Inside a modern SD card
I suppose it's not very surprising, but it still seems interesting to me. This card was "stuck" in that the write-protect nubbin had no effect and the card could not be written-to. So I pulled it appart to see if there was something wrong with the electrical circuit before the "should have been obvious" penny dropped. Nevertheless reassembling (Not even glued, just held-together by the confines of the SD card slot) resulted in the r/w nubbin working again. (That's the little grey nubbin on the right).
