Diagnostics and Maintenance
6.1.2 Diagnostic command
The host system issues the EXECUTIVE DEVICE DIAGNOSTIC command to cause the ODD to execute
See the description on the EXECUTIVE DEVICE DIAGNOSTIC command for more information.
6.1.3 Test program
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.
