Hi. I just bought a SD $ GB memory card to my mobile phone (Nokia 6110 Navigator) so that I can store more photos. However, I needed to backup the data of the old card. I put it into a card reader and I copied all it's contents to my Mac. Then I inserted the new card and I tried to copy all the files to the new card. But I get the followng message: I checked the permissions with "Get Info": I can read and write all the files. I changed the files to another folder. I still can't copy it back... Any help, please?
