CHAPTER 1 GENERAL DESCRIPTION 1.1 Standard Features 1.2 Hardware Structure 1.3 System Configuration This chapter describes the feature and configuration of the MBA3xxxxx. The HDDs are high performance large capacity 3.5-inch hard disk drives with an embedded SCSI controller. The HDDs support the Small Computer System Interface (SCSI) as described in the ANSI SCSI SPI-4 [T10/1365D Rev.10] to the extent described in this manual.
1.1 Standard Features (1) Compactness Since the SCSI controller circuit is embedded in the standard 3.5-inch hard disk drive form factor, the HDD is extremely compact. The HDD can be connected directly to the SCSI bus of the host system. (2) Environmental Protection The HDDs comply with the Restriction of the use of certain Hazardous Substances in electrical and electronic equipment (RoHS) directive issued by European Union (EU).
(5) High speed data transfer Such a high data transfer rate on the SCSI bus can be useful with the large capacity buffer in the HDD. • 8-bit SCSI: The data transfer rate on the SCSI bus is 40 MB/s maximum at the synchronous mode. • 16-bit SCSI: The data transfer rate on the SCSI bus is 320 MB/s maximum at the paced transfer synchronous mode. Note: The maximum data transfer rate in asynchronous mode may be limited by the response time of initiator and the length of SCSI bus length.
IMPORTANT When Write cache is enabled, you should ensure that the cached data is surely flushed to the disk media before you turn off the HDD's power. To ensure it, you should issue either the SYNCHRONIZE CACHE command or the STOP UNIT command with specifying “0” to the Immediate bit and then confirm that the command is surely terminated with the GOOD STATUS. (9) Command queuing feature The HDD can queue maximum 128 commands, and optimizes the issuing order of queued commands by the reordering function.
(14) Defective block slipping A logical data block can be reallocated in a physical sequence by slipping the defective data block at formatting. This results in high speed contiguous data block processing without a revolution delay due to defective data block. (15) High speed positioning A rotary voice coil motor achieves fast positioning with high performance access control.
1.2 Hardware Structure The HDDs have a disk enclosure (DE) and a printed circuit board assembly (PCBA). The DE includes the heads on an actuator and the disks on a spindle motor mounted on the DE. The PCBA includes a read/write circuit and a controller circuit. (1) Disks The disks have an outer diameter of 70 mm (2.8 inch). (2) Heads The heads have MR (Magnet-Resistive) read element Ramp Load type slider. (3) Spindle motor The disks are rotated by a direct-drive hall-less DC motor.
1.3 System Configuration Figure 1.1 shows the system configuration. The HDDs are connected to the SCSI bus of host systems and are always operated as target. The HDDs perform input/output operation as specified by SCSI devices which operate as initiator. SCSI bus HDD HDD (#14) (#15) Figure 1.
(1) SCSI bus configuration Up to eight SCSI devices operating as an initiator or a target can be connected to the SCSI bus for the 8-bit SCSI and up to 16 SCSI devices operating as an initiator or a target can be connected to the SCSI bus for the 16-bit SCSI in any combination. For example, the system can be configured as multi-host system on which multiple host computers that operate as initiator or connected through the SCSI bus.

2.1.5 Reliability (1) Mean Time Between Failures (MTBF) MTBF of the HDDs during its lifetime is 1,400,000 hours (operating: 24 hours/day, 7 days/week average DE surface temperature: 50°C or less). Continual or sustained operation at case DE surface temperature above 50°C may degrade product reliability.
Note: The "average DE surface temperature" means the average temperature at the DE surface throughout the year when the HDD is operating. (4) Data security at power failure Integrity of the data on the disk is guaranteed against all forms of DC power failure except on blocks where a write operation is being performed. The above does not applied to formatting disks or assigning alternate blocks.

CHAPTER 3 DATA FORMAT 3.1 Data Space 3.2 Logical Data Block Addressing 3.3 Defect Management This chapter explains data space definition, logical data block addressing, and defect management on the HDD. 3.1 Data Space The HDD manages the entire data storage area divided into the following three data spaces.
