So I guess then if no one else has seen this then it's just a dead SD card.

I don't know whether this is related but when I set up my BitTorrent Sync from my desktop to Android HTC One external SD card, it set up OK at first but then wouldn't sync, and now my SD card is not able to accessed. I've tried mounting and unmounting to no avail. Unfortunately I don't have a way to test the card somewhere else. It looks like BTSync killed the SD card!
