Hacking [Question] Using WUPInstaller unsuccessfully results in unusuable space?

[Wolfy]

Awhile back I used WUPInstaller and it ended up giving an error, I didn't think much of it at the time, but now that I check Data Management to see that only 13GB of the 32GB is being used and yet it shows only 200~ MBs free.

1. Any way to fix this currently?
2. Would I need to format the Wii U?
3. If I did format the Wii U, what will I lose/have to redo?

Does Data Management not ask you if you'd like to delete the unfinished content, or something similar?

I've had that happen a few times now on my USB a few times and Data Management always asks if I want to remove the data, I hit OK, and all of the space is back.

It did for about 3 times I checked, and then I believe I installed more, after which it has not shown up since then.

So that "unused data deletion" offer is real? I though that could be something to do with the installation of titles under patched sysNAND, since I never had this issue while installing my backups directly on "pure" sysNAND.

It occurred before CFW was even a thing.

I heard about it before, just never had this issue "before CFW". In my mind, since it ocurred during CFW usage, I thought about the console wanting to delete "weird data" (everything installed under CFW).

Nah, it usually only comes up if WUPinstaller failed at some point during installation. It can happen on pure sysNAND and sigpatched sysNAND.

It's a pretty huge flaw in the Wii U's security, actually. IOSU almost never realizes that you illegitimately installed the content, instead just thinking that whoever owned the content removed their NNID from the console.

Yeah, that figures. I just couldn't accept this flaw by the time. Seems like my console will be busy for some hours hahaha, I never let it delete the weird data.

As you stated, WUPInst had this issue on pure sysNAND as well, and I even heard about it from other, but since I never got it before CFW, I had assumed that people were doing something wrong during the install process. I've even noted that my WUPInst had an error during the install of one title (mid install process, not before like when we have missing files, etc) and the console never argued about the parcial title installation, that led me to the wrong path of not considering the trash data deletion.

Way to fix it, as many time delete never works is to download a small demo file from the official eshop, once installed go back to data management and you should be able to delete the unnecessary data

So to clarify, the "delete unnecessary data" prompt in data management shouldn't delete anything thats been successfully installed? I get that sometimes and have said no in fear of it deleting my Brazilian games.

Yes.
I just did it yesterday.
All fakesigned and brazilian games untouched.

What the above guy said. I've never had my brazilian-method games, eShop titles, or even my NUSpacked games deleted by that process.

Perhaps someone will make a file system viewer of the general region so we can delete it manually, and I doubt it would brick because of that since it hasn't bricked just taking up space with nowhere to go.
