i've got a 128 mb card that i use when i know i'm only going to take a few pictures and i used it at wdw last week cause we were only there for 3 days. i was unable to retrieve 2 of my pictures from it-they uploaded, i just can't see them and when i took the memory card to wal-mart to get prints made, the pics didn't show up either. it's no big deal, i have others that hold more, but i didn't want to throw it away if it's still good. would reformatting the card correct the problem, or should i just toss it? TIA!
