Task Alert message Page
Installation Damage
Never remove any labels from the HDD or deface them in any way.
High temperature
To prevent injury, never touch the HDD while it is hot. The DE and LSI
become hot during operation and remain hot immediately after turning off the
power.
Damage
Data loss
1. The user must not change the setting of terminals not described in this
section. Do not change setting status set at factory shipment.
2. Do not change the setting of terminals except following setting pins
during the power is turned on.
• Write protect: Pin pair 9/10 of the CN2 setting terminal
3. To short the setting terminal, use the short plug attached when the device
is shipped from the factory.
Damage
1. Make sure that system power is off before connecting or disconnecting
cables.
2. Do not connect or disconnect cables when power is on.(except NC model)
1. Be careful of the insertion orientation of the SCSI connectors. With the
system in which terminating resistor power is supplied via the SCSI cable,
if the power is turned on, the overcurrent protection fuse of the
terminating resistor power supplier may be blown or the cable may be
burnt if overcurrent protection is not provided.
When the recommended parts listed in Table 4.2 are used, inserting the
cables in the wrong direction can be prevented.
2. To connect SCSI devices, be careful of the connection position of the
cable. Check that the SCSI device with the terminating resistor is the last
device connected to the cable.

Installation High temperature
To prevent injury, never touch the HDD while it is hot. The DE and LSI
become hot during operation and remain hot immediately after turning off the
power.
Diagnostics and
Maintenance
Data loss
When the SEND DIAGNOSTIC command terminates with the CHECK
CONDITION status, the initiator must collect the error information using the
REQUEST SENSE command. The RECEIVE DIAGNOSTIC RESULTS
command cannot read out the error information detected in the selfdiagnostics.
Data loss
Save data stored on the HDD to other media before requesting repair. Fujitsu
does not assume responsibility if data is corrupted during servicing or repair.
High temperature
To prevent injury, never touch the HDD while it is hot. The DE and LSI
become hot during operation and remain hot immediately after turning off the
power.
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.
Damage
- Always ground yourself with a wrist strap connected to ground before
handling. ESD (Electrostatics Discharge) may cause the damage to the
device.
- To prevent electrical damage to the HDD, turn the power off before
connecting or disconnecting a cable, connector, or plug.
- Never remove a PCBA.
- Never use a conductive cleaner to clean the HDDs.
- Ribbon cables are marked with a colored line. Connect the ribbon cable
to a cable connector with the colored wire connected to pin 1.
- Never open the HDD for any reason.
Damage
- Never remove any labels from the HDD or deface them in any way.
- Never open the DE for any reason. Doing so will void any warranties.

