7.2.5. RECEIVE DIAGNOSTIC RESULT command
Whenever a diagnostic test is executed, the drive automatically prepares a diagnostic test result that can be
returned to the host computer when a RECEIVE DIAGNOSTIC RESULT command is issued.
If the PF bit in the SEND DIAGNOSTIC command was sent to one, the diagnostic test result will be preceded by a
four-byte header which will be of the form:
Table 7-3: RECEIVE DIAGNOSTIC RESULT - SCSI-2 Header
Bit
Byte
7 6 5 4 3 2 1 0
0 Page Code (81h)
1 Reserved
2 (MSB) Page Length (00 05h)
3 (LSB)
Regardless of the PF bit in the SEND DIAGNOSTIC command, the five bytes of diagnostic test result information
will be of the form:
Table 7-4: RECEIVE DIAGNOSTIC RESULT

Reset error: This bit is set when an error occurs during power-on self-test.
Time Re-Sync: This bit indicates that the time stamp saved with the error log has no relation to that of the
previous entry. It is only set by the logging routine within the data buffer as an error is logged.
