-i input_file
              Read  a list of already existing known bad blocks.  Badblocks will skip testing these
              blocks since they are known to be bad.  If input_file is specified as "-",  the  list
              will  be  read  from  the standard input.  Blocks listed in this list will be omitted
              from the list of new bad blocks produced on the standard  output  or  in  the  output
              file.  The  -b option of dumpe2fs(8) can be used to retrieve the list of blocks cur-
              rently marked bad on an existing filesystem, in a format suitable for use  with  this
              option.

-o output_file
              Write  the  list of bad blocks to the specified file.  Without this option, badblocks
              displays the list on its standard output.  The format of this file  is  suitable  for
              use by the -l option in e2fsck(8) or mke2fs(8).

'Blocks listed in this list will be omitted from the list of new bad blocks produced on the standard output or in the output file.' 이 내용과 관련이 있는건 아닐까요?

It is my think, you can have another..
