6-2 C156-E228-02EN
6.1.2 Diagnostic command
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.
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.
