1.0 DESCRIPTION AND FEATURES

1.1 General Description

HGST Travelstar 2.5 inch hard drives combine a high performance 7200 RPM spin speed, 32 MB cache and SATA 6 Gb/s interface for the ultimate in power computing for notebooks.

1.2 Product Features

 Serial ATA (SATA) — Serial ATA (SATA) is the next generation bus interface for

2.5-inch hard drives. It is designed to replace Parallel ATA, and has many advantages including increased transfer rate, improved signal integrity, enhanced data protection, and hot plug support.

 Advanced Format (AF) — Technology adopted by HGST and other drive manufacturers to

increase media format efficiencies, thus enabling larger drive capacities.

 Perpendicular Magnetic Recording (PMR) — With PMR technology the magnetization of

each data bit is aligned vertically to the spinning disk, rather than longitudinally as has been the case in hard drive technology for decades. This enables more data on a given disk than is possible with conventional longitudinal recording, and provides a platform for future expansion of hard drive densities.

 Reduced Power Spinup (RPS) — HGST’s optimized start up feature specifically designed for

the external hard drive and Consumer Electronics (CE) market. Specific focus for RPS is to minimize the duration and magnitude of the peak power consumption from the hard drive.

 System-on-Chip - The System-on-Chip (SOC) is the foundation for HGST's next generation

electronics and firmware architecture. The native SATA SOC lowers component count by integrating a hard disk controller, high performance processor, high speed execution SRAM, and read channel in a 128-pin package.

 S.M.A.R.T. Command Transport (SCT) — The SCT Command Transport feature set provides

a method for a host to send commands and data to a device and for a device to send data and status to a host using log pages.

 Reliability Features Set-Data Lifeguard™ — Representing HGST's ongoing commitment to

data protection, Data Lifeguard includes features that enhance the drive’s ability to prevent data loss. Data Lifeguard data protection utilities include thermal management, an environmental protection system, and embedded error detection and repair features that automatically detect, isolate, and repair problem areas that may develop over the extended use of the hard drive. With these enhanced data reliability features, the drive can perform more accurate monitoring, error repair, and deliver exceptional data security.

 Hot Plug Support — SATA supports hot plugging (also known as “hot swapping”), the ability

to swap out a failed hard drive without having to power down the system or reboot. This capability contributes to both data availability and serviceability without any associated downtime, making it a critical feature for extending SATA into enterprise applications.

 Active LED Status — These drives support external LED requirements. It provides an activity

LED output which is ON during command execution and OFF otherwise.

 Fluid Dynamic Bearings (FDB) — Bearing design that incorporates a layer of high-viscosity

lubricant instead of ball bearings in the hard drive spindle motor. As an alternative to conventional ball bearing technology, FDB designs provide increased non-operational shock resistance, speed control, and improved acoustics.

 Staggered Spin-Up — Native SATA feature that allows the system to control whether the drive

will spin up immediately or wait until the interface is fully ready.

HGST Hard Disk Drive Technical Reference Manual

 CacheFlow™ —HGST’s unique, multi-generation caching algorithm evaluates the way data is

read from and written to the drive and adapts “on-the-fly” to the optimum read and write caching methods. CacheFlow minimizes disk seek operations and overheads due to rotational latency. CacheFlow supports sequential and random write cache. With write cache and other CacheFlow features, the user can cache both read and write data. The cache can hold multiple writes and collectively write them to the hard drive.

 48-bit Logical Block Addressing (LBA) — HGST SATA drives support both 48-bit and 28-bit

LBA and CHS-based addressing. LBA is included in advanced BIOS and operating system device drivers and ensures high capacity disk integration.

 Power Management — HGST SATA drives support the ATA and Serial ATA power

management command set, allowing the host to reduce the power consumption of the drive by issuing a variety of power management commands.

 Automatic Defect Retirement — If the HGST SATA drive detects a defective sector while

reading, writing, or performing offline data collection, it automatically relocates the sector without end-user intervention.

 Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) — S.M.A.R.T. enables a

drive’s internal status to be monitored through diagnostic commands at the host level and during offline activities. S.M.A.R.T. devices employ data analysis algorithms that are used to predict the likelihood of some near-term degradation or fault conditions. When used with a S.M.A.R.T. application, the drive can alert the host system of a negative reliability status condition. The host system can then warn the user of the impending risk of data loss and recommend an appropriate action.

