Reformat the card by hand.
mkfs.vfat -F32 /dev/mmcblk1p1
Make sure that’s the right device name by checking dmesg 
Test some more, and if you still have any problems, zero the device (dd if=/dev/zero of=/dev/mmcblk1), repartition, and then reformat it. If you still have troubles with the card, return it to the store.
