Hello,
I have a Wii U with an external HDD connected, with it's own power supply, and with a Y-cable usb attached. I've had this set-up since Wii U launch and have had no problems downloading games to it, transferring data, playing games, etc.
Today, I downloaded the Bayonetta 2 demo directly to my external (as this is where all my downloads go), walked away to make dinner, came back and saw an error saying that the external HDD lost power. I did a hard reset of my console, waited a bit, turned it back on and went to the download management. Bayonetta 2 demo had an error on it, suggesting I delete the corrupted file and redownload. I clicked delete, and about 30 seconds later, both screens went black. 10 seconds later the same error came up saying my external HDD lost power. In both instances, the external was still visibly running.
Did another hard reset, waited a couple minutes, turned the console back on and all it did was load the Wii U logo, nothing further (start-up sounds continued to loop). This is all that my Wii U does upon booting up with the external connected.
I have since removed the external HDD (with the console power off) and booted my console up without any issues. I went to the download management and "deleted" the corrupted Bayonetta 2 demo (though that file should still be on my external), and redownloaded the file just fine to my internal HDD. However, when I try to boot my console up with the external HDD connected, I get the same stagnant Wii U logo.
It's as if the Bayonetta 2 demo corrupted my external HDD.
What can I do?
(Sorry for the novel, just trying to be thorough with information)
