Fuze is refreshing something

This past week I was on vacation and with no computer available did not add or delete anything for several days.  At the end of vacation, the Refresh Demon took over.  Refresh normally takes me about 5 minutes (16gB card)…but now it kept cycling.  As soon as the progress bar was complete, it started again.  Soft reset had no effect.  I removed the MicroSD card and started again.  No problem now.  I added the card back in and the problem resumed.  Finally I got refresh to stop and got some music to play, but it was “choppy”.  I got a little “glitch” of silence every 3 seconds or so.  I soft reset a couple of more times and the problem has finally gone away.

I’m very organized with tags, there was no problem before the incident and no problem after.  Nothing added or deleted to card or Fuze before or after.  Weird.
