I am unable to copy any files to the card, or delete any files from the card. I can copy files from the card to the laptop. But, I tried a Sandisk usb cf card reader, and now I have read and write permission.
So you are right, there must be a problem with my built in sd card reader. I was wondering when I would notice some new problem, since the Apple Care has expired.
