Okay I'll start by saying the Wii U has been nothing but a pain in the A** for me since I got it.
I don't wanna bring everything up as it will take too long, but I wondered if someone could help me with my current issue.
I can play games off my external hard drive perfectly, but when I put a disc in the console, I'll click "launch game" for example I was wanting to play warriors orochi 3 hyper, so I clicked the little log of Yukimura and Zhao Yuns head and pressed play and up come a picture of them both and it said WARRIORS OROCHI 3, had a little wii u loading thing in the corner and the console was loading the disc, 5 seconds later everything STOPS!
It doesn't proceed any further, the music carries on playing, I can eject the disc and turn the gamepad off, the console itself freezes and the only way to turn that off is by unplugging it from the back.
I eventually bought the game anyway on the E shop as I was desperate for it and it works fine on my hard drive.
I've read online people saying their wii u's have come up "disc read error" but that isn't the case with mine
it just does nothing!
I tried unplugging the hard drive and loading it without, didn't work.
I just installed the newest update and thought it might fix it if it was a software issue, but straight after the update I restarted, put the disc in and again, nothing, just stays on the warriors orochi 3 hyper screen.
Any idea what this could be? Really don't fancy sending the console off 
If all games will be sold on the E shop I'm more then happy living without the disc drive, if nintendo give me some money.
So yeah, there's my question, thanks all 
Nintendo can't do that!
