Sorry if this is in the wrong thread, wasn't sure where it belonged. We have a Sony CyberShot camera that stores its images on a 128MB Memory Stick card. The problem is whenever we delete photos from the card after plugging it into a card reader, the available space doesn't increase like it should. Even if we delete everything from the card, it still shows the same remaining capacity. The only way we have found to get our space back is to move everything off the card onto one of our computers and run Memory Stick formatting software. We used to be able to simply delete the pictures and re-use the space for other things. What happened?
