To use this product safely
Read and follow all instructions and cautions described in this chapter before using the
drive. It is recommended that this manual is kept at a proper location for quick reference.
The description related to safety in this chapter may be changed without notice.
Influence for environment
Although this product emits electro-magnetic field, it will be found to be in compliance with
the EMI regulations such as VCCI class B, FCC Part 15 class B. However, anything other
than this product, such as an interface cable, is excluded. Therefore, the following cases
require a system side improvement.
(1) Disturbance of operations of other products or equipment
(2) Disturbance caused by other product, such as cabling, to operations of other products
or equipment.
Do not change the condition of the drive, excluding the change admitted by Hitachi.
Violating above-mentioned precautions will void any warranties of the HDD.
Please read and understand the following explanation for safety.
General cautions for safety

careful for the safety by yourself.
0.1.3 Do not convert or change the drive. Convert or change of the drive will void any
warranties.
0.1.4 It is customer’s responsibility to assure the actual system in which the drive is
installed meets the appropriate safety regulation. However the drive itself is found
to be compliance with the following standards:
UL 1950 3rd Edition
CAN/CSA C22.2-M95

Safety cautions for this product
Caution
0.2.1 This product is not authorized for use in life support devices or other applications
which pose a significant risk of personal injury.
0.2.2 Handle the drive with care not to suffer bodily injury caused by hitting the edge of
the frame or accidental dropping of the drive.
0.2.3 Since the drive uses glass media for the disk platter, opening of HDA may cause
bodily injury. Warranty void in case of opened HDA or any broken HDA seals. Do
not open the HDA or break any HDA seals.
0.2.4 Temperature of the drive may become more than 50°C. Handle the drive carefully
not to get burned.
Caution
Caution
Caution
0.2.5 To prevent data from being lost due to an unexpected fatal error, data back up is
required.
0.2.6 If a foreign conductive substa nce (metallic powder, fluid, etc.) adheres to active
metal of the drive (Print pattern, component lead, etc. on Printed Circuit Board
(PCB)), it may cause catastrophic failures. Customer should protect the drive from
the above condition.
0.2.7 Improper insertion of connector or wrong jumper setting may cause catastrophic
failures. Referring to this manual prior to the connector insertion or jumper setting
can help insure correct insertion.
0.2.8 Follow the environmental conditions and power requirement described in this
manual. If violating these specifications, the drive failure may occur.
0.2.9 Protect the drive against Electro Static Discharge (ESD) during handling.
0.2.10 If storage period becomes long after unpacking, supply power to the drive and
rotate the disks 8 minutes or more. This operation shall be executed every 3
months.

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.
Interface specifications for the Ultrastar 15K73 are found in the companion manual:
" Hitachi 3.5 inch Magnetic Disk Drive Reference Manual for Ultrastar 15K73
(SCSI Interface Specification) ".

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. These specifications are typical under the following conditions:
1. Voltage is 5.0V/12.0V as measured on the edge of drive connector.
2. Surface temperature of HDA is 40°C.
If SCSI commands are issued during start-up (like TEST UNIT READY or
REQUEST SENSE) in less than 10 ms intervals, then the start-up time may be
extended.

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. The actual
failure rates will vary from unit to unit. Surface temperature of HDA is
50°C or less.
A failure defined by MTBF calculation is any event that requires repair or
replacement of HDD.
