NAME
       readall - read a device quickly to check for bad blocks

SYNOPSIS
       readall [-bt] file

OPTIONS
       -b     Produce shell script on stdout that calls badblocks

       -t     Just print device size

EXAMPLES
       readall /dev/hd0    # Read all of /dev/hd0

       readall -b /dev/hd1 >s
			   # Generate shell script on s

DESCRIPTION
       Readall reads all of the named device in large chunks.  It reports about blocks that it cannot read.  Unlike diskcheck, it does not attempt
       to write on the disk, making it safer to use when one is worried about a sick system.  When the -b flag is given, the  output  is  a  shell
       script  that  calls  the  badblocks program to marked all the bad blocks.  Whenever installing MINIX, it is wise to run readall with the -b
       flag first on all the hard disks.

SEE ALSO
       badblocks(8).
