Well for the wii u to ask for removing the unnecessary data, i conclude that this is when installing a game is unsuccessful to install with a error or cancel it.
A solution here that i saw for the error i had is to re-download the games, i have do this two times and i got still the same error. After that, i have tried to install both games which made a problem on a USB drive instead of my WD hard drive and the two games have finally installed. I tried after that to transferred the game already installed from my usb drive to the hard drive and I have an error. The hard disk has been disconnected or not sufficiently powered and must be powered with a Y cable.
YES Yes I know the y cable is recommended.. I do not have a Y cable yet for the disk because i just got it but i have ordered one the same day from ebay. I have over 30 games installed on my hard drive and it works all, except this two games, It was a little more difficult to determine the problem.
Hi, Instead of answer me this i would have preferred a little help from you, Know this i never write a post without having searched in a theard. I have no special symbols at all.
