Plug the nokia with sd card into pc via usb & can extract the sd card stuff from the card to the pc without need of a card reader.
Some files dont read on other phones as they may on nokia, u need to refer to the samsung handbook with your phone as to what files it does read, i had the same problem as my new phone wont read wma files but reads mp3 so converted wma to mp3 with files taken from card onto pc, & formatted card with new phone then transfered them back corrected. Problem solved
