Just about a year ago I had a SanDisk CF card fail. I mailed it back to SanDisk but did not have the receipt to show date of purchase. Yesterday, a year later, I received a replacement card and a copy of their Rescue Pro software. I had registered the card on their web site and thus had life time protect. The moral of the story is if you are using SanDisk take the time to register. Les Only the paranoid survive.
