I have a 256MB orange scan disk pro duo memory stick for my psp and when it was loading a game twisted metal head on. On the loading screen my brother took the memory stick out of the port and my psp will not play it or even read it. Ive tryed the memory stick in several psps and none of them would read it. Is it broken or can I fix it. I bought it from a friend, but is there any place i can take it back to.
