Hacking data management unnecessary data freeze

[SakuraStarbur57]

Hey guys my wii u is stuck on the data management deleting unnecessary data screen and has been for about 2 hours. Is there any way to fix this using iOSu or anything other than a system format?
Help is appreciated -nick

Try installing the game that failed again.
Try installing a small game then try data management again.

Download any demo game from the eshop then go to data management and it will delete the unnecessary data.

The same happened to me a while back, try installing what you did before, that failed, something must of failed on install. You may have tried to install dlc to HDD that failed due to wrong ticket etc.. download it again correctly and install via config tool, mine happened on Rednand trying to install Call of Duty Ghosts & Pikmin 3 DLC.. at the same time and they failed. I realized this issue when I clicked on delete and it was still deleting and going round the next morning, 7hrs. later I installed the same DLC's again correctly and it went away!

I just pulled the plug, rebooted, tried again. But seems pretty normal. Shouldnt be anything to worry about.

I know it's offtopic but where did you find Call of Duty Ghosts?

And I'm with the same problem, the thing is, the game that failed on the installation was Paper Mario, and now my HDD (160GB) is already full... The small game method will still work this way?
