6.1.1Initial self-diagnosis

When the power is turned on, the optical disk drive starts initial self-diagnosis. Basic hardware functions are tested during initial self-diagnosis.

The hardware function test checks the normality of the basic controller operation. This test includes the normality check of the ROM in which microcodes are stored, microprocessor (MPU) peripheral circuit test, memory (RAM) test, and data buffer test.

If an error is detected during initial self-diagnosis, the LED on the drive front panel blinks.

6.1.2Diagnostic command

The host system can make the ODD execute the self diagnosis by issuing the EXECUTIVE DEVICE DIAGNOSTIC command. See Section 4.7.2, “EXECUTIVE DEVICE DIAGNOSTIC”, in details.

6.1.3Test program

A test program running in the host system is required to check general operations such as operations of the interface with the host system and simulated operations.

The configuration and function of the test program depend on the user system requirements. The test program should include the following tests:

(1)Random/sequential read test

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

(2)Write/read test

Use a disk whose operation check data may be destroyed so that a write or read test can be executed with an arbitrary data pattern.
