The host system issues the EXECUTIVE DEVICE DIAGNOSTIC command to 
cause the ODD to execute self-diagnostics. 

See the description on the EXECUTIVE DEVICE DIAGNOSTIC command for 
more information. 

To check the operations of the interface with the host system and the general 
operations in an environment that simulates an actual operation status, provide a 
test program that can run in the host system. 

The configuration and function of the test program depend on the requirements of 
the user system. 

To comprehensively test the functions of the optical disk drive, the Fujitsu 
recommends that the test program include the following test items: 

(1) Random/sequential read test 

Use the READ or VERIFY command to test the positioning (seek) and read 
operations in both random access mode and sequential access mode. 

(2) Write/read test 

Using a disk whose data may be erased, execute write/read test based on arbitrary 
data patterns. 

(1) Preventive maintenance 

No preventive maintenance is required. 

(2) Service life 

This drive will not require overhaul within the first five years of installation if it is 
used in an appropriate environment and handled as recommended. 

(3)  Service system and repair 

Fujitsu provides a service system and repair facility for its optical disk drives.  
Submit to your Fujitsu representative information required to replace or repair a 
drive.  Normally, the information includes: 

a)  Optical disk drive model, product number (P/N), revision number, serial 

number (S/N), and date of manufacture
