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.
This indicates a hazarous situation could result in personal injury if the
user does not perform the porocedure correctly.
This indicates 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 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:
(Example)
IMPORTANT
HA (host adapter) consists of address decoder, driver, and receiver.
ATA is an abbreviation of "AT attachment". The disk drive is
conformed to the ATA-4 interface
The main alert messages in the text are also listed in the “Important Alert Items.”

Overview and features are described in this chapter, and specifications and power requirement are
described.
The MPE3xxxAE series are a 3.5-inch hard disk drive with a built-in ATA controller. The disk drive is
compact and reliable.
1.1 Features
1.1.1 Functions and performance
(1) Compact
The disk 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 8.46 GB (formatted) on one disk using the 48/51 EPR4ML
recording method and 15 recording zone technology. The MPE3xxxAE series have a
formatted capacity of 4.33 GB to 17.34 GB respectively.
(3) High-speed Transfer rate
The disk drive has an internal data rate up to 40.7 MB/s. The disk drive supports an external
data rate up to 16.7 MB/s or 66.6 MB/s (ultra DMA mode 4).
C141-E093-01EN 1 - 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).
1.1.2 Adaptability
(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 3.5 bels (MPE3173AE, Typical
Sound Power per ISO7779 and ISO9296).
1.1.3 Interface
(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) 512KB data buffer
The disk drive uses a 512KB 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.
(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.
C141-E093-01EN1 - 2
(5) Error correction and retry by ECC
If a recoverable error occurs, the disk drive itself attempts error recovery. The 40 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.

The mean time between failures (MTBF) is 500,000 POH (power on hours) or more
(operation: 24 hours/day, 7 days/week).
This does not include failures occurring during the first three months after installation.
MTBF is defined as follows:
MTBF= (H)
"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
Total operation time in all fields
number of device failure in all fields
The number of CSS must be less than 40,000.
C141-E093-01EN 1 - 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 3.2 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).
1.8 Error 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
according to 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 107 seek operations.
1.9 Media 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
2.1 Device Configuration
2.2 System Configuration
2.1 Device 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 2.1 Disk drive outerview
C141-E093-01EN 2 - 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 40,000 start/stop
operations.
MPE3043AE: 1 disk
MPE3084AE: 1 disk
MPE3173AE: 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-E093-01EN2 - 2
2.2 System Configuration
2.2.1 ATA 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 16.7 MB/s (PIO mode 4), the DMA
transfer till 16.7 MB/s (Multiword DMA mode 2), and the ultra DMA transfer till 66.6 MB/s
(Ultra DMA mode 4).

IMPORTANT
HA (host adapter) consists of address decoder, driver, and receiver.
ATA is an abbreviation of "AT attachment". The disk drive is
conformed to the ATA-4 interface.
At high speed data transfer (PIO mode 3, mode 4, DMA mode 2 or
ultra DMA mode 4), 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 reliability. Thus, 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.