 ATA Security — HGST SATA drives support the ATA Security Mode Feature set. The ATA

Security Mode feature set allows the user to create a device lock password that prevents unauthorized hard disk access even if the drive is removed from the host computer. The correct password must be supplied to the hard drive in order to access user data. Both the User and Master Password features are supported, along with the High and Maximum security modes. The Master Password Revision code is also supported.

Advanced Format (AF) technology is adopted by HGST and other drive manufacturers to increase media format efficiencies, thus enabling larger drive capacities.

In Advanced Format, each physical sector is composed of eight 512 byte logical sectors, totaling 4096 bytes. HGST is shipping Advanced Format drives as 512 Byte Emulated Devices until full operating system support for the Advanced Format host interface is available. 512 Byte Emulated Device drives are backward compatible with 512 byte sector accesses.

3.3 Perpendicular Magnetic Recording (PMR)

In perpendicular magnetic recording (PMR), the magnetization of each data bit is aligned vertically to the spinning disk, rather than longitudinally as has been the case in hard drive technology for decades. In longitudinal recording, as the bits become smaller and closer together, they experience an increasing demagnetizing field, much like two bar magnets that are placed end-to-end repel one another. A property of the media called coercivity must be increased to counteract the demagnetization to keep the bits stable under thermal fluctuations; otherwise data corruption may occur over time. Higher media coercivity has pushed the recording head write field to the limit of known materials.

In perpendicular recording, the adjacent bits attract instead of repel (as with bar magnets placed side by side,) creating more thermally stable bits. In addition, the media contains a magnetically soft underlayer (SUL) beneath the recording layer. This SUL allows a larger effective write field, thus higher coercivity media, enabling further increases in density. Lastly, because of the vertical orientation of the bits, the PMR recording layer tends to be thicker than that used for longitudinal recording, providing increased signal for the read heads. All of these benefits enable HGST engineers to reliably pack more data on a given disk than is possible with conventional longitudinal recording.

HGST Hard Disk Drive Technical Reference Manual

3.4 Reduced Power Spinup (RPS)

Applications for 2.5-inch hard drives include USB external hard drives, notebook systems, and Consumer Electronics (CE). Due to the fact that many of these applications are portable in nature, an option for limiting startup current levels and increasing spinup speed is necessary.

To address this requirement, HGST has developed Reduced Power Spinup (RPS) mode. RPS-enabled drives use minimal power consumption during spin up, allowing a greater range of compatibility with various systems and cables in the marketplace.

RPS mode is set via jumper. See figure 5-4 more information.

Figure 3-1. RPS Spinup Profile

3.5 System-on-Chip (SOC)

The System-on-Chip (SOC) is the foundation for HGST's next generation electronics and firmware architecture. The native SATA SOC lowers component count by integrating a hard disk controller, high performance processor, high speed execution SRAM, and read channel in a 128-pin package. The processor has a 5-stage pipeline which can execute instructions in a single cycle and a DSP engine for enhanced operations. The SOC has on-chip tightly coupled memory for high speed code and data execution that maximizes the processing bandwidth for timing critical operations. It has a high performance disk controller that incorporates maximum flexibility, modularity, performance, and low power consumption. The read/write channel has advanced detection capabilities for highdensity drives.

3.6 S.M .A.R .T. C om ma nd T ra nsp or t (S CT )

The SCT Command Transport feature set provides a method for a host to send commands and data to a device and for a device to send data and status to a host using log pages. Standard ATA commands may be interspersed with SCT commands, but SCT commands cannot be nested. SCT commands that do not require a subsequent data transfer operation are not interspersed with any ATA commands or each other.

The SCT Command Transport feature set provides a method for a host to send commands and data to a device and for a device to send data and status to a host using log pages. This capabilitility is used to pass commands through a driver interface or a bridge where new or unknown commands may be filtered and not passed to the drive. SCT is also used for issuing commands that require more than 8 parameter bytes. ATA8-ACS provides detailed information on the usage and capabilities of SCT. The SCT feature set includes the following command:

 Temperature Reporting

3.6.1 Temperature Reporting

The SCT Temperature Reporting (SCT TR) feature allows a host system to access temperature information in the drive. This information can been used to control fans or adjust the usage of various system components to keep the drive within its normal operating temperature. Applications include Enterprise, Laptop, Desktop and Consumer Electronics. SCT TR reports the maximum and minimum sustained operating limits, warning level limits, and drive damage limits. In addition to reporting the limits, SCT TR returns the current drive temperature (a temperature history which the host can use to predict heating or cooling trends) and the maximum temperature acheived during the lifetime of the drive as well as the highest temperature achieved since the power was applied to the drive. Detailed information on this capability can be found in ATA8-ACS.

