The second part is executed after the spindle motor is started. This includes disk access (seek), R/W
channel, and error correction circuitry verification. A reserved area on the disk is used for this test.
Both tests are performed as a result of the SEND DIAGNOSTIC command. The SEND DIAGNOSTICS
will fail with CHECK CONDITION status if it is issued while the spindle motor is not turning. (Such as
after STOP command has been received.)
Note: The self diagnostic is also performed at Power On Reset time.
Note: The SCSI bus signals will not be corrupted when the device is executing the SEND DIAGNOSTIC
command.

The address to be translated is passed to the target with the Send Diagnostic command and the results

The target will read the parameter list from the initiator and, if no errors are detected in the parameter
list, Good Status will be returned. The data translation will be performed upon receipt of the Receive
Diagnostics command.
