Ok so me and one of my friends got a xk3y. He was wondering how to use a usb stick(flashdrive) So he kept messing around and got it to work ,But he has moved and never told me it and when i try to do it my flashdrive it says that any Non NTFS format does not support 4GB or larger pation(incorrect spelling but Forget it)But 1.) I Don't know what the xk3y reads I.E ( Fat32,exFat,NTFS,Etc). 2.) If it is a Fat of some sort my comp. don't format it as such and need to download a for matter but i don't know where one is When formated as These types of formats (Fat32,NTFS,Exfat) Fat32(default) - dont even get to the 360 stage due to the Patiton thingy NTFS - It reads my flashdrive as a mixed media disk exFat- Just keeps reading reading reading then tells me to open Tray I've got tons of games to play .but can't get it to work to play them .
