Parameter Code
The Parameter Code is set to 0000h.
DU
A Disable Update (DU) bit set to 0 indicates that the
Drive is free to update the counter.
A DU bit set to 1 indicates that the Drive shall not
update the counter except in response to a LOG SELECT
command that specifies a new value for the counter.
The initiator may use the LOG SELECT command to set or
clear the DU bit.
The Drive will set the DU bit to 1 when the counter
reaches its maximum value (FFFFFFFFh).
DS
The Disable Save (DS) bit is set to 1 to indicate that
the Drive does not support saving of this log parameter.
(Note: This bit can not be changed by the initiator)
