The error was:
Apr 18 14:01:45 smartd[2104]: Device: /dev/sdc, 3 Currently unreadable
(pending) sectors
These are not ECC errors and the definition I have for pending sector
errors is, "Current count of unstable sectors (waiting for remapping)."
It would be useful to see the Reallocated Sectors Count from the
smartctl output.
