[SATLUG] SMART error (CurrentPendingSector) detected on host

[Sean Carolan]

This is the first time I've ever gotten one of these.  I was wondering
if I would ever hear from smartd in this lifetime:

> The following warning/error was logged by the smartd daemon:

So I ran smartctl:

[scarolan at computer ~]$ sudo smartctl -H /dev/hdb
smartctl version 5.36 [i686-redhat-linux-gnu] Copyright (C) 2002-6 Bruce Allen

SMART overall-health self-assessment test result: PASSED

Is there anything to be concerned about here?