HGST Hard Disk Drive Technical Reference Manual

3.7 Reliability Features Set

3.7.1 Data Lifeguard™

Representing HGST's ongoing commitment to data protection, Data Lifeguard includes features that enhance the drive’s ability to prevent data loss. Data Lifeguard data protection utilities include thermal management, an environmental protection system, and embedded error detection and repair features that automatically detect, isolate, and repair problem areas that may develop over the extended use of the hard drive. With these enhanced data reliability features, the drive can perform more accurate monitoring, error repair, and deliver exceptional data security.

This self-tuning feature is performed during offline data collection scan. All user sectors on the hard drive are scanned during times of no activity from the host. Any sector determined to be written poorly (e.g., off-track), or that is difficult to recover (e.g., because of a developing media defect or thermal asperity), is marked for repair. Data Lifeguard actively guards your data, even if S.M.A.R.T. operations are disabled.

All HGST drives are defect-free and low-level formatted at the factory. After prolonged use, any drive, including a HGST drive, may develop defects. If you continue receiving data errors in any given file, use the Data Lifeguard Diagnostics utility to recover, relocate and rewrite the user data to the nearest spare sector and maintain a secondary defect list.

CAUTION:As with all format utilities, some options in the Data Lifeguard Diagnostics

utility will overwrite user data.

3.7.2 Thermal Management

The drive is designed with Thermal Management features for high reliability.

 State-of-the-art mechanical design—Mechanical design is optimized to reduce the drive’s

temperature. State-of-the-art thermal dissipation and windage design is employed.

 Closed loop servo management—Thermal management monitors the drive temperature and

can control servo operations to maintain a stable operating temperature under high temperature conditions. This is a closed loop servo and thermal control system.

 S.M.A.R.T. HDA Temperature Attribute—The S.M.A.R.T. HDA Temperature Attribute is

supported.

 Ducted airflow—Provides protection to the Read/Write element from heated air.

1 Default shipping configuration has Data Lifeguard feature disabled for power management

optimization.

HGST Hard Disk Drive Technical Reference Manual

3.7.3 Internal Environmental Protection System

This system protects the inside environment of the drive from contamination. System features include:

 Filtration System to ensure fast clean-up times

 Directed airflow to maximize mechanical cooling

 Increase casting surface area to maximize cooling

 Ducted air flow to protect read/write elements from heated air

 Breather filter located at low pressure area

 Enhanced heat dissipation

3.7.4 Recoverable Errors

A sector marked for repair is written back to the same location. The sector is then read several times to be sure that it was written correctly and that there is no media damage at its location (sector test). If the sector does not easily and consistently read correctly, the sector is then relocated with original data.

3.7.5 Unrecoverable Errors

If an unrecoverable error is found during the offline scan, the sector is marked. Future reads from this location will continue to perform full error recovery. However, the next write to this location will perform a sector test to be sure the media is not damaged, and the sector relocated if the sector test fails.

3.7.6 Self Test

Self Test is a quick way to determine the operation status of a drive. The following Self Tests are supported:

 Quick Test: Completes in less than two minutes.

 Extended Test: Tests all the critical subsystems of the drive.

 Conveyance Test: Quickly identifies issues caused by handling damage.

 Selective Test: Scans host-defined sections of the drive.

The test may be run to completion or be performed as a background task as the drive processes other commands from the host. The host may then poll the drive for runtime status and test results. Since the test is embedded in the drive’s firmware, it is always available, requires no installation and can be faster and more effective than a software-based drive test.

3.7.7 ATA Error Logging

ATA Error Logging provides an industry standard means to record error events and supporting information that is then accessible by the host. The event record includes the exact command that caused the failure, the response of the drive, the time of the event and information about the four commands immediately prior to the errant command. Error Logging can reliably and quickly determine whether a system problem is the result of a hard drive failure or other component malfunction. Error Logging retains total error count for the life of the drive and complete records for the last five errors.

3.7.8 Defect Management

Every HGST drive undergoes factory-level intelligent burn in, which thoroughly tests for and maps out defective sectors on the media before the drive leaves the manufacturing facility. Following the factory tests, a primary defect list is created. The list contains the cylinder, head, and sector numbers for all defects.

HGST Hard Disk Drive Technical Reference Manual

Defects managed at the factory are sector slipped. Grown defects that can occur in the field are mapped out by relocation to spare sectors on the inner cylinders of the drive.

