DESCRIPTION AND FEATURES

General Description

Western Digital Ultrastar Capac ity Enterprise hard drives offer up to 10 TB capacities and are available with SATA interface. With the highest error tolerance and MTBF of any capacity-optimized drive, Western Digital Ultrastar deliver s the durability and reliability required in tightly packed vibration prone multi-drive systems. The combination of high-capacity, peak performance and robust design make Western Digital Ultrastar drives ideal for heavy workload environments, cloud storage, RAID arrays, external storage arrays, data warehousing, and mining applications.

Product Features

 Serial ATA (SATA) — Serial ATA (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 plug support.

 Time-Limited Error Recovery (TLER) — TLER prevents hard drive error recovery fallout by

limiting the time the drive spends in error recovery, providing increased performance, improved availability, and lower total cost of ownership in RAID arrays.

 Rotary Acceleration Feed Forward (RAFF) — These drives employ RAFF technology to maintain

hard drive performance in high vibration environment s through adap t ive compensat i on of the servo system.

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

data bit is aligned vertically to the sp inning disk, ra ther 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 conventiona l longitudinal recording, a nd provides a p l atform for futur e expansion of hard drive densities.

 IntelliSeek™ — Key product feature that calculates optimum seek speeds to lower power

consumption, noise, and vibration.

 Native Command Queuing (NCQ) — Performance of a random I/O workload can be improved

through intelligent re-ordering of the I/O requests so they read/write to and from the nearest available sectors and minimize the need for additional disk revolutions or head actuator movement. This improvement can be achieved though Native Command Queing (NCQ) , which is supp orted by these hard drives .

 Pre-emptive Wear Leveling (PWL) — This feature provides a solution for protecting the recording

media against mechanical wear. In cases where the drive is so busy with incoming commands that it is forced to stay in a same cylinder position for a long time, the PWL control engine initiates forced seeks so that disk lubricant maintains an even distribution and does not become depleted. This feature ensures reliability for applications that perform a high incidence of read/write operations at the same physical location on the disk.

 MicroFemto Slider — These drives incorporate the next generation of femto slider form factor in

which the read/write head is mounted o n the small, lightweight microfemto slider that all ows the head to move more quickly from track to track on the disk.

 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.

 World Wide Name (WWN) — The World Wide Name (WWN) defined in ATA/ATAPI-7 is a

modification of the IEEE extended unique identifier 64 bit standard (EUI-64) and is comprised of three major components: naming authority, organizationally unique id e ntifie r (OUI) and serial number.

This product’s OUI is 0014EEh.

and written to the drive and adapts “on-the-fly” to the optimum read and write caching method s. 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 disk.

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 impend ing risk of data loss and recommend an appropriate action.

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. This feature varies by drive co nfiguration and may not be avail able on all co nfigurations.

CacheFlow™

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

CacheFlow was designed to obtain maximum performance with today’s most popular operating s yste ms 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.

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 fut ure c ommands already exists in the cache.

CacheFlow partitions the buff e r into multiple segments to allow for the fact that applica tions 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.

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.

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 o verall performance.

Use either the four bottom screws or at least four of the side mounting screws to rigidly suppo rt the drive and prevent vibration. Some adaptor frames may not have the mechanical design structure capable of mounting the drive to meet the specified shock and vibration requirements.

The hard drive itself does not pr ovide electrical isolation between mounting locations and drive ground connection. If electrical isolation is required, the system designer or integrator would be responsible for providing a s olution.

If your system does not support hot pl ugg in g (se e “ Hot Plug Support on page.25), it must be turned off and unplugged before installing your hard drive.

Physical Dimensions

Drive Mounting

You can mou nt the hard drive in the X, Y, or Z axis, depending upon the physi cal design of your system. For best results, mount the drive with all four screws grounded to the cha s s is. If all four screws are not used, see "Grounding" on page.12.

The hard drive should be mounted to the chassis using four 6-32 screws. Recommended screw torque is 5 in-lb. Maximum screw torque is 10 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. Western Ditigal’s minimum design criteria is to always meet the SFF 8301 industry standard specification. The industry standard as defined in the SFF 8301 specifies a maximum of 3 mm screw penetration, and for a minimum of 2.4 mm of thread engagement from both the screw and the hard drive.

