2.2 Diagnosis
The MO drive has an initial self-diagnosis function, which checks the normal basic
operation of the MO drive.
•
Initial self-diagnosis function
When the power is turned on, the MO drive executes initial self-diagnosis,
which includes a basic test of hardware functions.
If an error is detected during self-diagnosis, the LED on the front panel of the
MO drive blinks. The status can be cleared by turning the power off and then
on again. When this status is cleared, the MO drive re-executes the initial
self-diagnosis.
2.3 Troubleshooting Method
The system-level troubleshooting steps listed below are performed for determining
if the fault is caused by an MO drive unit or caused by a system. The steps should
be performed by customers on-site.
Item Recommended procedure
MO cartridge Check that a recommended MO cartridge is loaded and the surface
of the disk is free from dirt or scratches.
AC adapter Check whether power indicator on the device side has lighted up
before connecting the device between host computer with the USB
cable.
Interface cable connection Check that the interface cable is correctly connected to the MO
drive.
System cable Check that all cables in the system are correctly connected.
System diagnosis test Execute the system level diagnostic routines given in the host
computer manual to further isolate the fault, if possible.
Intermittent or indefinite error Replace the MO drive if possible. If the faulty condition continues
after the replacement, the fault will not be caused by the MO drive.
Refer to the provided hardware and software manuals about the
system further, for clues of identifying cause of the failure.
