I recently had a USB harddrive failure on my Wii U, and I'm in the process of using a data recovery company (and it's not cheap). I've realised that I will have problems getting the retrieved data from my computer (Mac or PC) to the Wii U system memory, as the computer says that the media (usb memory stick or sd card in a USB adapter) is in a format it can't access (the format is the format the Wii U uses).
I can only think of using usb or sd card memory as a way of transferring the save data to the Wii U system memory, but I have this problem of the computer not understanding the formatting and therefore not being able to transfer the files to the usb stick/sd card.
Is there any other way I can transfer the save files, wifi or something, or some way of getting around the computer not liking the Wii U formatting? If I can't get my save files transferred I will lose 55 hours of MArio Kart 8 progress, and will have to start again!
