So, has anybody tried this? Any success?Do yourself a favor and use professional software that is also open source. Clonezilla clones anything.
Also, I'm worried about something. I have two identical 2.5" 500 GB drives (same brand, model, etc.). One full of games, one empty and unused. But those drives don't have any power connector. They are fueled only via USB. Which means they need a USB "y" cable each. Which means they need 4 USB ports total. The Wii U has 4 USB ports (2 front, 2 back). If I were to use the Wii U's copy feature, would it work with one hard drive on the 2 back ports and the other on the 2 front ports?
