I'm missing the default game download location button.

You can do that but you will have a little problem...

External dispositive have only the format 32 GB (if you have a external hard drive whif 500 GB of space the xbox format and uses only 32GB!!!

If you still want to do that go to settings memory in the beginshows the space of dispositives if i reember right you have a option (i can´t remember in that screen or inside of memory you want make "principal")to config a dispositive to be the main memory.

I hope i help you and forgive my bad english it´s self learnerd.

I don't see any option for that I'm afraid

Question?

When you download anything that show the dispositives atached in your 360?(don´t spam A, when confirm your download or you can´t see that screen).

if you don´t have you can "force" that same way go to settings option go to memory in memory transfer manualy (game by game) the saves and contents from one dispositive to another you want!!!

I strong recomend to end your problems buy the MS hard drive 320 GB you will have a lots of space(some markets ofer a game inside the hd)and have over that problem.

You in this moments quests...why i am not use my external hd, because MS only disponibilize in external dispositives (all of them!!!)a space of 32GB (if you maintain the external that will be "particionate" in lots of number of "memorys" and you still have
the same problem!!!

Buy a MS hard drive and be happy(costs a little more than a "normal" PC dispositive of that category but saves you a lots of problems of space and compability!!!).

Updates can only be downloaded to the drive where the game is located.

So, even if you have the external set as the default download location, if your game is located internally that is where the update will go. You can't have a games and updates on different drives.

Strange issue

It sounds like it's only allowing the drive for media access, rather than games and apps.

Did you try (a) a different usb port (b) a different usb cable (c) formatting the drive whilst connected to the xbox, setting the drive as the default install location and then downloading the smallest game you own and see if that installs to the drive ?

I have 2 external drives, with my WD drive being set as default install location and games always download and install there by default. I'm also using an xbox one x, running on the "delta" insider preview dashboard.