3.7.9 Automatic Defect Retirement

The automatic defect retirement feature automatically maps out defective sectors while reading or writing. If a defective sector appears, the drive finds a spare sector.

The following item is specific to automatic defect retirement on writes (write auto-relocation):

 Data is always written to disk (using automatic defect retirement if required) and no error is

reported.

The following item is specific to automatic defect retirement on reads (read auto-relocation):

 When host retries are enabled, the drive will internally flag any unrecoverable errors (DAMNF

or ECC). This flagging allows subsequent write commands to this location to relocate the sector only if the sector test fails.

3.7.10 Error Recovery Process

The drive has the following means of Error Recovery:

 One-the-Fly Recovery: Using LDPC's internal recovery mechanism with Global and Local

Iteration for Error Recovery and Correction. This recovery is real time and does not require any additional re-reads for the correction.

 Simple Firmware Assist Recovery: Single variable re-reads involving off-track recoveries and

synch mark retires.

 Extended Firmware Assist Recovery: This retry procedure will step through a combination of

positive/negative track offsets and VGA DAC manipulations to recover the data. In addition, further retries will also involve Low Pass Filter (FIR) manipulations, Timing recovery, and Synch Error Recoveries deeper into the retry process. Furthermore, in specific retry steps Hardware assist is also involved for Extended Retry involving more modification of FIR filters & Erasure Sweep.

 LDPC Erasure Sweep Correction: This step sweeps the entire data stream with a Erasure

Length and a Sliding Window, both programmable, to maximize the correction capability.

When an extended retry operation is successful, the controller continues with the command. The controller clears any changes during the F/W Assist Recovery before commencing to the next operation.

3.8 Hot Plug Support

SATA supports hot plugging (also known as “hot swapping”), the ability to swap out a failed hard drive without having to power down the system or reboot. This capability contributes to both data availability and serviceability without any associated downtime, making it a critical feature for extending SATA into enterprise applications.

HGST SATA drives support hot plugging only in systems where a SATA hard drive storage backplane is used.

The Serial ATA revision 2.5 specification requires staggered pins for both the hard drive and drive receptacles. Staggered pins mate the power signals in the appropriate sequences required for powering up the hot plugged device. These pins are also specified to handle in excess of the maximum allowed inrush current that occurs during drive insertion. SATA-compliant devices thus need no further modification to be hot pluggable and provide the necessary building blocks for a robust hot plug solution, which typically includes:

 Device detection even with power downed receptacles (typical of server applications).

 Pre-charging resistors to passively limit inrush current during drive insertion.

HGST Hard Disk Drive Technical Reference Manual

 Hot plug controllers to actively limit inrush current during drive insertion.

HGST Hard Disk Drive Technical Reference Manual

3.9 Active LED Status

The drive supports external LED requirements. It provides an activity LED output which is ON during command execution and OFF otherwise.

The drive strength of this open drain drive active signal is that it can sink 12mA to 0.4V Max. It is 5V tolerant, meaning that the external LED may be driven from +5V or +3.3V so long as the Host system provides a series resistor to limit the LED current to the lower of 12mA or the rated operating current of the LED. As an example with +5V and a 2 volt forward drop across a 10mA LED, a 300 Ohm 5% 1/16W resistor would be suitable. In the case of a 3.3V supply for the same LED, the resistor would be 130 Ohm 5% 1/16W.

The pin corresponding to P11 shall be used for Active LED (see “Device Pin Connector Pin Definitions” on page 19).

3.10 Fluid Dynamic Bearings (FDB)

Bearing design that incorporates a layer of high-viscosity lubricant instead of ball bearings in the hard drive spindle motor. As an alternative to conventional ball bearing technology, FDB designs provide increased non-operational shock resistance, speed control, and improved acoustics.

3.11 Staggered Spinup and Activity Indication (SATA Pow er Pin 11)

SATA device power connector pin 11 (see “Standard Factory Connectors” on page 19) is defined as a means by the host to DISABLE staggered spinup and it may also be used by the device to provide the host with an activity indication. According to the SATA II specs, "Staggered Spin-up Disable and Activity Signal shall not be enabled at the same time."

3.11.1 Staggered Spinup

When multiple disks are installed in an enclosure, it is desirable to provide a simple mechanism by which a subsystem controller can sequence hard drive initialization to minimize the current load presented during power up. Staggered spinup provides this mechanism by preventing the hard drives from spinning up until after successful PHY initialization (i.e., after PHY enters DP7:DR_Ready state).

