When i am playing a game and save it often works but sometimes they disappear! once when i loaded Earthbound my saves were gone! when i was about to load a save state in mega man x it said "Error loading file" really i did nothing to the saves! then i put my sd card to my computer i was about to delete the saves but they where still there and wouldn't go away showing as 0kb. Then i reinserted my sd card into my computer and it said there where problems on my sd card and fixed it, my saves where gone this time but this kept happening to me! maybe "something" is corrupting the save files, has this ever happened to you?
