Parameter Data Format
This bit of zero indicates the target disables reporting of the warning. The
"MRIE" field is ignored when "DExcpt" is set to one and "EWASC" is set to
zero. An "EWASC" bit of one indicates warning reporting is enabled. The
method for reporting the warning when the "EWASC" bit is set to one is
determined from the "MRIE" field.
These bits are used to indicate DE temperature elapse (see 7.6.3, "Failure
prediction method"), and the EBACKERR bit is used to determine whether
errors are reported (see "f. EBACKERR (Enable Background Error)").
d.
DExcpt (disable exception control)
This bit of zero indicates information exception operations is enabled. The
reporting of information exception conditions when the "DExcpt" bit is set to
zero is determined from the method of reporting informational exceptions
field. A "DExcpt" bit of one indicates the target disables all information
exception operations. The method of reporting informational exceptions field
is ignored when "DExcpt" is set to one.
The value of this bit is used to determine whether the HDD may report a
failure prediction status according to the SMART function to the initiator.
(See Section 7.6, "SMART (Self Analysis and Reporting Technology").
e. TEST
"1":
"0":
The value of this bit cannot be saved, and the stored value is fixed at 0. The
current value is initialized to 0 when power is turned on or when Hard
Reset/LU Reset is received.
318
If "0" is set for DExcpt, a failure prediction is reported with a failure
prediction reporting condition that is generated when the time specified
with Interval Timer has elapsed.
The method and number of times of this reporting are determined
according to the specifications in the MRIE and Report Count fields.
At this time, the sense key of 0x5D and additional sense code of 0xFF
are reported.
This specifies that the test of the failure prediction function and its
reporting method be disabled.
