I have a question unrelated to the original question (and to Linux...): How does this "wear leveling" work if a card is mostly full? E.g., my typical situation is that I have a 512 MB card, but 450 MB of it is full (with pictures I don't want to erase), and I constantly reuse the empty space. Am I damaging my card, or does the card notice this and copies around blocks even when I never touch them? Or should I just ignore this whole issue, because even if I take pictures and remove them 1,000 times, this is nothing compared to the 100,000 number you mentioned?
