Mi spieghi perch=E8 definisci un superblocco?

 -b superblock
              Instead of using  the  normal  superblock,  use  an
              alternative  superblock  specified  by  superblock.
              This option  is  normally  used  when  the  primary
              superblock has been corrupted.  The location of the
              backup superblock is dependent on the  filesystem's
              blocksize.   For  filesystems with 1k blocksizes, a
              backup superblock can be found at block  8193;  for
              filesystems with 2k blocksizes, at block 16384; and
              for 4k blocksizes, at block 32768.
