I just recently formatted my 2GB Memory stick for PSP, and now it's not working correctly. I cannot transfer anything onto the memory card via PSP or Memory stick adapter. When I use my PSP to try and transfer, it says the memory stick is full, and when I try and use my memory stick adapter (which works for my 32MB memory stick), it doesn't even detect. I used my 3.10 OE-A PSP to format my stick. The PSP says that I have 2GB of free space on the memory stick, and everytime I go to the memory stick's games or saved data utility, the PSP detects a crapload of corrupted data. However, when I plug it in and try to see these corrupted files, they don't appear (I have all my folder options set to show even hidden/system files) as if the memory card is empty. I don't know what the hell happened.
