A couple of days ago it occurred to me that check_smart didn't correctly create graphs for the defect list performance data. I would have wanted to have a graph which shows the increasing number of defect blocks/sectors over time. 

The newest version 4.2 allows the correct graphing and also correctly displays the critical threshold in the graph if the -b parameter was used.

You can find the plugin here: Nagios Plugins / check_smart plugin to monitor HDD SMART values

The following graph shows the increasing number of defect entries over a short period of time. Such graphing might help indicate a failing disk:

Increasing number of defect sectors
