PREFACE This manual describes the MPC3032AT, MPC3043AT, MPC3064AT, MPC3084AT, MPC3096AT and MPC3102AT a 3.5-inch hard disk drive with a BUILT-IN controller that is compatible with the IBM PC-AT interface. This manual explains, in detail, how to maintenance the disk drives. This manual assumes that users have a basic knowledge of hard disk drives and their application in computer systems.
Conventions for Alert Messages This manual uses the following conventions to show the alert messages. An alert message consists of an alert signal and alert statements. The alert signal consists of an alert symbol and a signal word or just a signal word. The following are the alert signals and their meanings: This indicates a hazarous situation likely to result in serious personal injury if the user does not perform the procedure correctly.
LIABILITY EXCEPTION "Disk drive defects" refers to defects that involve adjustment, repair, or replacement. Fujitsu is not liable for any other disk drive defects, such as those caused by user misoperation or mishandling, inappropriate operating environments, defects in the power supply or cable, problems of the host system, or other causes outside the disk drive.

Important Alert Items Important Alert Messages The important alert messages in this manual are as follows: A hazarous situation could result in minor or moderate personal injury if the user does not perform the procedure correctly. This alert signal also indicates that damages to the produt or other property, may occur if the user does not perform the procedure correctly. Task Maintenance Alert message 1.
Task viii Alert message 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. Before touching a PCA, perform the human body grounding to discharge static electricity from your body. This will prevent electrical damage to the PCA. 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. Operating the disk drive with one or more PCA missing will be unpredictable. Only power the drive with all boards installed. 4.
(3) Exchangeable parts in field The PCA and the DE cannot be replaced separately in the field. Replace the whole disk drive. (4) Service system and repair Fujitsu Limited has a disk drive service system and repair facility.
• Hold by the DE section, do not directly touch the PCA unit unnecessarily. b. Unpacking a) Use a flat workplace, find which side of the pack is up and be careful not to have the wrong side facing upwards. Do not place the device directly on a hard table, place it on something soft such as a rubber mat. b) Be careful not to apply any excessive force to the packed device when removing the shock absorbing material.
f. Storage 1.1.3 a) Store in dampproof packaging. b) Take care that the environmental requirements satisfy the non-operating environmental specifications described in Section 1.4 in Product Manual. c) To prevent condensation, do not subject the device to sudden changes of temperature. Maintenance levels Because of its compact size and special repair requirements, it is recommended that the whole disk drive be replaced. This section describes maintenance on two levels.
(1) Revision number marking at delivery The machine revision number is indicated by crossing out up to the relevant number in the relevant alphabetic character row using = marks (see Figure 1.2). (2) Revision number change in the field When a part is replaced in the field or other modifications are made, the machine revision number may need to be changed. The level is indicated by crossing out the relevant number in the relevant alphabetic character row using marks (see Figure 1.2).
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. • • 1.1.
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 Test acceptable? No Disk drive replacement or repair Yes Continue with the operation 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? Yes No failure Figure 1.
Table 1.1 Status bit Status register contents Contents BIT0 = 1 Shown in Table 1.2 BIT1, 2 Normal BIT3 = 1 BIT4 = 1 BIT5 = 1 BIT6 = 0 BIT7 = 1 (1) Check whether vibration is transmitted because of the way the disk drive is mounted. (2) Check the power, cable, and connector. (3) If it is concluded that the disk drive is the cause, replace the disk drive. Table 1.
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.
Table 1.3 Check to be made System level and field troubleshooting Recommended work DC power cable Confirm that the power cable is properly connected at the disk drive and power supply section. DC power voltage level Confirm that the DC power voltage is within ±5% (+5 VDC) or ±8% (+12 VDC) of the standard value. When measured at pins 3 and 4 of the power supply connector, the +5 VDC must be 4.75 to 5.25 VDC. When measured at pins 1 and 2 of the disk drive power supply connector the +12 VDC must be 11.
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. At the factory, user environment is made and a reappearance test is performed.
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 powerinterface cable. When carrying out these procedures, note the following items. • • • The disk drive must have been removed from the host system. A power-interface cable to the disk drive must be disconnected.