Staggered spinup is only applicable during initial power-up. If a drive is spun down using ATA commands—as a result of having been placed in Standby or Sleep power modes, for example—the drive shall spin up following the rules that govern spinup from low power modes described in ATA/ATAPI-6 or later.

3.11.2 Activity Indication

The host controller through SATA power pin 11 may access storage device status and activity. The signal provided by the device for activity indication is a low-voltage low-current signal. It is not suitable for directly driving an LED. A buffer circuit external to the device must be employed to drive the LED. The activity signal is based on an open-collector or open-drain active low driver. The device shall tolerate the activity signal being shorted to ground.

3.12 CacheFlow ™

CacheFlow is HGST’s unique, multi-generation disk caching system. It incorporates read cache with write cache.

HGST designed CacheFlow to obtain maximum performance with today’s most popular operating systems and applications. CacheFlow increases performance over prior caching algorithms by increasing the number of times that requested data is in the cache. This reduces the number of host commands that require actual media access thereby improving overall drive performance.

HGST Hard Disk Drive Technical Reference Manual

Typical applications perform a variety of access patterns, such as random, sequential, and repetitive. CacheFlow is designed to dynamically adapt to the changes in access patterns that occur during the course of application execution.

Random mode is the default operational mode for CacheFlow. Once CacheFlow detects a sequential access pattern, it leaves random mode. CacheFlow also performs predictive read operations to increase the probability that data requested in future commands already exists in the cache.

CacheFlow partitions the buffer into multiple segments to allow for the fact that applications may access multiple non-contiguous areas on the disk. CacheFlow tracks the amount of valid data in each segment and controls the deallocation of segments to maximize drive performance.

3.12.1 Write Cache

CacheFlow is designed to improve both single and multi-sector write performance by reducing delays caused by seek time and rotational latency.

The write cache adaptively detects random and sequential access patterns during application execution.

If a defective sector is found during a write cache operation, that sector is automatically relocated before the write occurs.

3.12.2 Read Cache

CacheFlow implements a multiple segment read cache. Cache segments are assigned to read commands as they are received from the host.

Each read segment consists of pre and post read sectors in addition to the host-requested sectors. This maximizes the amount of cache data in the drive’s buffer, thereby increasing the likelihood of cache hits and improving overall performance.

3.12.3 48-bit Logical Block Addressing (LBA)

The 48-bit Address feature set allows devices with capacities up to approximately 281 tera sectors or approximately 144 peta bytes. In addition, the number of sectors that may be transferred by a single command are increased by increasing the allowable sector count to 16 bits.

3.13 Power Management

The drives support the ATA power management commands that lower the average power consumption of the hard drives. For example, to take advantage of the lower power consumption modes of the drive, an energy efficient host system could implement a power management scheme that issues a Standby Immediate command when a host resident disk inactivity timer expires. The Standby Immediate command causes the drive to spin down and enter a low-power mode. Subsequent disk access commands would cause the drive to spin up and execute the new command.

To avoid excessive wear on the drive due to the starting and stopping of the HDA, set the host’s disk inactivity timer to no shorter than ten minutes.

HGST Hard Disk Drive Technical Reference Manual

The drives also support the SATA power management feature that lowers the average power consumption of the SATA interface.

3.14 Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.)

S.M.A.R.T. helps you monitor a drive’s internal status through diagnostic commands at the host level.

The drive monitors Read Error Rate, Start/Stop Count, Re-allocated Sector Count, Seek Error Rate, Power-on Hours Count, Spin-up Retry Count, Drive Calibration Retry Count, Drive Power Cycle Count, Offline Scan Uncorrectable Sector Count, Ultra ATA CRC Error Rate, Multi-zone Error Rate, Spin-up Time, Relocation Event Count, and Current Pending Sector Count. The hard drive updates and stores these attributes in the reserved area of the disk. The drive also stores a set of attribute thresholds that correspond to the calculated attribute values. Each attribute threshold indicates the point at which its corresponding attribute value achieves a negative reliability status.

3.15 Security Mode

The Security Mode feature set allows the user to create a device lock password that prevents unauthorized hard drive access even if the drive is removed from the computer.

3.15.1 Master and User Passwords

The manufacturer/dealer can set a master password using the Security Set Password command, without enabling the device lock function. The user password should be given or changed by a system user.

