Removing write protection
Don't ask why THIS worked. I tried taping the notch and removing Read-Only protection under properties as described. Neither worked. I was copying and pasting music to the Micro SD for my Samsung SGH-A867 Eternity. I got the write protection error messages repeatedly until I tried changing the Micro SD CE Adapter for the USB MultiCard Reader/Writer. The Polaroid adapter did not work but Kingston one did. Go FIGURE!!
