CHAPTER 6 Diagnosis and Maintenance

This chapter contains diagnosis and maintenance information.

6.1 Diagnosis

Table 6.1 shows a test executed by the diagnostic function.

The drive has a self-diagnostic function. This function can check the basic
operations of the drive.

A test program running in the host system is required to check general operations,
including operations of the interface with the host system. (See Subsection 6.1.3.)
