+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
