Command Specifications
If the HDD performs rounding processing ("rounding up" or "rounding down") of
parameter values specified by the INIT, in some cases a "CHECK CONDITION"
status (RECOVERED ERROR [=1] / Rounded parameter [37-00]) is reported, and
in some cases it is not reported.
Whether or not the CHECK CONDITION status is reported depends on whether
"rounding up" or "rounding down" is specified.
If the INIT would like to confirm that the HDD is implementing rounding
processing, it issues a MODE SENSE or MODE SENSE EXTENDED command
after issuing this command and reads the values for the "Current" parameters, then
compares them with the parameter values sent in the MODE SELECT command.
Parameter fields which are the object of rounding processing are explained in the
descriptions of each page descriptor in this item.
Table 4.12 lists the data configuration of the parameter list transferred by the INIT
in this command. The parameter list is configured from header 4 bytes in length
followed by a block descriptor with a length of 8 bytes. This is followed by one or
more page descriptors, or, when there is no block descriptor the 4-byte header is
followed by one or more page descriptors. The INIT may transfer a header only,
or the header and block descriptor only without the page descriptor added.
