is it possible to plug in a second wii u hdd? what I'm wanting to do is transfer all of the games/saves from one hdd to another.

 

thanks. can u clone the entire hdd instead of moving one game at a time? also, will this affect redNAND if I'm using another hdd afterwards?

 

you can select more than one game to move to another hdd. there is an option to chose what you want to move, you can select all... and it will not affect the rednand, just do it in rednand .