Note: Spare sectors on the last track in each cell are not necessarily placed at the end of the track because of a track skew or a cylinder skew. (Details are explained in Subsection 3.1.3.) Figure 3.1 Cylinder configuration Apart from the above logical configuration, the HDD intends to increase the storage capacity by dividing all cylinders into several zones and changing a recording density of each zone.
(1) User space The user space is a storage area for user data. The data format on the user space (the length of data block and the number of data blocks) can be specified with the MODE SELECT or MODE SELECT EXTENDED command. The user can also specify the number of logical data blocks to be placed in the user space with the MODE SELECT or MODE SELECT EXTENDED command.
The number of spare sectors per cell is fixed at 300. This number cannot be changed by users. Track 0 Sector 0 1 n-m-1 n-m n-2 n-1 Track 1 n n+1 2n-m-1 2n-m 2n-2 2n-1 Cell Last track SPR1 SPR299 SPR300 Spare sectors (300 sectors) Note: This HDD manages alternate spare areas for each cell, which is a set of cylinders. One cell consists of 32 to 40 cylinders. Figure 3.
3.1.3 Track format (1) Physical sector allocation Figure 3.4 shows the allocation of the physical sectors in a track. The length in bytes of each physical sector and the number of sectors per track vary depending on the logical data block length. The unused area (G4) exists at the end of the track in formats with most logical data block lengths. The interval of the sector pulse (length of the physical sector) is decided by the HDD internal free running clock frequency.
Track skew Head Track skew Head skew Head Leading logical sector in head p+1 Figure 3.5 Track skew/head skew The number of physical sectors (track skew factor and head skew factor) corresponding to the skew time varies depending on the logical data block length because the track skew and the head skew are managed for individual sectors. The HDD automatically determines appropriate values for the track skew factor and the head skew factor according to the specified logical data block length. 3.1.
(1) Gaps (G1, G2, G3) No pattern is written on the gap field. (2) PLO Sync In this field, pattern X'00' in the specified length in bytes is written. (3) Sync Mark (SM1, SM2) In this field, special pattern in the specified length in bytes is written. This special pattern indicates the beginning of the data field. (4) Data field (DATA1-DATA4) User data is stored in the data field of the sector.
3.1.5 Format capacity The size of the usable area for storing user data on the HDD (format capacity) varies according to the logical data block or the size of the spare sector area. Table 3.1 lists examples of the format capacity when the typical logical data block length and the default spare area are used. The following is the general formula to calculate the format capacity.
(1) Block address of user space The logical data block address number is consecutively assigned to all of the data blocks in the user space starting with 0 to the first data block. The HDD treats sector 0, head 0, and cylinder 0 as the first logical data block. The data block is allocated in ascending order of addresses in the following sequence (refer to Figure 3.5): 1) Logical data blocks are assigned in ascending order of sector number in the same track.
3.3 Defect Management 3.3.1 Defect list Information of the defect location on the disk is managed by the defect list. The following are defect lists which the HDD manages. • P list (Primary defect list): This list consists of defect location information available at the disk drive shipment and is recorded in a system space. The defects in this list are permanent, so the initiator must execute the alternate block allocation using this list when initializing the disk.
The alternate block allocation is executed by the FORMAT UNIT command, the REASSIGN BLOCKS command, or the automatic alternate block allocation. Refer to Subsection 5.3.2 “Auto alternate block allocation processing” of the SCSI Logical Interface Specifications for details of specifications on these commands. The logical data block is allocated to the next physically continued sectors after the above sector slip treatment is made.
: n represents a logical data block number : Defective sector : Unused spare sector Figure 3.7 Alternate block allocation by FORMAT UNIT command During FORMAT UNIT command, alternate block allocation is conducted in following cases: 1) Unrecovered write offtrack condition during a media write 2) Uncorrectable Data Error during a media read (certification) *1 If above errors are detected during FORMAT UNIT command, the HDD allocates the alternate block(s) to the defective data blocks.
