I have a Kingston Elite Pro CompactFlash Card (4GB, 133x) Every now and when I turn on the camera, where it should say how many pictures I have left it says FOR and if I try to review my pictures it says "Card Needs to be formatted" It hasnt deleted any important pictures yet...but when It deleted my sunset pic from yesterday I got really mad. I dont take the CF card out, I only take it out to put it in the card reader and put the pictures on the computer....which after that I delete all the pictures and format the card. Oh, and I thought I might mentionthat when I put the pictures on the computor...sometimes not all the files transer...it tells me another program may be using the file.....and doesnt copy it. Does anyone know why it keeps hapening? Im going to Arizona for all of July and I dont want those shots getting deleted. Its happened 3 times total....and Im really getting annoyed at it.
