In this post, I told the tale of the compact flash card that failed at magic hour in the magic kingdom. Two commenters suggested I contact Lexar. I did, and the company exchanged the 8gb card. I paid only the cost of mailing the faulty card to Lexar. I received the new card yesterday, took 400 tiff images of my foot, and the card worked fine, despite the ugliness of my foot. Thanks to Lexar for making it right.
