  1. No. badblocks only SEARCHES for bad blocks on drive. it does not repairs them. for repair, you can use following commands:

    badblocks /dev/sda1 > badblocks_list

    fsck -t ext3 -l badblocks_list /dev/sda1

    the first command saves the list of bad blocks in a file,which is feeded to fsck to repair.
