Not sure what happened to my memory card. I have a GT4 game save on it (along with other game saves), and it works fine. However, I wanted to reset from scratch as I just got the DFP. Went to System Browser to delete my GT4 data, only to find out that the PS2 says the card has corrupted data on it, and it locks up the PS2. I can't delete any files, always locks up when reading in the game saves. The card wasn't corrupted before playing GT4, and thats all that has been played since I got GT4. And no, I didn't pull out the card or shut down the PS2 while the little red memory card symbol was flashing on the screen. So my question, is there any way to reformat the memory card? Is there a way, using the PS2, to reformat the card? I sure can't find it!!!
