So I hooked up my 1TB hard drive with the y-cable, formatted it, downloaded The Wonderful 101, and while that was downloading, I tried to queue up the Metroid Trilogy and Tropical Freeze as well, but it kept telling me there wasn't enough space on the hard drive, but it was defaulting to system memory for those games. Does anybody have any idea why this is?
I even waited for The Wonderful 101 to finish downloading, then made sure it was downloaded to the external hard drive, and it was. I'm able to access that drive in the data management screen and The Wonderful 101 boots up just fine, but I still can't download anything else to the external hard drive, because everything defaults to the console's hard drive, which has no more room on it.
Edit: Turns out the console won't let you download games anywhere but wherever the saves for those games already exist, so I had to go in and move the save files for Donkey Kong and Monster Hunter. The problem with the Metroid one though was that it was a physical copy, so the save was only available from the original Wii menu, and that didn't recognize an external hard drive, so I had to delete the save. That was probably for the better though. Starting off in the middle of Metroid Prime is a nightmare.
