                               [--data-size=<size> | -z <size>]
                               [--ref-tag=<reftag> | -r <reftag>]
                               [--data=<data-file> | -d <data-file>]

                               [--app-tag-mask=<appmask> | -m <appmask>]
                               [--app-tag=<apptag> | -a <apptag>]
                               [--limited-retry | -l]

DESCRIPTION

       The Compare command reads the logical blocks specified by the command from the medium and
       compares the data read to a comparison data buffer transferred as part of the command. If
       the data read from the controller and the comparison data buffer are equivalent with no
       miscompares, then the command completes successfully. If there is any miscompare, the
       command completes with an error of Compare Failure. If metadata is provided, then a
       comparison is also performed for the metadata.

OPTIONS
