• PERF (Performance) bit is not used and ignored internally by the Target.
• EBF (Enable Background Function) bit is not used and ignored internally by the drive.
• EWASC (Enable Warning ASC) bit of zero indicates that Temperature Warnings will not be reported. An EWASC bit of
one allows Temperature Warnings to be reported if the temperature inside the disk enclosure exceeds the threshold
set in Mode Page 00h. The Method of Reporting field controls the reporting method. EWASC is independent of
DEXCPT.
• DEXCPT (Disable Exception Control) bit of zero indicates information exception operations are enabled. The reporting
of information exception conditions when the DEXCPT bit is set to zero is determined from the Method of Reporting
field. A DEXCPT bit of one indicates the Target disabled all information exception operations.
• TEST bit of one instructs the drive to generate false drive notifications at the next interval time, (as determined by the
INTERVAL TIMER field), if the DEXCPT is zero. The Method of Reporting and Report Count would apply. The
false drive failure is reported as sense qualifier 5DFFh. The TEST bit of zero instructs the drive to stop generating
any false drive notifications.
• LOGERR (Log Errors) is not used and ignored internally by the Target.
