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 hazardous situation likely to result in serious personalinjury if the user does not perform the procedure correctly.
This indicates a hazardous situation could result in personal injury if the
user does not perform the procedure correctly.
This indicates a hazardous situation could result in minor or moderatepersonal injury if the user does not perform the procedure correctly. This
alert signal also indicates that damages to the product or other property,
may occur if the user does not perform the procedure correctly.
This indicates information that could help the user use the product more
efficiently.
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:

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.
Overview and features are described in this chapter, and specifications and power requirement are
described.
The MPG3xxxAT series are a 3.5-inc h hard disk drive with a built-in ATA contro ller. The disk drive is
compact and reliable.
1.1Features
1.1.1Functions and performance
(1)Compact
The disk drive has 1 or 2 disks of 95 mm (3.5 inches) diameter, and its height is 26.1 mm (1 inch).
(2)Large capacity
The disk drive can record up to 20.49 GB (formatted) on one disk using the 48/51 CC2EPRML
recording method and 15 recording z one technology. The M PG3xxxAT series have a formatted
capacity of 10.24 GB to 40.99 GB respectively.
(3)High-speed Transfer rate
The disk drive has an internal data rate up to 49.8 MB/s. The disk drive supports an external data
rate up to 16.6 MB/s (PIO mode 4, DMA mode 2), 66.6 MB/s (ultra DMA mode 4) or 100 MB/s
(ultra DMA mode 5).
C141-E110-03EN1 - 1
(4)Average positioning time
Use of a rotary voice coil motor in the head positioning mechanism greatly increases the
positioning speed. The average positioning time is 9.5 ms (at read).
1.1.2Adaptability
(1)Power save mode
The power save mode feature for idle operation, stand by and sleep modes makes the disk drive
ideal for applications where power consumption is a factor.
(2)Wide temperature range
The disk drive can be used over a wide temperature range (5°C to 55°C).
(3)Low noise and vibration
In Ready status, the noise of the disk drive is only about 3.4 bels (MPG3409AT, Typical Sound
Power per ISO7779 and ISO9296).
1.1.3Interface
(1)Connection to interface
With the built-in ATA interface controller, the disk drive can be connected to an ATA interface of
a personal computer.
(2)Data buffer
The disk drive uses a 512-KB or 2-MB data buffer to transfer data between the host and the disk
media.
In combination with the read-ahead cache system described in item (3) and the write cache
described in item (6), the buffer contributes to efficient I/O processing.
(3)Read-ahead cache system
After the execution of a disk read command, the disk drive automatically reads the subsequent data
block and writes it to the data buffer (read ahead operation). This cache system enables fast data
access. The next disk read command would normally cause another disk access. But, if the read
ahead data corresponds to the data requested by the next read command, the data in the buffer can
be transferred instead.
C141-E110-03EN1 - 2
(4)Master/slave
The disk drive can be connected to ATA interface as daisy chain configuration. Drive 0 is a
master device, drive 1 is a slave device.
(5)Error correction and retry by ECC
If a recoverable error occurs, the disk drive itself attempts error recovery. The 42 bytes ECC has
improved buffer error correction for correctable data errors.
(6)Write cache
When the disk drive receives a write command, the disk drive posts the command completion at
completion of transferring data to the data buffer completion of writing to the disk media. This
feature reduces the access time at writing.

