Command:   readall - read a device quickly to check for bad blocks
Syntax:    readall [-bt] file
Flags:     -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

     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.
