+SYNOPSIS
+       badblocks  [  -svwnfBX  ]  [ -b block_size ] [ -c blocks_at_once ] [ -d
+       read_delay_factor ] [ -e max_bad_blocks ] [ -i input_file ] [  -o  out‐

+       [ first_block ]
+
+DESCRIPTION
+       badblocks is used to search for bad blocks on a device (usually a  disk
+       partition).   device  is  the  special file corresponding to the device
+       (e.g /dev/hdc1).  last_block is the last block to be checked; if it  is
+       not  specified,  the  last  block  on  the device is used as a default.
+       first_block is an optional parameter specifying the starting block num‐
+       ber  for  the  test, which allows the testing to start in the middle of
+       the disk.  If it is not specified the first block on the disk  is  used
+       as a default.
+
+       Important  note:  If  the output of badblocks is going to be fed to the
+       e2fsck or mke2fs programs, it is important that the block size is prop‐
+       erly  specified,  since  the block numbers which are generated are very
