I have a Micro Center 16gb USB drive that I'm using on my 4gb Xbox 360 Slim. The USB drive met the minimum requirements and formatted without a hitch. I transferred all of my files onto it and did not have any errors at all. I was using it today without any problems as well. When I came back from class and turned on my Xbox, it said "No profiles found." When I go to check the memory, the only option it gives me is to configure my USB drive. It won't let me see any of the files. I have tried it in several USB ports on both my Xbox and my roommate's Xbox. The same problem occurs every time. It seems like it has unformatted itself. I could easily recover my profile, but it's all of my game saves that I'm worried about. Is there any way to fix this?
