I got a weird problem when trying to run games through xexloader, freestyle etc. while 360 native hdd (20gb) is connected.
e.g. Fifa11, Red Dead Redemption. The games wont start, just a 360 cant read disc message pops up....When i disconnect the HDD the games just run fine when being started via Xex.
I tried cleaning the System Cache, Formatted the HDD via NXE. I got XBR 8955.
thx in advance
