I connected my 4GB flash drive to my console and followed the instructions. It passed the test, and I was able to put game saves on the memory stick. After turning my system off, I later turned it back on and it wanted me to format my USB flash drive again, meaning my game saves that I previously put on there were somehow deleted. I didn't remove the flash drive before/after turning the system off. It has just been sitting in the USB port. Why did this happen? How can I fix this, it happens every time I turn off my system with/without the flash drive attached. Please help.
