To troubleshoot the failure reported in the test at this level, accurately reproduce the condition that caused the failure. Then, by replacing the disk drive, try to separate the fault from the other sections of the disk drive host system.

1.2.2Diagnostic test

The diagnostic test is used to separate a confirmed disk drive failure to a disk drive subassembly or to check the disk drive performance. A test of this level usually includes a specific disk drive function or concentrated execution of a group of functions. The test is usually performed by a factory engineer and not where the failure was reported. The disk drive is tested using another host computer or test equipment.

To troubleshoot the disk drive failure in the diagnostic test, the engineer will reproduce the failure condition. The engineer then isolates the failure to a subassembly or part of the disk drive.

The procedures used in a test of this level great depend on the test equipment used. It is beyond the range of this manual.

1.3Troubleshooting Procedure

1.3.1Troubleshooting procedure

This section describes the troubleshooting procedures for a disk drive failure at field maintenance level described in Subsection 1.1.3.

In this section, troubleshooting is made to isolate the reported failure to the disk drive or a host system. Usually, troubleshooting is necessary only when a cause of failure is uncertain or unknown. When a cause of failure is clear (for example, abnormal sound in the DE or burnt parts on the PCA), a level of troubleshooting is low.

1.3.2Troubleshooting disk drive replaced in field

It is recommended that the whole drive be replaced in maintenance of this level. If replacing the drive corrects the fault, return the old drive to the factory for testing and repair. If the new drive shows the same fault as the one that was removed, the failure is elsewhere in the system.

System level troubleshooting, shown in Table 1.3, is performed at the user site to isolate the reported failure to the disk drive or system.
