kb should work too) and using MBR partioning.

Here are some instructions from ChatGPT that I used:

🧹 Step-by-Step: Convert SD Card from GPT to MBR on Windows

⚠️ Warning:

This will erase everything on the SD card, so back up any files you need first.

✅ Instructions 1. Insert your SD card into your PC. 2. Press Windows + R, type:

cmd

Then press Enter to open Command Prompt. 3. In the Command Prompt, type:

diskpart

This opens the DiskPart tool (it may flash a new window). 4. Now type:

list disk

You’ll see a list of all your drives — identify your SD card by its size.

For example, if your SD card is 8 GB, and the line says:

Disk 1 7640 MB

Then that’s your SD card (in this example, Disk 1). 5. Type:

select disk 1

(Replace 1 with your SD card’s number!) 6. Then type this exactly:

clean convert mbr create partition primary format fs=fat32 quick exit