(2) Alternate block allocation by REASSIGN BLOCKS command When the REASSIGN BLOCKS command is specified, the alternate block is allocated to the defective logical data block specified by the initiator by means of alternate sector treatment. The alternate block is allocated to unused spare sectors in the alternate cylinder. Figure 3.8 is examples of the alternate block allocation by the REASSIGN BLOCKS command. Example Reassign: Block 16.
• Automatic alternate block allocation at write operation If AWRE flag in the MODE SELECT parameter permits the automatic alternate block allocation, the HDD executes two kinds of automatic alternate processing during WRITE command processing as described below: Type 1 (Reassignment of uncorrectable read error sector) 1) Commands to be applied WRITE WRITE EXTEND WRITE at executing WRITE AND VERIFY 2) Application requirements When any of the above commands is issued to LBA registered in the uncorrectable e
2) Application requirements / processing When WRITE/WRITE EXTENDED command detects any Servo error (e.g. Write offtrack error) and cannot be recovered within pre-determined retry number (specified in Mode Parameter). For the sectors around defective Servo, alternate blocks are allocated and the data of this WRITE commands are re-written.

c) In a system which does not use the terminating resistor power supply signal (TERMPWR) on the SCSI bus, the requirements for +5 VDC given in Figure 4.10 must be satisfied between the HDD and the SCSI device with the terminating resistor circuit. SCSI devices with the terminating resistor Figure 4.
(4) Sequential starting of spindle motors After power is turned on to the HDD, a large amount of current flows in the +12 VDC line when the spindle motor rotation starts. Therefore, if more than one HDD is used, the spindle motors should be started by the following procedures to prevent overload of the power supply unit. Regarding how to set a spindle motor start control mode, see Subsection 5.3.2. For the NP model drives, the spindle motors should be started sequentially using of the following procedures.

Table 5.8 Setting contents (Check item) No. 1 SCSI ID Setting check list (NP model only) Pin pair on CN2 Check Remarks 1/2 (SCSI ID = __) Upper bus (DB 8 to 15 PI) not connected 3/4 5/6 7/8 5.4.
5.5 Connecting Cables Connect the HDD and system with the following cables. See Section 4.3 for further details of the requirements for HDD connector positions and connecting cables. • • • Power cable SCSI cable External operator panel cable (if required for NP model) The general procedures and notes on connecting cables are described below. Especially, pay attention to the inserting orientation of each cable connector. CAUTION Damage 1.
5.6 Checking Operation after Installation and Preparing the HDDs for Use 5.6.1 Confirming initial operations This section describes the operation check procedures after power is turned on. Since the initial operation of the HDD depends on the setting of the motor start mode, check the initial operation by either of the following procedures.
d) If an error is detected in initial self-diagnosis the LED blinks. In this case, it is recommended to issue the REQUEST SENSE command from the initiator (host system) to obtain information (sense data) for error analysis. IMPORTANT The LED lights during the HDD is executing a command. However, in same commands, the lighting time is only an instant. Therefore, it seems that the LED blinks or the LED remains off. 5.6.

Motor starts by START/STOP command * Executing time: about 60 seconds Figure 5.
(2) Checking at abnormal end a) When sense data can be obtained with the REQUEST SENSE command, analyze the sense data and retry recovery for a recoverable error. Refer to Chapter 5 "Sense Data Error Recovery Methods" of the SCSI Logical Interface Specifications for further details. b) Check the following items for the SCSI cable connection: • • • All connectors including other SCSI devices are connected correctly. The terminating resistor is mounted on both ends of the cable.
b. Format parameter (page code = 3) Specify the number of spare sectors for each cell in the "alternate sectors/zone" field (cannot be changed). (2) FORMAT UNIT command Initialize entire recording surface of the disk with the FORMAT UNIT command. The FORMAT UNIT command initializes entire surface of the disk using the P lists, verifies data blocks after initialization, and allocates an alternate block for a defect block detected with verification.
