[6.6.6] Unreasonable number of writes reported

One of my disks reported a HUGE number of writes (see Main.pdf) immediately after restarting unraid.

I was unmounting and remounting disk6 to rebuild it.  disk5 had the large number of writes and the write errors when I mounted disk6 and restarted.....  I've had this happen with disk5 a couple of times in the past.

This is with stable 6.6.6 unraid - log attached.
