New member here, very informative site you have!
I have an IST DS that has me pulling my hair out. On our summer vacation I used a brand new Kingston 4gb memory card, formatted in the camera before any pictures taken. I shot over 1000 pictures on the card, but when I d'l the pictures, only about 500 are viewable. The rest show up as thumbnails, but there is no picture, while a few seem to have fragments of several pics. What went wrong? The camera reported "unable to display image", at which point I changed to another card.
I have tried to recover the pics with Sandisk ResuPro but no luck.
Any ideas?