See Figure 1

for allowable fastener penetration for this product family.

The PCBA and HDA grounds are always connected together in the drive and cannot be disconnected. The drive mounting screws, unless intentionally isolated, will provide additional ground connections between the HDA and the system chassis. If the drive isn't grounded via mounting screws as described Drive Installation” on Page.46, there may be increased electrical emissions (EMI).

Power Savings Modes

This product is capable of supporting both legacy ATA Advanced Power Management (APM) mode and the new more extensive Extended Power Conditions (EPC) standards. Unless otherwise specified, the default disk drive is shipped with the EPC mode enabled, and the legacy APM modes can be enabled via the Set Feature command (Feature ‘4A’h, Sub Command ‘04’h). These two power savings implementations are exclusively used, and thus not simultaneously supported.

This drive supports the legacy 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 spi n 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.

Hard Disk Drive

Technical Reference Manual

Ultrastar DC HA210

Western Digital drives additionally support T13 Extended Power Conditions, as stated in the ACS-2 specification. Power savings features, normally only available in notebook drives, are now included in our Enterprise products. With these features enabled, drive power can be reduced automatically via inactivity timer, or manually via Host command. In timer based mode, the drive automatically starts reducing its power based on inactivity of co mma nd s from the Host. With progression into the idle states, the drive saves more and more power, but consequently takes longer to recover and respond to Host media commands.

A summary of the new low power modes and what the drive does in each mode is shown below:

Idle_A

 Heads Floating Over Disk  <10 ms recovery

Idle_B

 Heads Parked  <650 ms recovery

Idle_C

 Heads Parked, Reduced RPM  3-15 sec recovery (see the Power Conditions Log for the drives actual recovery time)  Idle_c recovery current limited to the maximum user mode power.

Standby_Y

 Heads Parked, Reduced RPM  3-15 sec recovery (see the Power Conditions Log for the drives actual recovery time)  Standby_y recovery can use full spin up power.

Standby_Z

 Traditional standby  Drive not spinning  Recovery is similar to a typical TTR (Time To Ready) for the HDD

Western Digital has added the Power Condition Log, which defines the support, enable bits, and timers for all power conditions. The power management timers start running after a ll Host commanded drive activity is complete, and will run during drive background operations, but do not take effect until those background operations are completed. The timer expiration min/max values are visible to the Host/ Initiator, but are rounded silently by the drive to its internal min/max values. The timer enable and timer values can be marked independently as changeable. Please note that some Host Operating Systems may be unable to take advantage of the inactivity timers, as they constantly access the Drive with writes to update a time stamp. In these situatio ns it is advisable to extend the Idle_B ti mer value beyond the time interval of the writes, or to disab le the timer entirely. Please see your Western Digital representative for help with questions about these features .

SATA 6 Gb/s

SATA 6 Gb/s is the next generatio n interface for SATA hard drives. It adds to the functionality of the SATA 3 Gb/s interface with the following features:

 Native Command Queuing (NCQ) — server feature for performance in random I/O transaction

 Staggered Spin-up — allows the system to control whether the drive will spin up immediately or

 Asynchronous Signal Recove r y (ASR) — robustness feature that improves signal recovery.  Enclosure Services — defines external enclosure management and support features.  Backplane Interconnect — defines how to lay out signal line traces in a backplane.  Auto-activate DMA — provides increased command efficiency through automated activation of the

Time- Limited Error Recovery (TLER)

Western Digital has delivered coordinated error management in the form of Time Limited Error Recovery (TLER). TLER-capable hard drives will perform the normal error recovery and, after 7 seconds, issue an error message to the RAID controller and defer the error recovery task until a later time. With coordinated error handling, the hard drive is not dropped from the RAID array, thereby avoi ding the entire RAID recovery, replacement, rebuild, and return experience.

environments. It aggregates many small random data transfers and allows the disk to reorder the commands in a sequential order for faster access.

wait until the interface is fully ready before spinning up.

DMA controller.

The error handling is further coordina ted between the TLER-capable hard drive and the RAID card. The TLER capable drive will respond without waiting on the error to be resolved. RAID cards are very capable of handling this with a co mbination of parity protection and journaling. The RAID card flags the error in the error log and proceeds to deliver data using parity protection unt il the d rive retries its own error recovery and corrects the error. This is quite similar to error management proven in SCSI- RAID for many years. Though TLER is designed for RAID environments, it is fully compatible with and will not be detrimental when used in non-RAID environments.