Master Password Identifier is supported and set to a default value of 00FE. If a Master Password is set via a Security Set Password Command, a valid Master Password Revision code value of 0001h – 00FEh must be used. A Master Password Identifier of 0000h is ignored.

When the master password is set, the drive does not enable the device lock function. When the user password is set, the drive enables the device lock function, and the drive is locked after the next power on reset or hard reset.

3.15.2 Security Levels

High - If High level security is set and the user password is forgotten, the master password can be used to unlock the drive and access the data.

Maximum - If Maximum level security is set and the user password is forgotten, data access is impossible. Only the master password with a Security Erase Unit command can unlock the drive when the device lock function is enabled and the user password has been forgotten. When the Security Erase Unit command is used to unlock the drive, all user data is erased.

HGST Hard Disk Drive Technical Reference Manual

5.0 INSTALLATION AND SETUP PROCEDURES

Hard drives are precision instruments that must be handled with care to prevent damage. It is important to understand that drives are typically damaged due to electrostatic discharge (ESD), pressing on the top cover, rough handling, or shock and vibration. Also refer to the HGST 2.5-inch Hard Drive Handling poster (part number 2378-701047) for details on drive handling.

Important: If your system does not support hot plugging (see “Hot Plug Support” on page 28), it must be turned off and unplugged before installing your hard drive.

5.1 Unpacking

5.1.1 Handling Precautions

HGST products are designed to withstand normal handling during unpacking and installation. Take care to avoid excessive mechanical shock, pressing on the top cover, or electrostatic discharge (ESD) which can permanently damage the hard drive and void the warranty. Hard drives are typically damaged because of ESD, rough handling, or shock and vibration.

Figure 5-1. Drive Handling Precautions

Hard drives are delicate, precision instruments and should be handled with care at all times. Hard drives are typically damaged by rough handling, shock, vibration, and electrostatic discharge (ESD).

Handle the Drive ONLY by its Sides

DO NOT Press on the Top Cover of the Drive

To avoid ESD problems, wear a properly grounded wrist strap when handling the hard drive. Articles of clothing generate static electricity. Do not allow clothing to come in direct contact with the hard drive or circuit board components.

When the drive is not in its shipping container or installed in its proper host enclosure, it must remain in the antistatic bag. To prevent damage, do not unpack your drive until you are ready to install it.

CAUTION:To avoid damage to internal drive components, do not apply a load greater than

2.6 lbf to a circular 10 mm diameter area anywhere on the top cover. Chassis design should allow for sufficient clearance and support to prevent loads from being transferred to the drive top cover.

HGST Hard Disk Drive Technical Reference Manual

5.1.2 Inspection of Shipping Container

Carefully examine the container for obvious shipping damage, such as: holes, signs of crushing, or stains. Notify the carrier and your HGST representative if you observe any shipment damage. Always move the shipping container in the upright position indicated by the arrows on the container.

5.1.3 Removal From Shipping Container

Remove the drive from the shipping container only for inspection or installation. Carefully open the box. When removing the drive from the box, follow these precautions:

 Grasp the drive by the sides only; avoid touching the circuit board components.

 Gently place the drive on its antistatic bag on a clean, level, grounded work area.

 Do not stack drives or stand the drive on its edge.

CAUTION:When removing the drive from the shipping container, be careful not to drop it.

Dropping the drive can severely damage the head disk assembly or printed circuit board.

5.1.4 Removal From Static Shielding Bag

Before removing the drive from its static shielding bag:

 Make sure that your work station is properly grounded.

 Wear a properly grounded wrist strap with good skin contact.

 Avoid contact with any component on the printed circuit board.

Figure 5-2. Hard Drive Removal From Static Shielding Bag

After attaching your wrist strap, gently remove the drive from the static shielding bag.

 Handle the drive by the sides only; avoid touching the printed circuit board.

 Handle the drive with the printed circuit board facing downward during installation.

 The unit should not be moved during drive activity.

 The unit is not intended as a portable device.

 Do not attempt to open the drive and service it yourself. Removing the cover may expose you

to harmful electrical voltages and will void the warranty.

 To allow ventilation, do not block the air slots on the underside and rear of the enclosure.

 Do not remove the tape seal or any labels from the drive; this will void the warranty.

5.1.5 Moving Precautions

If you need to move your computer, turn off the power to automatically park the heads. Parking moves the heads to a safe, non-data landing zone where they lock into place. This helps protect the media and the heads from accidental damage due to vibration, moving, or shipping.

