C141-E045-02EN iii 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-3 interface The main alert messages in the text are also listed in the "Important Alert Items." iv C141-E045-02EN 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.

The MPB3021AT/MPB3032AT/MPB3043AT/MPB3052AT/MPB3064AT are a 3.5-inch hard disk drive with a built-in ATA controller. The disk drive is compact and reliable. 1.1 1.1.1 (1) Features Functions and performance Compact The disk has 1, 2 or 3 disks of 95 mm (3.5 inches) diameter, and its height is 25.4 mm (1 inch). (2) Large capacity The disk drive can record up to 2,162 MB (formatted) on one disk using the 8/9 PRML recording method and 14 recording zone technology. The MPB3021AT, MPB3032AT, MPB3043AT, MPB3052AT and MPB3064AT have a formatted capacity of 2,162 MB, 3,243 MB, 4,325 MB, 5,249 MB and 6,488 MB respectively. (3) High-speed Transfer rate The disk drive has an internal data rate up to 16.71 MB/s. The disk drive supports an external data rate up to 16.7 MB/s or 33.3 MB/s (ultra DMA mode). C141-E045-02EN 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 10 ms (at read). 1.1.2 (1) Adaptability 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 3.8 bels (MPB3064AT, Typical Sound Power per ISO7779 and ISO9296). 1.1.3 (1) Interface 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) 256-KB data buffer The disk drive uses a 256-KB 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. 1-2 C141-E045-02EN (5) Error correction and retry by ECC If a recoverable error occurs, the disk drive itself attempts error recovery. The 18-byte 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. C141-E045-02EN 1-3 1.2 1.2.1 Device Specifications Specifications summary Table 1.1 shows the specifications of the disk drive.

This does not include failures occurring during the first three months after installation. MTBF is defined as follows: Total operation time in all fields number of device failure in all fields 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) 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. C141-E045-02EN 1-9 (4) 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 maximum 126 times 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. 1.9 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. 1 - 10 C141-E045-02EN CHAPTER 2 DEVICE CONFIGURATION 2.1 2.2 Device Configuration 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-E045-02EN 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. MPB3021AT: MPB3032AT: MPB3043AT: MPB3052AT: MPB3064AT: 1 disk 2 disks 2 disks 3 disks 3 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. Figure 2.2 illustrates the configuration of the disks and heads of each model. In the disk surface, servo information necessary for controlling positioning and read/write and user data are written. Numerals 0 to 5 indicate read/write heads. 2-2 C141-E045-02EN MPB3021AT Model MPB3021 Model Spindle Actuator 1 0 MPB3032AT Model MPB3032AT Model Spindle Actuator MPB3043AT Model Model Spindle Actuator 3 2 1 0 2 1 0 MPB3052AT Model MPB3052AT Spindle Actuator MPB3064AT Model Model Spindle 5 Actuator 4 3 2 1 0 4 3 2 1 0 Figure 2.2 Configuration of disk media heads (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 edge 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. C141-E045-02EN 2-3 (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 circulation filter to maintain the cleanliness of the air within the disk enclosure. (6) Read/write circuit The read/write circuit uses a LSI chip for the read/write preamplifier. reliability by preventing errors caused by external noise. It improves data (7) Controller circuit The controller circuit consists of an LSI chip to improve reliability. microprocessor unit (MPU) achieves a high-performance AT controller. The high-speed 2.2 2.2.1 System Configuration ATA interface Figures 2.3 and 2.4 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 (ATA-3, Mode 4), the DMA transfer till 16.7 MB/s (ATA-3, Multiword mode 2), and the ultra DMA transfer till 33.3 MB/s (ATA-4, Ultra DMA mode 2). 2.2.2 1 drive connection Host HA (Host adaptor) Disk drive AT bus (Host interface) Figure 2.3 ATA interface 1 drive system configuration 2-4 C141-E045-02EN 2.2.3 2 drives connection Host HA (Host adaptor) Disk drive #0 AT bus (Host interface) Disk drive #1 ATA interface Note: When the drive that is not conformed to ATA is connected to the disk drive is above configuration, the operation is not guaranteed. Figure 2.4 2 drives configuration 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-3 interface. At high speed data transfer (PIO mode 3, mode 4, DMA mode 2 or ultra DMA mode 2), 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.

Pay attention to the air flow to prevent the DE surface temperature from exceeding 60°C. Provide air circulation in the cabinet such that the PCA side, in particular, receives sufficient cooling. To check the cooling efficiency, measure the surface temperatures of the DE. Regardless of the ambient temperature, this surface temperature must meet the standards listed in Table 3.1.
