how to create file system with less bad block??

[mcclnx mcc <mcclnx@xxxxxxxxxxxx>]

We have CENTOS 4.X and 5.X on DELL servers.  Recently we found some bad blocks happen on databases.  the way we create file system is:
     mke2fs -j /dev/sdXX
Does there has any good way can create file system with less bad block or avoid file system to use bad block?
Thanks.
