You can't. Modern hard disks handle this by themselves in a process that is transparent for the user (they "mark" the bad sectors so they are not used again). You have to worry though if this value (Current_Pending_Sector) starts increasing very quickly. After all, as you are using "raid 1" you are covered by this (i.e., a hard disk failure), right? ;-P >> I also did not have such a problem.

Sure you do. What's connected to ata1.00? (dmesg | grep -i ata1.00) These errors are usually derived not from "bad sectors" but a hardware issue (e.g., bad/loosey cabling). Just to be sure, you can run a full SMART test to diagnose any problem from the disk and better if you use the hdd manufacturer's test disk tools which are usually run from a small live-cd iso.
