If you have the possibility to run a scrub of the pool, there should  
be no additional checksum errors accouring *after* the scrub is  
*finished*. If checksum errors still appear on this disk after the  
scrub is finished, you should have a look at the hardware (cable/disk)  
and take appropriate replacement actions.
