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.”

1.9Media Defects

Overview and features are described in this chapter, and specifications and power requirement are described.

The MPE3xxxAT series are a 3.5-inch hard disk drive with a built-in ATA controller. The disk drive is compact and reliable.

1.1Features

1.1.1Functions and performance

(1)Compact

The disk has 1, 2, 3 or 4 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 6.48 GB (formatted) on one disk using the 16/17 EPR4ML recording method and 15 recording zone technology. The MPE3xxxAT series have a formatted capacity of 6.48 GB to 25.68 GB respectively.

(3)High-speed Transfer rate

The disk drive has an internal data rate up to 30.4 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-E077-01EN

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).

1.1.2Adaptability

(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 3.6 bels (MPE3273AT, 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)512-KB 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.

1 - 2

C141-E077-01EN

(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 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.

1.7Reliability

(1)Mean time between failures (MTBF)

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:

Total operation time in all fields

MTBF= number of device failure in all fields (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

The number of CSS must be less than 40,000.

C141-E077-01EN

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).

1.8Error 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 1015 bits. Read retries are executed 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.

1.9Media 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 2.1 Disk drive outerview

C141-E077-01EN

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.

MPE3064AT: 1 disk

MPE3102AT, MPE3136AT: 2 disks MPE3170AT, MPE3204AT: 3 disks MPE3273AT: 4 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 circuilation 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. If inproves 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 contorller.

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 16.7 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 adaptor) 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.
