2 - 21Chapter 2 Operation of DiagnosticDC355 HDD DIAGDescription: Performs setups, change judgments, etc. when changing or checking HDD.• HDD read verification test can be performed.• HDD partition size can be checked.• HDD partition size can be set.• HDD (file system) can be set up.• HDD fault diagnosis can be performed.• SMART (Self-monitoring, analysis and reporting technology) of HDD can be executed to predictHDD failure.• Any operation cannot be interrupted.• If any failure unrelated to an operation occurs, the operation can be continued.• Any setting made in the [Partition setting] screen is enabled after M/C is rebootedusing the Diag Exit screen.• If M/C is rebooted after making settings in the [Partition setting] screen, rebootingis performed automatically again during M/C initialization.• Any operation to activate HDD cannot be executed before exiting the Diag modeafter [Partition setting]. However, the following operations can be executed:(1) Checking a partition size(2) Setting a partition size• If you make settings in the [Partition setting] screen several times, the last settingis enabled."It takes a long time (approximately 20 minutes for 4GB) to execute a readverification test ("Read Verify Test"). So, if an error code which seems to be relatedto HDD is shown (including any error which disappears when HDD is removed), it ispractical to execute a fault diagnosis and prediction and to set (= format) a partitionsize ("Partition setting") before changing HDD.Procedure:1. Enter the Diag (C/E) mode, and select [Diag. Menu Fault Diag.] in the same hierarchical level usingthe " ↓ " key.2. Select the [Fault Diag. DC140 Monitor] screen in a lower level using the " → " key.3. Select [Fault Diag. DC355 HDD DIAG] in the same hierarchical level using the " ↓ " key.4. Select the [DC355 HDD DIAG Read Verify Test] screen using the " → " key.5. Show the setting item screen using the " → " key again. Then, to perform read verification tests ofall partitions, follow the step below. To perform a read verification test of each partition individually,go to the step 6.(1) Select [Read Verify Test If OK press SEL] in the same hierarchical level using the " ↓ " key.Read Verify TestPartition ALL
