uh yeah
my glitched 360 was slow and buggy with its fsd installed in her internal mem; thats the default installation for the guy who made it glitched for me
something happened and files were corrupted, no fsd running.... panic room mode !
i learned on forum how to made a usb flash key with fsd onto it, and voila, a fresh fsd :-)
so i made the same process to an external hdd, WD blue 320gb, and it runs faster as never seen, what a need for speed fsd
