sginfo




SYNOPSIS

       sginfo [-options] [device]


DESCRIPTION

       sginfo is a re-porting of the  scsiinfo  program  by  Eric
       Youngdale to use the sg devices (rather than the sd, sr or
       st block  devices).  This  program  outputs  "mode  sense"
       information.  Amongst  other  things  it  outputs the full
       defect list of a disk (which was truncated at  4096  bytes
       in  the original). With the '-R' option mode page data can
       be changed (using the SCSI mode select command).

       -c     Display information from Caching Page.

       -C     Display information from Control Mode Page.

                              -Findex     -  defect  bytes   from
              index

              values
