To your problem:
Try to format the SD-Card in the pineapple. Go to your pineapple webinterface -> Advanced, press the arrow down beside "USB" and choose Format SD Card. Then test it again. On the otherside, is the SD-Card still ok and healthy ? The SD-Card works well in any other device ?
Try to copy some files on the shell to your card. Maybe you will see there some more infos. What kind of card do you use ?
