does this mean I have to format the card everytime I transfer my photos??
I never realised I have this issue earlier. Normally I use my mac Aperture to transfer my photos then message pop up and ask whether delete images then eject card, which I normally click YES.
But most of the time, I just jack in the card, copy images to desktop and delete direct from the folder then eject and slot back to my camera.
Ah, you're a Mac user, just like me so I think I may have the answer. When you say "delete direct from the folder" did you just drag them to the trash without emptying? If so, this would explain it since the Mac OS will create a .Trash folder on the SD card until you empty the trash. Once you eject, you won't see the trash on your desktop since the relevant trash folder is on the card, but that doesn't mean that "trash" is empty.
Hope this helps.
