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 3, it is wise to run readall with the -b
flag first on all the hard disks.
