Procedure 4 Diagnostic Test Program Execution Check

The HDD test program is stored in the Diagnostics Disk. Perform all of the HDD tests in the Hard Disk Drive Test. Refer to Chapter 3, Tests and Diagnostics, for more information about the HDD test program.

If an error is detected during the HDD test, an error code and status will be displayed. Replace the HDD with a new one following the instructions in Chapter 4, Replacement Procedures. The error codes and statuses are listed in Table 2-4. If an error code is not generated or the problem still exists, go to Procedure 5.
