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": 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.

"0": This specifies that the test of the failure prediction function and its reporting method be disabled.

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.
