3.3.3.1  RAID : OPTIMAL 
When RAID is “OPTIMAL” (Both the two drives are normal), it is judged that RAID 
configuration is normal. There are the following reasons why the repair is requested.  
Abnormal noise of the motor from the HDD: 
Refer to the 2.5-HDD trouble shooting in Chapter 2, Troubleshooting Procedures. 
Access to the HDD is very slow: 
Display the drive log by using Independent Utility of the DIAGNOSTIC 
PROGRAM. Check if ten or more continual logs of the message indicating retry 
such as “Write Error occurred, Retry the command.” or “Other Read Error occurred 
are recorded in the drive log of either HDD. If recorded, the drive is failed and 
should be repaired. Refer to Independent Utility in Appendix J. 
In the other case above mentioned, it is judged that the MB side fails.