5.6.4 Setting parameters The user can specify the optimal operation mode for the user system environments by setting the following parameters with the MODE SELECT or MODE SELECT EXTENDED command: • • • • Error recovery parameter Disconnection/reconnection parameter Caching parameter Control mode parameter With the MODE SELECT or MODE SELECT EXTENDED command, specify 1 for the "SP" bit on CDB to save the specified parameter value on the disk.
5. (1) The saved value of the MODE SELECT parameter is assumed as the initial value of each parameter after the power-on, the RESET condition, or the BUS DEVICE RESET message. The initiator can change the parameter value temporary (actively) at any timing by issuing the MODE SELECT or MODE SELECT EXTENDED command with specifying "0" to the SP bit in the CDB. Error recovery parameter The following parameters are used to control operations such as HDD internal error recovery: a.
Notes: 1. The user can arbitrarily specify the following parameters according to the system requirements: • • • • 2. (2) ARRE AWRE TB PER The user also can arbitrarily specify parameters other than the above. However, it is recommended to use the default setting in normal operations.
(3) Caching parameters (page code = 8) The following parameters are used to optimize HDD Read-Ahead caching operations under the system environments. Refer to Chapter 2 "Data Buffer Management" of the SCSI Logical Interface Specifications for further details.
a. Control mode parameters Parameter Default value • QUEUE ALGORITHM MODIFIER • QErr: 5.7 Resume or abort remaining suspended commands after sense pending state 0 (Execution sequence of read/write commands is optimized.) 0 (command is resumed) Dismounting HDDs Since the method and procedure for dismounting the HDD, etc. depends on the locker structure of the system, etc., the work procedures must be determined in consideration of the requirements specific to the system.

CHAPTER 6 DIAGNOSTICS AND MAINTENANCE 6.1 Diagnostics 6.2 Maintenance 6.3 Operation Check 6.4 Troubleshooting 6.5 Packaging This chapter describes diagnostics and maintenance. 6.1 Diagnostics 6.1.1 Self-diagnostics The HDD has the following self-diagnostic function. This function checks the basic operations of the HDD. • • Initial self-diagnostics Online self-diagnostics (SEND DIAGNOSTIC command) Table 6.1 lists the contents of the tests performed with the self-diagnostics.
Brief test contents of self-diagnostics are as follows. a. Hardware function test This test checks the basic operation of the controller section, and contains following test. • • • • RAM (microcode is stored) Peripheral circuits of microprocessor (MPU) Memory (ROM) Data buffer b. Seek test This test checks the positioning operation of the HDD using several seek modes (2 points seek, 1 position sequential seek, etc.).
The HDD does not reply to the SCSI bus for up to 2 seconds after the initial self-diagnostics is started.
b. Reporting result of self-diagnostics and error indication When all specified self-diagnostics terminate normally, the HDD posts the GOOD status for the SEND DIAGNOSTIC command. When an error is detected in the self-diagnostics, the HDD terminates the SEND DIAGNOSTIC command with the CHECK CONDITION status. The initiator should issue the REQUEST SENSE command when the CHECK CONDITION status is posted.
(1) Interface test The operations of the SCSI bus and data buffer on the HDD are checked with the WRITE BUFFER and READ BUFFER commands. (2) Basic operation test The basic operations of the HDD are checked by executing self-diagnosis with the SEND DIAGNOSTIC command (see Subsection 6.1.1). (3) Random/sequential read test The positioning (seek) operation and read operation are tested in random access and sequential access modes with the READ, READ EXTENDED, or VERIFY command.
Electrical shock To avoid shocks, turn off the power before connecting or disconnecting a cable, connector, or plug. - Never touch the HDDs while power-feeding. Take the following precautions to prevent disk drive damage during maintenance and troubleshooting: CAUTION Damage Always ground yourself with a wrist strap connected to ground before handling. ESD (Electrostatics Discharge) may cause the damage to the device.
(4) Service system and repairs Fujitsu has the service system and repair facility for the HDD. Contact Fujitsu representative to submit information for replacing or repairing the HDD.
