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.
