A cron job runs logwatch nightly and part of the summary is from smartd. Over the past few days entries like the following have appeared: /dev/hdb : Prefailure: Seek_Error_Rate (7) changed to 100, /dev/hdb : Prefailure: Seek_Error_Rate (7) changed to 200, 100, 200, 100, /dev/hdb : Prefailure: Seek_Error_Rate (7) changed to 200, 100, 200, Those are for Jul 09, 10, 12. No Seek_Error_Rate change is reported on the 11th. I know that just because something is labeled "prefailure" doesn't mean it is bad that it changes. Searching I could not find any instance of only this problem being reported. I have never seen it before. No error has been logged nor has any self test (run nightly) failed. Complete info below. Is the Seek_Error_Rate attribute changing a sign of a problem?

I think this looks OK -- no obvious signs of trouble. You have one reallocated sector but no current or offline pending sectors.