6.2.4 Tools and test equipment HDD troubleshooting and repair in the field require only standard SCSI tools. No special tools or test equipment are required. This manual does not describe the factory-level tools and test equipment. 6.2.5 Tests This HDD can be tested in the following ways: • • • Initial seek operation check (See Subsection 6.3.1) Operation test (See Subsection 6.3.2) Diagnostic test (See Subsection 6.3.3) Figure 6.1 shows the flow of these tests.
Start Start self-test by turning the power on Test results OK? No Check host system (Table 6.2) Yes Host system normal? Execute an operation test using a host computer or test equipment No Analyze system-related error Yes Replaced or repair HDD Test results OK? No No HDD normal? Yes Yes Continue operation Execute diagnostic test using a host computer or test equipment No Test results OK? Yes Test using voltage or temperature stress Test results OK? No Analyze HDD error (Table 6.
6.3 Operation Check 6.3.1 Initial seek operation check If an error is detected during initialization by the initial seek operation check routine at power-on, the spindle motor of the HDD stops, and then the HDD becomes unusable. For an explanation of the operation check before the initial seek, refer to the Section 5.6. 6.3.2 Operation test While the host computer is processing data, the HDD monitors HDD operation including data processing, command processing, and seek operations.
6.4 Troubleshooting 6.4.1 Outline of troubleshooting procedures This section explains the troubleshooting procedures for HDD errors. Depending on the maintenance level, analyze the error to detect a possibly faulty part (HDD, or HDD part). Full-scale troubleshooting is usually required if the error cause is not known. If the error cause is clear (e.g., abnormal noise in DE or burning of the PCBA), troubleshooting is straightforward. 6.4.
Table 6.2 Item System-level field troubleshooting Recommended work DC power cable Check that the power cable is correctly connected to the disk drive and power supply unit. DC power level Check that the DC voltage is within the specified range (±5%). Check that +5V DC supply is from 4.75 to 5.25V DC. For NC model, check the voltage between pin 36 and 76 of the SCSI connector. For NP model, check the voltage between pin 3 and 4 of the power connector. Check that +12V DC supply is from 11.4 to 12.6V DC.
6.4.3 Troubleshooting at the repair site For maintenance at this level, we recommend additional testing of the HDD and signal checking. The sense data posted from the HDD helps with troubleshooting. This sense data makes the error type clear (functional, mechanical, or electrical error). Chapter 7 error analysis by sense data, and gives supplementary information on finding the error cause (faulty part). Table 6.3 lists how to detect a faulty HDD subassembly.
6.4.4 Troubleshooting with parts replacement in the factory This manual does not cover troubleshooting at the factory level. 6.4.5 Finding possibly faulty parts Finding possibly faulty parts in the field was explained in Subsection 6.4.2. This manual does not cover finding possibly faulty parts at the factory level. 6.5 Packaging When the HDD is returned to Fujitsu, the following methods are recommended. 6.5.1 Single HDD packaging Figure 6.
(1) Put the HDD into FCELL. • At this time, the connector of the HDD is directed to the hinge side of FCELL. • The PCBA is put in the side with the material mark of FCELL. (2) Push from two corners of FCELL on the hinge side previously, push two corners of the opening next, and lock FCELL surely. (3) Put the above unitary packaging (packed in FCELL) into the conductivity bag by securing the cushion. (4) Put the HDD with conductivity bag into the cardboard box.
6.5.2 Multi-box packaging (upper) (lower) Figure 6.3 Multi-box packaging (1) Put the conductivity bag into the milti-box, in addition put the cushion (lower) into the bag. (2) Put unitary packaging (FCELL) in the cushion (lower). • At this time, FCELL is put in the cushion (lower) so that the FCELL opening may become downward. The I/F connector may become upward. • For less than 20 HDDs, insert the HDDs starting from the slot with the smallest number in Figure 6.4.
(5) Put the long desiccant between the cushion (upper) (6) Seal the conductivity bag with the packaging tape (7) Close the cardboard box with the packaging tape (Attach the tape in 'H' figure at the tape.) Figure 6.
