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 1x10 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.

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...

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.
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 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.

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"...
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.
Page 21
(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.

Caution 7.2 Mounting of the drive 1. Mount the drive with four 6-32 UNC screws. (Screw's torque : 0.588 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.
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.
Caution 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.
