Preface This manual describes the MHS2060AT, MHS2040AT, MHS2030AT and MHS2020AT 2.5-inch hard disk drives with a built-in controller that is compatible with the ATA interface. This manual explains, in detail, how to maintain the disk drives. This manual assumes that users have a basic knowledge of hard disk drives and their application in computer systems.
Preface In the text, the alert signal is centered, followed below by the indented message. A wider line space precedes and follows the alert message to show where the alert message begins and ends. The following is an example: (Example) Don’t install or remove a PCA or connect or disconnect a cable or connector plug when the drive is powered. This may give you an electric shock. The main alert messages in the text are also listed in the “Important Alert Items.
Important Alert Items Important Alert Messages The important alert messages in this manual are as follows: This manual uses the key alert messages given below. The following manual also contains notes on safety precautions: A hazardous situation could result in minor or moderate personal injury if the user does not perform the procedure correctly. Also, damage to the predate or other property, may occur if the user does not perform the procedure correctly.
Important Alert Items Task Maintenance Alert message Page Device damage 1. Before touching a PCA or the drive, wear a wrist strap and perform the human body grounding to discharge static electricity from your body. This will prevent irreparable damage to the PCA and the head of the drive. 2. Don’t install or remove a PCA or connect or disconnect a cable or connector plug when the drive is powered. This will prevent electrical damage to the disk drive. 3.
Important Alert Items Task Maintenance C141-F059-01EN Alert message Page Damage or Device damage 1. Perform any removal after the system power is completely disconnected. The cable must not be disconnected and the screws that attach the drive must not be removed with the power ON. 2. Do not move the drive until it comes to a complete stop (about 30 s after the power is turned OFF). 3. Perform the human body grounding to discharge any static electricity from your body.

CHAPTER 1 Maintenance and Diagnosis 1.1 Maintenance 1.2 Operation Confirmation 1.3 Troubleshooting Procedure This chapter describes the maintenance, diagnosis, operation check, and troubleshooting of the disk drive.
1.1 Maintenance 1.1 Maintenance and Diagnosis Maintenance 1.1.1 Rules for maintenance The following cautions must be observed to prevent injury during troubleshooting or maintenance. Static, Damage 1. Don’t install or remove a PCA or connect or disconnect a cable or connector plug when the drive is powered. This may give you an electric shock. 2. Keep away from mechanical assemblies in the unit during operation. This may cause injuries. 3. Avoid dangerous detergent when the disk drive is cleaned.
Maintenance and Diagnosis 1.1 Maintenance 1.1.2 Maintenance requirements (1) Preventive maintenance The disk drive needs no preventive maintenance, not even the air filter needs to be changed. Device damage The DE is completely sealed. Do not open the DE in the field. (2) Service life In situations where management and handling are correct, the life of the disk drive is five years when the DE surface temperature is less than 48°C.
1.1 Maintenance Maintenance and Diagnosis Data corruption When asking for repair, save all data stored in the disk drive beforehand. Fujitsu Limited is not responsible for any loss of data during service and repair. (5) Notes on handling a. General notes a) Vibrations and shocks more severe than allowed will cause fatal damage to the device so be very careful. Be especially careful when unpacking the device. b) Do not leave the device in a dusty environment. c) b.
Maintenance and Diagnosis 1.1 Maintenance b) It is recommended that you use the shock absorption cushion material and packaging that contained the device when it was delivered by Fujitsu. If the same packaging material cannot be used, use a shock absorbent box that will transmit shocks directly to the device. When using this type of box, adequately protect the PCA surface and interface connector section. e.
1.1 Maintenance Maintenance and Diagnosis 1.1.4 Disk drive revision number The disk drive revision number is a single alphabetic character followed by a single alphanumeric character. It is stuck on the DE and marked on the revision number label. Figure 1.1 shows the disk drive revision number label format. Disk drive revision number Firmware code/revision Figure 1.
Maintenance and Diagnosis 1.1 Maintenance Revision number mark when delivered A2 Revision Revision number change in the field A3 Revision Figure 1.
1.1 Maintenance Maintenance and Diagnosis 1.1.5 Tools and test equipment At the field maintenance level, only ordinary hand tools are required for troubleshooting and repairing the disk drive. Special tools and test equipment is not required. Factory level tools and test equipment are beyond the scope of this manual. 1.1.6 Self-diagnostics The disk drive has the following self-diagnostics. These self-diagnostics allow normal basic operation of an isolated disk drive can be checked.
Maintenance and Diagnosis 1.1 Maintenance Start Check the host system (Table 1.1) Yes Operation test with the host computer or test equipment System normal? No Analyze the system related failure Yes Disk drive replacement or repair Test acceptable? Yes Continue with the operation No Disk drive normal? No Yes Diagnostic test with the host computer or test equipment Test acceptable? No Yes Test using voltage or temperature stress Test acceptable? No Disk drive failure analysis (Table 1.
1.2 Operation Confirmation Maintenance and Diagnosis Table 1.1 Status register contents Status bit Contents BIT0=1 Shown in Table 1.2 BIT1, 2 Normal. BIT3=1 (1) Check whether vibration is transmitted because of the way the disk drive is mounted. BIT4=1 (2) Check the power, cable, and connector. BIT5=1 (3) If it is concluded that the disk drive is the cause, replace the disk drive. BIT6=0 BIT7=1 Table 1.
Maintenance and Diagnosis 1.3 Troubleshooting Procedure 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.
1.3 Troubleshooting Procedure Maintenance and Diagnosis Table 1.3 System level and field troubleshooting Check to be made Recommended work DC power voltage level Confirm that the DC power voltage is within ±5% of the standard value. When measured at pins 41 and 42 of the power supply connector, the +5 VDC must be 4.75 to 5.25 VDC. DC power ripple noise Check that the maximum ripple at +5 VDC power is less than 100 mV peak to peak and 200 mV peak to peak respectively.
Maintenance and Diagnosis 1.3 Troubleshooting Procedure 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 with the media defect list to repair.
