So Media Go creates a Medio Go folder on any flash medium attached while the program is running. Obviously I don't need such a folder for my micro sd used for my DS. So, as I delete this folder it tells me there is an error and the folder is not an existing file type and so i hit skip and then BOOM! micro sd is corrupted and must be formatted. WTF! thank Gaming GOD, 2 weeks ago I started backing up my save files on my PC so I only lost about 2 days play on pokemon black, but white is my main save. I thought I'd just put that out there.
