While bad sectors occur over time, they aren't normal.

You should install smartmontools (assuming you run FreeBSD 5.x or  
later) and have it run a drive self-test, and monitor the counts of  
bad sectors being reallocated and other errors.  If you don't see  
anything bad and no additional bad sectors appear over the next few  
weeks, you can probably live with it as an isolated incident.

Of course, you should also be prepared to recover your data from  
backups in case the drive decides to die completely, as it may do  
just that...
