maybe my sd card is too small to format that big. its only 4 gigs........
O.o
That is an odd error
Not seen that before. I'll check mine again now. Hold on

Worked fine for me
=( welp. at least you tried. thanks.Out of ideas here. Maybe someone else can help you.
Sorry

Wow. I never exepected to see you here. Thanks, i'll try it nowYou can wipe it completely and then re-format with guiformat, but you'll lose all your files so BACK IT UP (or just move all the files off)
Start Menu, Command Prompt/cmd, right click and Run as Administrator
You might need to assign a letter if it doesn't show up in your File Explorer window, do
- diskpart
- list disk
- select disk # (based on the last thing and what it printed out, you said it's 4GB so find the one near that size)
- clean all (or just "clean", shouldn't throw an error)
- make partition primary
- select partition 1 (they start from 1 for some reason)
- format fs=fat32 quick (quick takes way less time)
Then it should show up in File Explorer and guiformat, then select it and run it with Quick and 4096 (if it's 4GB), if it says it's locked, either unplug it and replug it or go into Task Manager (start menu or Ctrl+Alt+Del menu) and kill Windows Explorer (should say "Restart" instead), and then go right to guiformat without reopening any of its windows and run it again
- list volume
- select volume # (same thing, should be ~4GB)
- assign letter=D (or whatever letter is available if you have other devices plugged in)
Note that this will restore any drive, if you have a hidden partition cause of emuNAND/redNAND, cleaning and then making a new partition as above will restore it to the original "size"

I had some trouble in the past when using diskpart with sd cards. The reader blinked forever and nothing happened.Wow. I never exepected to see you here. Thanks, i'll try it now

what do? i put make partition primary but it did nothing, just repeated the screen you get when its done clean all. also sorry for asking so many questions. i just wanna make sure nothing goes wrong and i think you can tell that im not a pro at this.

Sd card formater did the job always without any problems (at least for SD and SDHC cards)
@NWPlayer123 when will you stream again?
Edit: it's create partition primary - not make
Thanksinstead of make partition primary use
create partition primary
Ok, i've done all the steps you told me to do. now what?You can wipe it completely and then re-format with guiformat, but you'll lose all your files so BACK IT UP (or just move all the files off)

Ok, i've done all the steps you told me to do. now what?
Ok. but two questions. one: how do you know if the wiiu recognises the SD cardcopy your apps back on and try again

It will let you copy to SD in Mii Maker for a QR, that also supposedly fixes it, and doesn't matter the site, some will work others won't, depends on internet and some other stuffOk. but two questions. one: how do you know if the wiiu recognises the SD card
two: which browser exploit should i use.