HGST Hard Disk Drive Technical Reference Manual

5.2 Bare Drive Handling External Force

Cover stiffness must be sufficient to prevent cover-to-media or cover-to-hub contact when a 2.6 lbf load is applied to a circular 10 mm diameter area anywhere on the cover.

5.3 Mounting Restrictions

Important: Your system must be turned off and unplugged before installing your hard drive.

5.3.1 Orientation

You can mount the hard drive in the X, Y, or Z axis, depending upon the physical design of your system. For best results, mount the drive with all four screws grounded to the chassis. If all four screws are not used, see "Grounding" on page 50.

5.3.2 Screw Type and Screw Length Limitations

The hard drive should be mounted to the chassis using four M3 screws. Recommended screw torque is 5 in-lb. Maximum screw torque is 6 in-lb.

CAUTION: Screws that are too long can damage the hard drive. Hard drive screw penetration

can differ between products depending upon hard drive design. HGST's minimum design criteria is to always meet the SFF 8201 industry standard specification. The industry standard as defined in the SFF 8201, specifies for Side Mounting a maximum of 3 mm screw penetration, and a minimum of 3 threads engagement, for Bottom Mounting a maximum of 2.5 mm screw penetration, and a minimum of 2.5 threads engagement.

HGST Hard Disk Drive Technical Reference Manual

5.3.3 Grounding

For best results, mount the drive with all four screws in the side grounded to the chassis (positions A, B, C, and D below). You must ground the drive with at least one mounting screw.

When mounting the drive in a chassis or system, the chassis or system should never contact the cross-hatched area “E” to prevent electrical shorting of the PCBA or drive. Contact should be limited to the side mounting (A,B,C, and D) or top facing mounting (1,2,3, and 4).

Figure 5-3. Grounding Diagram

Side Mounting – Use four metal screws in A, B, C, and D. If less than four screws are used, remove in this order: C, D, and then B. You must use a screw in position A.

Top face Mounting–Use four metal screws in 1, 2, 3 and 4. If less than four screws are used, remove in this order: 2, 4, and then 3. You must use a screw in position 1.

HGST Hard Disk Drive Technical Reference Manual

5.4 Jumper Settings

It is not necessary to put a jumper shunt on the drive for notebook use. Advanced settings for the drive are as follows:

SSC Mode – Spread spectrum clocking feature. Default setting is disabled.

RPS Mode – RPS feature. Default setting is disabled

Figure 5-4. Jumper Settings

HGST Hard Disk Drive Technical Reference Manual

6.0 MAINTENANCE

The hard drive requires no preventative maintenance and contains no user-serviceable parts. The service and repair of HGST drives can only be performed at a HGST Service Center. Please contact your HGST representative for warranty information and service/return procedures.

Observe the following precautions to prolong the life of the drive:

 Do not attempt to open the sealed compartment of the HGST drive as this will void the warranty.

 Do not lift a HGST drive by the printed circuit board.

 Avoid static discharge when handling a HGST drive.

 Avoid harsh shocks or vibrations.

 Do not touch the components on the printed circuit board.

 Do not obstruct or cover any holes on the drive’s cover. Air must be able to pass through these holes to the

external air filter for normal operation of the drive.

 Observe the environmental limits specified for this product.

 To protect your data, back it up regularly. HGST assumes no responsibility for loss of data. For information

about back-up and restore procedures, consult your operating system manual. There are also a number of utility programs available that you can use to back up your data.

HGST Hard Disk Drive Technical Reference Manual

7.0 GLOSSARY

Active LED Status - HGST SATA drives support external LED requirements. It provides an activity LED output which is ON during command execution and OFF otherwise.

Advanced Format (AF) — Technology adopted by HGST and other drive manufacturers to increase media format efficiencies, thus enabling larger drive capacities.

Annualized Failure Rate (AFR) - A method of measuring failure rates or trends for a group of units at a site. The rates are based on the monthly total number of returned field failure units divided by the total cumulative installed base and multiplied by 12 (to annualize the failure rate).

Automatic Defect Retirement - If defective sectors are found during a read or write, they are automatically mapped out and relocated.

Block - A group of bytes handled, stored, and accessed as a logical data unit, such as an individual file record.

Buffer - A temporary data storage area that compensates for a difference in data transfer rates and/or data

processing rates between sender and receiver.

Data Lifeguard™ — Representing HGST's ongoing commitment to data protection, Data Lifeguard data protection utilities include thermal management, an environmental protection system, and embedded error detection and repair features that automatically detect, isolate, and repair problem areas that may develop over the extended use of the hard drive.

