7. ATAPI Packet Command Specification
When MRIE is set to 0, this method instructs the drive to not report informational exception conditions. When
MRIE is set to 4 (Unconditionally generate RECOVERED ERROR), this method instructs the drive to report
informational exception conditions by returning a CHECK CONDITION status on the next command (excluding
Inquiry and Request Sense) after an informational exception condition was detected. The sense key shall be set to
RECOVERED ERROR and the additional sense code shall indicate the cause of the information exception
condition (which is 5D/00h). The command that has the CHECK CONDITION shall complete without error before
any exception condition may be reported (and thus does not need to be reported).
Interval Timer: This field is not supported by the drive and if set a CHECK CONDITION status is returned with an
ILLEGAL REQUEST sense key set.
Report Count: This field has dual purpose. When Test bit is set to ZERO, the value of this field in the MODE
SELECT data represents the Report Count. The Report Count field is not supported by the drive and if set a
CHECK CONDITION status is returned with an ILLEGAL REQUEST sense key set. When a MODE SELECT
command is sent with the Test bit set to ONE, the value of this field in the MODE SELECT data represents the
Test Flag Numnber, which is never returned in response to a MODE SENSE command. Valid values of Test
Number are –64 to 64 and 32767 (7FFFh). Negative numbers are represented using the 2's complement method.
If the Test Flag Number is set to an invalid value, the MODE SELECT command will return CHECK CONDITION
with sense key set to ILLEGAL REQUEST and extended sense set to Invalid Field in Parameter list.
