True statements on all points, but the thing is, those tools are best used to retrieve valuable data from a dying card. When a card starts losing blocks that way, it typically gets progressively worse. SD cards are cheap enough, even in this economy, you can find them for around ten US dollars. You can
just use some good disk utilities to revive the card. You should
invest in a new one. I am not a commissioned salesperson.
