I've sent a message like this to the manufacturer about this subject, now I'm doing the same to Nintendo to see if where on the line is really the "fault." I'm near the point of frustration, and long story summed up, I bought a new External Hard Drive, recieved it today, sent some data to it, says it's not working, thought it was because Mario 3D World was in it, then screen goes black after re-do and shows another error stating that the device was removed or not recieving enough power, and every USB slot ends up the same result. Nintendo I need help once again and hopefully before June and I think you know why I say that. I wish I can discuss more on this right now, but I have to get ready for work now. So I'm literally going to copy and paste an ENTIRE post of what I said to "Seagate" about what I'm experiencing.
"Here's the run down in the most calm state I can be right now, which is not much at all. I bought one of your 1TB External Hard Drive for a gaming system, the Wii U. I got the hard drive today from Amazon, and after the format I tried sending files from the system to the Hard Drive, and then I get an error. I thought it was just a fluke, new item bound to happen. Then it happens a lot more, where I would get a black screen stating "the device is either removed or not recieving enough power." Which has to be B.S. because it's just one cord, a USB cord, how is it not recieving enough power? I plugged it in every USB slot, the result is the same. Works for 1 maybe 3 minutes then error code if not black screen with error code. And since I already sent a few files into the hard drive it's almost near impossible to get back. well it's possible, it's just time consuming, and as I'm typing this, I have less that 19 minutes till I have to go to work. I bought it off Amazon for $69.99 (Prime membership) and even with that, it's a lot of money and it's money that goes to something you expect to work when you get it. I'm nearing the verge of just sending this back and getting my money back and try someone elses External Hard Drive, but first I will be sending this thread to see maybe if I'm doing something wrong, or maybe this external hard drive that makes me want to incinerate it really has a problem that was recieved while being transported, either way, I'm frusterated and it would be amazing if this can be resolved before the end of June. I have my reasons why I need it done before then."
Maybe someone here may know something I don't, if so, great, I'll take anything, I'll see all if any responses after 9 (4 hours and 30 minutes) from now.
