1 Features The Ultrastar 15K73 series uses high performance sputtered disks, GMR heads, and a rotary type voice coil motor to drive the heads. These features provide high capacity, high speed positioning and high reliability. The Ultrastar 15K73 series uses a SCSI interface for data transfer. Related ANSI Specifications are as follows. ANSI X3.
2 Standards and Related Documents (a) Safety standards It is the user’s responsibility to assure the actual system in which the drive is installed meets the appropriate safety requirements. However, the drive was tested to be in compliance with the following standards: UL 1950 3rd Edition CAN/ CSA C22.

3.2 Environmental conditions and reliability Table 3.
Note 1. Storage capacity does not include spare sector and spare cylinder. Note 2. This is the value in the case that the drive is formatted to 512 Bytes/sector. (1 gigabyte shows 1x109 bytes on this document.) Note 3. Ultrastar 15K73 is formatted to 512 Bytes/sector as the default. If non-512 Bytes/sector is required, customer can change it by re-format of the drive. Note 4. Data transfer rate is degraded with cable or host condition or electrical noise. Note 5.
Note 7. The disk drive orientation for shock test is shown in Figure 4.2. Figure 3.2 Shock test direction Test conditions on shock test are as follows. (1) Operating 147m/s2(15G) (Shock mode: half sine wave 11 ms, Test cycle: 5 times) (2) Non-operating 735m/s2(75G) (Shock mode: half sine wave 11 ms, Test cycle: 5 times) 2450m/s2(250G) (Shock mode: half sine wave 2 ms, Test cycle: 5 times) Note 8. Acoustic noise is measured except for the start, stop and seek operations. Drawing No. Sheet No.
Note 9. Recoverable error is measured at the nominal condition with voltage, temperature and default error recovery parameters. Note 10. The drive should be mounted properly (see section 8). Note 11. MTBF represents a prediction of performance based upon a large statistical sample calculated in accordance with Hitachi's standard procedures. Hitachi does not warrant that the predicted MTBF is representative of any particular unit or group of units comprising a customer base.
4 DC power Interface 4.1 DC Power Requirement The drives are operated on DC power (+5V, +12V) only. No power sequencing is required. The +5 and +12 Volts can be applied in any order. Table 4.1 DC Power Requirement Power supply Voltage tolerance Allowed ripple and noise +5V DC 5.0V +/-5% Less than 150mVp-p (0 - 100kHz) Less than 100mVp-p (100kHz - 10MHz) +12V DC 12.0V +/-5% Less than 150mVp-p (0 - 100kHz) Less than 100mVp-p (100kHz - 10MHz) Note 1.

4.3.2 Spindle Start Selection When multiple disk drives are connected to the same power supply and turned on simultaneously, a large current will be required at power up. In the above case, it is recommended to turn the motors on one by one at intervals in order to minimize 12V line current. This can be done according to the following 3 jumper pin configurations in the case of NW drive: 1.
5 Connecting Methods 5.1 Interface Cable (Daisy Chain) Terminator SCSI interface cable Terminator SCSI bus Ultrastar Ultrastar Ultrastar 15K73 15K73 15K73 DC power power supply cable GND Figure 5.1 Cabling layout (WIDE LVD drive) Note 1. The SCSI bus can accommodate a maximum of 16 units on a WIDE (16-bit) bus, including the host processor, Ultrastar 15K73 units, and other SCSI devices. Note 2.
5.2 Low voltage differential (LVD) mode The NW and NC drives have two different transceivers to allow customer to use it in traditional systems which may use single-ended drivers and receivers, or to use it in low voltage differential (LVD) systems which use LVD drivers and receivers. Their I/O circuits are selectable using the I/O "DIFFSENS" line. When the I/O "DIFFSENS" line is between -0.35V and +0.5V, the drive interface circuits operate single-ended. When "DIFFSENS" is between +0.7V and +1.
6 SCSI Interface 6.1 Summary of SCSI Controller The Ultrastar 15K73 SCSI controller interfaces between the drive and the host computer with the Small Computer System Interface (SCSI). (1) ANSI standard The controller supports the SCSI interface that conforms to the ANSI specifications shown in section 2. (2) Compact design The controller is embedded within the disk drive.
(8) Tagged Command Queuing A maximum of 110 commands can be enqueued to this drive. The drive does not have to connect and disconnect to the host controller even if the SCSI command has been issued successively, so the overhead time of the SCSI bus can be reduced. (9) S.M.A.R.T. (Self - Monitoring, Analysis and Reporting Technology) This function helps predict a failure related to the degradation of the disk drive itself. For users seeking to use the drive as long as possible, S.M.A.R.T.
6.2 Summary of SCSI Commands The SCSI controller supports the group 0,1, and 2 commands listed in Table 6.1 Table 6.

Caution 7.2 Mounting of the drive 1. Mount the drive with four 6-32 UNC screws. (Screw's torque : 0.588 to 0.784 N·m) 2. Mounting holes (A1,A2,B1,B2,B3) are available for mounting.(See figure 8.3) It is recommended that the 4 holes, (A1,A2 or B1,B3 on figure 8.3), be used for mounting to keep the proper space between mounting holes. 3. Maximum penetration of the screw is 3.8 mm. 4. Keep a clearance of 3 millimeters from the PCB parts side and the HDA's upper surface for proper cooling air ventilation.

7.4 Precautions on the off-line test or bench test When the off-line test or bench test is performed the drive should be tightly fixed and cooled. The set-up should be similar to the actual system configuration. 7.5 Cooling of the drive Keep the drive (HDA and PCB) cool by using a FAN. Reliability and life of the drive increases as the temperature is lower. Caution 7.6 Reliability temperature The temperature measurement points and temperature limits are shown below. 1.
Caution 8 Precautions for handling The drive is sensitive to shock, vibration, over voltage, temperature, humidity, corrosive gas, magnetic force and electrostatic discharge. If these forces contact the electrical or mechanical components (magnetic heads, magnetic disks), the drive will break down, degrade, or storage data will be lost. The following handling guidelines are mandatory.
8.4 Other Precautions 8.4.1 Do not loosen the screws or disassemble the drive. 8.4.2 Do not remove the PCB from the drive or swap the PCB with other drives. 8.4.3 Do not solder the wire or other parts on the PCB, or reconstruct the PCB. 8.4.4 Do not remove the sealing tape or label on the HDA. 8.4.5 Turn off the power before removing or installing the DC power cable and SCSI interface cable. Turn off the power before removing or installing the jumper. 8.4.
