1.2 Operation Confirmation
1.2 Operation Confirmation
1.2.1 Operation test
When the host computer is processing data, the disk drive monitors disk drive
operation errors including data, command, and seek errors. The host is notified of
the error that the disk drive detected and the user is notified of its result.
The user may notice intermittent and indefinite failures such as overlong
execution time, abnormal noise, abnormal odor, or failures in particular processes.
The failure reported in the operation test will need further investigation. To
ascertain the cause of the disk drive failure reported, the disk drive can be
replaced. Failures in the operation test are often not caused by the host system.
For example, not having enough power supply reserve, a loose cable connection,
no timing and mechanical reserves, or relationship with other systems.
In normal operation, the disk drive itself or the host determines the processing
(return or halt) following the detected failure state.
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.
1.2.2 Diagnostic 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.
C141-F074 1-11
Maintenance and Diagnosis
1.3 Troubleshooting Procedure
1.3.1 Troubleshooting 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.
1.3.2 Troubleshooting 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.

To further isolate the failure, if it can be done, execute the system level
diagnostic routine described in the host computer manual.
Check the AC voltage level at the power supply section and recheck the
DC voltage level at the disk drive power supply connector.
If the AC voltage level is abnormal, or if there is a lot of electrical noise,
notify the user.
If the DC voltage level is unstable, replace the power supply section.
If possible, replace the disk drive. If the fault remains, the disk drive is
not the case. For suggestions to isolate the failure further, refer to the
hardware and software manuals provided with the system.
C141-F074 1-13
Maintenance and Diagnosis
1.3.3 Troubleshooting at factory
When the trouble is recovered by replacing the drive at field (Subsection 1.3.2),
troubleshoot the replaced drive to isolate the trouble to the subassembly parts.
To shorten the troubleshooting time and repairing time, gather the data, such as
environmental data and other information, from the user and then return the failed
drive to the factory to repair.
At the factory, user environment is made and a reappearance test is performed.
To reappearance a same trouble at user, the failed drive is connected to the host
system. If no trouble occurs by the normal test, the reappearance test is
performed by adding the voltage/temperature load using a disk drive tester or
tools according to the user environment.
When a trouble reappeared, troubleshoot the cause of failure. Then, replace the
failed unit or parts.
As this level maintenance is made by a factory, this maintenance level is beyond
the scope of this manual.
Device damage
The disk enclosure (DE) must never to be opened in the field.
Opening the disk enclosure may cause irreparable damage.

CHAPTER 2 Removal and Replacement Procedure
2.1 Spare Parts
2.2 Disk Drive Removal
This chapter explains the procedure for removing and replacing the disk drive. It
is assumed that the reader has a thorough knowledge of replacing the complete
disk drive and replacing the power-interface cable.
When carrying out these procedures, note the following items.
• Be sure to wear a wrist strap when removing the disk drive from the host
system.
• The disk drive must have been removed from the host system.
• A power-interface cable to the disk drive must be disconnected.
• Mounting is done by reversing the steps for removal.
To carry out maintenance properly, observe the following:
• Place removed screws and other parts where they will not get lost or
damaged.
• Keep a record of all maintenance work.
• Tighten screws securely but not excessively.
• Before touching the PCA, wear a wrist strap and check it is grounded to
discharge any static electricity from your body. This ensures that the worker
will not electrically damage the PCA.
• Do not push the DE cover under any circumstances.