Data Transfer Rate -The rate that digital data is transferred from one point to another, expressed in bits per second or bytes per second.

 Data Transfer Rate to Disk: The internal disk transfer rate in Mbits per second.

 Data Transfer Rate from the Buffer to the Host: Based on the transfer of buffered data in MB per second.

Defect Management -A general methodology of eliminating data errors on a recording surface by mapping out known bad areas of the media.

ECC On-the-Fly -A hardware correction technique that corrects errors in the read buffer prior to host transfer without any performance penalties. These error corrections are invisible to the host system because they do not require assistance from the drive’s firmware.

Error Correction Code (ECC) -A mathematical algorithm that can detect and correct errors in a data field by adding check bits to the original data.

F.I.T. (Functional Integrity Testing) - A suite of tests HGST performs on all its drive products to ensure compatibility with different hosts, operating systems, application programs, and peripherals. This testing must be performed before the product can be released to manufacturing.

Fluid Dynamic Bearings (FDB) - Bearing design that incorporates a layer of high-viscosity lubricant instead of ball bearings in the hard drive spindle motor. As an alternative to conventional ball bearing technology, FDB designs provide increased non-operational shock resistance, speed control, and improved acoustics.

Formatted Capacity - The actual capacity available to store data in a mass storage device. The formatted capacity is the gross capacity minus the capacity taken up by the overhead data required for formatting the media.

Hot Plugging - The ability to swap out a failed hard drive without having to power down the system or reboot.

Latency - The period of time that the read/write heads wait for the disk to rotate the data to an accessible

position.

Logical Address - A storage location address that may or may not relate directly to a physical location. The logical address is usually used when requesting information from a controller. The controller performs a logicalto-physical address conversion and retrieves the data from a physical location in the storage device.

Logical Block Address - An alternative addressing methodology of identifying a given location on an SATA drive that permits disk sizes greater than 528 MB.

Perpendicular Magnetic Recording (PMR) - In PMR, the magnetization of each data bit is aligned vertically rather than longitudinally to the spinning disk. The adjacent bits attract instead of repel (as with bar magnets placed side by side), creating more thermally stable bits.

HGST Hard Disk Drive Technical Reference Manual

PRML (Partial Response Maximum Likelihood) - A read channel using sampled data, active equalization and

Veterbi detection to accurately retrieve the user data off the disk.

Reduced Power Spinup (RPS) — HGST’s optimized start up feature specifically designed for the external hard drive and Consumer Electronics (CE) market. Specific focus for RPS is to minimize the duration and magnitude of the peak power consumption from the hard drive.

RoHS (Restriction of Hazardous Substances) — HGST complies with the Restriction of Hazardous Substances (RoHS) Directive 2002/95/EC of the European Parliament, which is effective in the EU beginning July 1, 2006. RoHS aims to protect human health and the environment by restricting the use of certain hazardous substances in new equipment, and consists of restrictions on lead, mercury, cadmium, and other substances.

Rotational Latency - The amount of delay in obtaining information from a hard drive that can be attributed to the rotation of the disk.

RPM (Revolutions per Minute) - Rotational speed of the media (disk), also known as the spindle speed. Hard drives spin at one constant speed. The slower the RPM, the higher the mechanical latencies. Disk RPM is a critical component of hard drive performance because it directly impacts the rotational latency of the disk transfer rate.

Serial ATA (SATA) - SATA is the next generation bus interface for hard drives. It is designed to replace Parallel ATA, and has many advantages including increased transfer rate, improved signal integrity, enhanced data protection, and hot plugging.

Sector - A 512- or 4K-byte packet of data.

Seek Time - The time it takes for the read/write head to move to a specific block of data on the hard drive. The

average seek time is computed by dividing the time it takes to complete a large number of random seeks by the number of seeks performed.

Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) - A technology to assist the user in preventing possible system down time due to hard drive failure.

S.M.A.R.T. Command Transport (SCT) — The SCT Command Transport feature set provides a method for a host to send commands and data to a device and for a device to send data and status to a host using log pages.

System-on-Chip - The System-on-Chip (SOC) is the foundation for HGST's next generation electronics and firmware architecture. The native SATA SOC lowers component count by integrating a hard disk controller, high performance processor, high speed execution SRAM, and read channel in a 128-pin package.

Unrecoverable Error - A read error that cannot be overcome by an ECC scheme or by rereading the data when host retries are enabled.

Write Cache - A feature in CacheFlow that posts “command complete” prior to completing the actual write.
