Hacking No micro SD Cards Work in Wii U: Write Protected.

[Sonic Angel Knight]

So basically the sd card has a number of sectors on it in with your data is stored much in the way a CD has a number of tracks. The cluster size dictates how much info each sector hold so 64kb cluster size holds 64kb of data in each sector and 32gb holds 32gb of data. So a card formated to 64kb will load quicker as each sector holds more information and less sectors are being read by the wiiu.

Okay that's more detailed, so then why is there a option for it? If the 64k is clearly faster and more prefered, why woud options like 32 even exist in the first place?

Memory efficiency. 32k will save you space and on a big drive, that space can be pretty huge.

So the choice is 32 = saving memory and 64 = faster speeds, is that correct?

Yeah. It's a simple trade-off.

I'm formatting to 64kb cluster but still doesn't wnanna work. Isn't there a way to check if it is formatted to the cluser size, maybe it failed?

 

[Sonic Angel Knight]

I see, thank you for answering that.

That's odd, my 16 GB MicroSDHC Class 4 from Kingston works just fine.

(vWii Homebrew doesn't work though, rip)

Is my SD card port broke?

Me? I'm not an engineer. Dust the thing.

Don't you have another SD card to try? with that you can check if the WiiU port is damage or not for sure.
And when i say another SD card, i don't mean another adapter, i mean another SD card.

Silly me, wrong thread!

yeah, any normal SD cards work fine. Not micro SDs with adapters as they say it has a write protected error.

Then try what @Petraplexity said, cause seems that's being locked by putting it inside the port, it happened to me once with my old laptop.

And test your microSD and confirm if it´s real and has true 64 Gb.

i have stored up to 60gb before so it's real.

Jeez, it´s so weird... on other gadgets the card works fine, and normal SD works fine on your Wii U, right? The only solution I can see for it now is to try in the shop for a replace (SD vs mSD), it´s possible?

Try a small amount of tape over the whole write-protection switch area.
It might sound like a stupid idea, but it worked for me once. Might as well try it.

Thank you very much! It worked for me!

so this post is from 2016, hi im from the future. im trying to start the modding process for my wii u and im coming to the same issue. no matter what i try to do its all write protected. the first step where i move the "wiiu" folder into the root of my brand new 32gb FAT32 micro sd card, suddenly tells me that the wiiu folder is write protected. 9 years later does anyone have an answer for me?

low and behold i found my own solution. an old microsd adapter that i havent used since messing around with my n3dsLL... i used that one instead of this new one and it actually works just fine and allowed me to transfer over files.

Glad you solved it. For others (this is a common issue): What might also work is putting a piece of tape over the write lock switch.

And if that does help: As a last resort you can bridge the legs labeled WP1 and WP2 on the back of the SD slot together with a solder blob. That disables the write protect permanently and ignores the switch completely.