"Disk drive defects" refers to defects that involve repair, readjustment, or replacement. Disk drive
defects do not include failures caused by external factors, such as damage caused by handling,
inappropriate operating environments, defects in the power supply host system, or interface cable.
(2)Mean time to repair (MTTR)
The mean time to repair (MTTR) is 30 minutes or less, if repaired by a specialist maintenance staff
member.
(3)CSS cycle
The number of CSS must be less than 50,000.
C141-E110-03EN1 - 9
(4)Service life
In situations where management and handling are correct, the disk drive requires no overhaul for
five years when the DE surface temperature is less than 48°C. When the DE surface temperature
exceeds 48°C, the disk drives requires no overhaul for five years or 20,000 hours of operation,
whichever occurs first. Refer to item (3) in Subsection 3.3 for the measurement point of the DE
surface temperature.
(5)Data assurance in the event of power failure
Except for the data block being written to, the data on the disk media is assured in the event of any
power supply abnormalities. This does not include power supply abnormalities during disk media
initialization (formatting) or processing of defects (alternative block assignment).
1.8Error Rate
Known defects, for which alternative blocks can be assigned, are not included in the error rate
count below. It is assumed that the data blocks to be accessed are evenly distributed on the disk
media.
(1)Unrecoverable read error
Read errors that cannot be recovered by read retries without user's retry and ECC corrections shall
occur no more than 10 times when reading data of 10
the disk drive's error recovery procedure, and include read retries accompanying head offset
operations.
(2)Positioning error
Positioning (seek) errors that can be recovered by one retry shall occur no more than 10 times in
7
10
seek operations.
1.9Media Defects
Defective sectors are replaced with alternates when the disk is formatted prior to shipment from the
factory (low level format). Thus, the host sees a defect-free device.
Alternate sectors are automatically accessed by the disk drive. The user need not be concerned
with access to alternate sectors.
Chapter 6 describes the low level format at shipping.

CHAPTER 2 DEVICE CONFIGURATION
2.1Device Configuration
2.2System Configuration
2.1Device Configuration
Figure 2.1 shows the disk drive. The disk drive consists of a disk enclosure (DE), read/write
preamplifier, and controller PCA. The disk enclosure contains the disk media, heads, spindle
motors actuators, and a circulating air filter.
Figure 2.1Disk drive outerview
C141-E110-03EN2 - 1
(1)Disk
The outer diameter of the disk is 95 mm. The inner diameter is 25 mm. The number of disks used
varies with the model, as described below. The disks are rated at over 50,000 start/stop
operations.
MPG3102AT, MPG3153AT, MPG3204AT: 1 disk
MPG3307AT, MPG3409AT: 2 disks
(2)Head
The heads are of the contact start/stop (CSS) type. The head touches the disk surface while the
disk is not rotating and automatically lifts when the disk starts.
(3)Spindle motor
The disks are rotated by a direct drive Hall-less DC motor.
(4)Actuator
The actuator uses a revolving voice coil motor (VCM) structure which consumes low power and
generates very little heat. The head assembly at the tip of the actuator arm is controlled and
positioned by feedback of the servo information read by the read/write head. If the power is not on
or if the spindle motor is stopped, the head assembly stays in the specific CSS zone on the disk and
is fixed by a mechanical lock.
(5)Air circulation system
The disk enclosure (DE) is sealed to prevent dust and dirt from entering. The disk enclosure
features a closed loop air circulation system that relies on the blower effect of the rotating disk.
This system continuously circulates the air through the recirculation filter to maintain the
cleanliness of the air in the disk enclosure.
(6)Read/write circuit
The read/write circuit uses a LSI chip for the read/write preamplifier. It improves data reliability
by preventing errors caused by external noise.
(7)Controller circuit
The controller circuit consists of an LSI chip to improve reliability. The high-speed
microprocessor unit (MPU) achieves a high-performance AT controller.
C141-E110-03EN2 - 2
2.2System Configuration
2.2.1ATA interface
Figures 2.2 and 2.3 show the ATA interface system configuration. The drive has a 40-pin PC AT
interface connector and supports the PIO transfer till 16.6 MB/s (PIO mode 4), the DMA transfer
till 16.6 MB/s (Multiword DMA mode 2), the ultra DMA transfer till 66.6 MB/s (Ultra DMA
mode 4), and the ultra DMA transfer till 100 MB/s (Ultra DMA mode 5).

IMPORTANT
HA (host adaptor) consists of address decoder, driver, and receiver.
ATA is an abbreviation of "AT attachment". The disk drive is
conformed to the ATA-5 interface.
At high speed data transfer (PIO mode 3, mode 4, DMA mode 2, ultra
DMA mode 4, or ultra DMA mode 5), occurrence of ringing or
crosstalk of the signal lines (AT bus) between the HA and the disk drive
may be a great cause of the obstruction of system relia bility. Thu s, it is
necessary that the capacitance of the signal lines including the HA and
cable does not exceed the ATA-3 and ATA-4 standard, and the cable
length between the HA and the disk drive should be as short as
possible.
