So this is what a corrupt memory card looks like!

It’s like looking into the face of God:

those file sizes crack me up; it's only a 2GB card!
those file sizes crack me up; it's only a 2GB card!

Oh well, after copying the non-corrupt images and formatting the card, I was good to go. That is, until the “CHA” error popped up again.. Let’s hope my trusty little D70 isn’t going to die any time soon. :(
