c) The spindle motor does not start rotating until the START/STOP UNIT command for the
start is issued. The INIT needs to issue the START/STOP UNIT command to start the
spindle motor by the procedure in Subsection 5.6.2.
d) The disk drive enters the READY status in 30 seconds after the START/STOP UNIT
command is issued. At this time, the IDD reads "system information" from the system
space on the disk.
e) The LED blinks during command execution.
(3) Check items at illegal operation
a) Check that cables are mounted correctly.
b) Check that power and voltages are supplied correctly (measure them with the IDD power
connection position).
c) Check the setting of each setting terminal. Note that the initial operation depends on the
setting of the motor start mode and LED display requirements.
d) If an error is detected in initial self-diagnosis the LED on the front panel blinks. In this
case, it is recommended to issue the REQUEST SENSE command from the initiator (host
system) to obtain information (sense data) for error analysis.
IMPORTANT
The LED lights during the IDD is executing a command.
However, in same commands, the lighting time is only an instant.
Therefore, it seems that the LED blinks or the LED remains off.
