It happens with my lumia 820 as well. After some work I found out, that once I insert my sd card in samsung mobile, because of that some hidden config files were stored on the card. So when we insert sd card in lumia it founds the config files of samsung. Thats why it is giving the error, with a simple solution for it, the sd card need to be formatted with a card reader. It works for me, try your luck.
