As stated above, my Horizon sees only 350mb space left on my hard drive.
It has 92.3gb free sapce, I want to install FIFA 15 to it, how come I see only 350mb free space left?
Because that isn’t your HDD, that is a flashdrive and at most xbox lets use some small amount like 16gb even if it is 500gb. You also can’t just install games using Horizon.