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.
The flexibility and expandability of the SCSI, as well as the powerful command set of the HDD, allow the
user to construct a high-performance reliable disk subsystem with large storage capacity.
The data format can be changed from the format at factory shipment by reinitializing with the user's
system. Refer to Chapter 6 “Disk Media Management” of the SCSI Logical Interface Specifications for
details.
C141-E270 13
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).
(3) SCSI standard
The HDD provides not only SCSI basic functions but also the following features:
• Arbitration
• Disconnection/Reconnection
• Data bus parity
The SCSI commands can manipulate data through logical block addressing regardless of the
physical characteristics of the HDD. This allows software to accommodate future expansion of
system functions.
(4) 8-bit SCSI/16-bit SCSI
The HDD has 16-bit data bus width (16-bit SCSI), which have the wide transfer function suitable
for SCSI-2. 8-bit data bus is available only with NP model.
See subsection 5.3.2 for details of the bus width setting.
For the ultra SCSI model, number of connectable SCSI devices on the same SCSI bus is varied as
follows.
• 8-bit SCSI: 8 drives max. (option for NP model)
• 16-bit SCSI: 16 drives max.
14 C141-E270
(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. The maximum data transfer rate in synchronous
mode may be limited by the cable length, transmission characteristics of the SCSI bus and the
connected SCSI device number.
(6) Continuous block processing
The addressing method of data blocks is logical block address. The initiator can access data by
specifying block number in a logically continuous data space without concerning the physical
structure of the track or cylinder boundaries.
The continuous processing up to [64K-1] blocks in a command can be achieved, and the HDD can
perform continuous read/write operation when processing data blocks on several tracks or cylinder.
(7) Multi-segment data buffer
The data buffer is 8M bytes. Data is transferred between SCSI bus and disk media through this
data buffer. This feature provides the suitable usage environment for users.
Since the initiator can control the disconnect/reconnect timing on the SCSI bus by specifying the
condition of stored data to the data buffer or empty condition of the data buffer, the initiator can
perform the effective input/output operations with utilizing high data transfer capability of the
SCSI bus regardless of actual data transfer rate of the disk drive.
(8) Cache feature
After executing the READ command, the HDD reads automatically and stores (prefetches) the
subsequent data blocks into the data buffer (Read-ahead caching).
The high speed sequential data access can be achieved by transferring the data from the data buffer
without reaccessing the disk in case the subsequent command requests the prefetched data blocks.
The write cache feature is supported. When this feature is enabled, the status report is issued without
waiting for completion of write processing to disk media, thereby enabling high speed write
processing.
C141-E270 15
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. This feature realizes the high speed processing.
(10) Reserve and release functions
The HDD can be accessed exclusively in the multi-host or multi-initiator environment by using
the reserve and release functions.
(11) Error recovery
The HDD can try to recover from errors in SCSI bus or the HDD using its powerful retry
processing. If a recoverable data check occurs, error-free data can be transferred to the initiator
after being corrected in the data buffer. The initiator software is released from the complicated
error recover processing by these error recovery functions of the HDD.
(12) Automatic alternate block reassignment
If a defective data block is detected during read or write the HDD can automatically reassign its
alternate data block.
(13) Programmable data block length
Data can be accessed in fixed-block length units. The data block length is programmable, and can
be specified at initializing with a multiple of four within the range of 512 to 528 bytes.
IMPORTANT
Error rate increase
1. The HDD format at factory shipment is generally 512 byte.
2. The Recoverable Error of the drive might increase when the
format would be modified from 512 bytes to the following values:
516 bytes, 520 bytes, 524 bytes, and 528 bytes.
3. The Recoverable Error referred in 2) is sense data (1-13-xx).
16 C141-E270
(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.
(16) Large capacity
A large capacity can be obtained from the HDDs by dividing all cylinders into several partitions
and changing the recording density on each partition (constant density recording). The disk
subsystem with large capacity can be constructed in the good space efficiency.
(17) Start/Stop of spindle motor
Using the SCSI command, the host system can start and stop the spindle motor.
(18) Diagnosis
The HDD has a diagnostic capability which checks internal controller functions and HDD
operations. Also, for early detection of and recovery from the errors on the disk, the HDD has a
function for periodically implementing a full scan of the disk.
(19) Low power consumption
By using highly integrated LSI components, the power consumption of the HDD is very low, and
this enables the unit to be used in wide range of environmental conditions.
(20) Low acoustic noise
The acoustic noise level is low; approx. 3.6 Bels at Idle. This makes it ideal for office use.
(21) Microcode downloading
The HDD implements the microcode download feature. This feature achieves easy
maintainability of the HDD and function enhancing.

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. The motor speed is controlled by a
feedback circuit using the counter electromotive current to precisely maintain of the specified
speed.
(4) Actuator
The actuator, which uses a rotary voice coil motor (VCM), consumes little power and generates
little heat. The heads at the end of the actuator arm are controlled and positioned via feedback of
servo information in the data.
The heads are positioned on the ramp when the power is off or the spindle motor is stopped.
(5) Air circulation (recirculation filter, breather filter)
The disk enclosure (DE) configures a clean room to keep out particle and other contaminants.
The DE has a closed-loop air recirculation system. Using the movement of the rotating disks, air
is continuously cycled through a filter. This filter will trap any particle floating inside the
enclosure and keep the air inside the DE contaminant free. To prevent negative pressure in the
vicinity of the spindle when the disks begin rotating, a breather filter is attached. The breather
filter also equalizes the internal air pressure with the atmospheric pressure due to surrounding
temperature changes.
(6) Read/write circuit
The read/write circuit utilizes a read channel mounted with a head IC that supports high-speed
transmission and an MEEPRML (Modified Enhanced Extended Partial Response Maximum
Likelihood) modulation/demodulation circuit in order to prevent errors being triggered by external
noise and to improve data reliability.
(7) Controller circuit
The controller circuit uses LSIs to increase the reliability and uses a high speed microprocessing
unit (MPU) to increase the performance of the SCSI controller.

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.

C141-E270 19
(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.
Using disconnect/reconnect function, concurrent input/output processing is possible on multi-
SCSI devices.
(2) Addressing of peripheral device
Each SCSI device on the bus has its own unique address (SCSI ID:#n in Figure 1.1). For
input/output operation, a peripheral device attached to the SCSI bus that operates as target is
addressed in unit called as logical unit. A unique address (LUN: logical unit number) is assigned
for each logical unit.
The initiator selects one SCSI device by specifying that SCSI ID, then specifies the LUN to select
the peripheral device for input/output operation.
The HDD is constructed so that the whole volume of disk drive is a single logical unit, the
selectable number of SCSI ID and LUN are as follows:
• SCSI ID: 8-bit SCSI:Selectable from 0 to 7 (option for NP model, switch selectable)
16-bit SCSI:Selectable from 0 to 15 (switch selectable)
• LUN: 0 (fixed)
