hi ,
got this wii u running CBHC .
i had a 64 gb usb flash drive on which there are few games its connected at the back usb port .
now i want to add more storage so i have got a Toshiba 250 gb external HDD and connected it to the front usb ports with a Y cable .the system asked me to format it which i did .
when i turn the console on its shows booting inot CBHC and then sign on screen ,but after that there is a message on the game pad "please wait " and the bottom right corner the usb log and there is a white wheel circling on it .

1)can the wii u be connected with 2 HDD at one time ..one usb flashdrive and other usb HDD.
2)how much time it will take for the 250 gb HDD to sync ,there are no games on it . do i have to put games for it to sync ??
3)do i have to copy all the games from the 64 gb usb flash drive onto the 250 gb external HDD connected with y cable ,,,can i do it via the system management /data management..
4)how do i copy the games saves the level which the kids have played and saved .
any recommendations from you
thanks