Rotary Acceleration Feed Forward (RAFF)™

Rotary Acceleration Feed Forward (RAFF) helps to overcome the effects of rotational vibration (RV) on a hard drive by generating an additional control effort to counter the RV disturbances, thereby keeping the drive head(s) within the safe operating region during re ading and writing operations.

Figure 4 Dual Linear Sensor Rotational Acceleration Feed Forward (RAFF)

The RAFF implementation has three major components: RV sensing, RV con trol effort feed- forwarding and adaptation to environmental conditions.

 RV sensing in the RAFF implementation is accomplished by using two relatively inexpensive linear

accelerometers placed on the printed circuit board assembly (PCBA). The sensor locations are optimized for separation distance and PCB mounting conditions. Since the difference signal from two similar linear accelerometers placed in a parallel orientation and separated by some distance is indicative of RV, the signals are subtracted from each other to generate a Differential Sensor Signal (DSS).

 RV control effort feed-forwarding is achieved by digitizing the D SS, then, sending it to the

microprocessor of the drive. Using a control algorithm, the microprocessor generates a control effort signal based on the DSS. This feed forward control effort is in addition to the conventional servo control approach in hard drive operations.

 Adaptation to env ironmental conditions is crucial to the successful deployment of RAFF. This

design intelligently applies RAFF selectively and adapts to with individual drive parameters to maintain maximum performance in the hard drive.

Perpendicular Magnetic Recording (PMR)

In perpendicular magneti c recording (PMR), the magnetization of each data bit is aligned vertically to the spinning disk, rather than longitudinal ly as has been the case in hard drive technolo gy 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, enab ling 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 Western Digital engineers to reliably pack more data on a given disk than is possible with conve ntional longi tudinal recording.

IntelliSeek

This unique IntelliSeek technology proactively calculates an optimum seek speed to eliminate hasty movement of the actuator that produce s noise and requir es power, which is common in other drives. With IntelliSeek, the actuator’s mov ement is controlled so the head reaches the next target sector just in time to read the next piece of information, rather than rapidly accelerating and waiting for the drive rotation to catch up. This smooth motion reduces power usage by more than 60 percent compared with standard drives, as well as quiets seek operation and lowers vibration.

Native Command Queuing (NCQ)

These drives support Native Command Queuing. NCQ is a true Enterprise feature for environments such as database, Web servers, and e-mail servers.

Performance of a random I/O workload can be improved through intelligent re-orderi ng of the I/O requests so they read/write to and from the nearest available sectors and minimize the need for additional disk revol ut ions or head actuator movement. This improvement is achieved though Nat ive Command Queuing (NCQ).

NCQ allows the drive to re-order read commands, thereby increasing random read IOPs. Additional NCQ features that can prove beneficial include a Write Cache disabled IOP increase and a queuing implementation built upo n an existing, highly automated cache archit ecture. Queue d reads in NCQ leverage the same re-ordering schemes used for write caching. The firmware design maintains the "order" of overlapping/colliding queued commands. NCQ is designed to excel in multi-thread ed environments with high random I/O load s .

Pre- emptive Wear Leveling (PWL)

This feature provides a solution for protecting the recording media against mechanical wear. In cases where the dr ive is so busy with incoming commands that it is forced to stay in a same cylinder position for a long time, the PWL control engine initiates forced seeks so that disk lubricant maintains an even distribution and does not become depleted. This feature ensures reliab ility for applications that perform a high incidence of read/write operations at the same physical location on the disk.

MicroFemto Slider

These drives incorporate the next generation of femto slider form factor in which the read/write head is mounted on the small, lightweigh t microfemto slider that allows the head to move more quickly from track to track on the disk. Western Digital’s microfemto heads enhance tracking and increase shock

tolerance, producing a highly stable high-densi t y drive platf orm.

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. 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 capability is used to pass commands t hrough a driver interface or a br idge 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 pr ovides detailed information on the usage and c a pabilities of SCT. The SCT feature set includes the following commands:

 Write Same  Temperature Reporting

The Write Same command allows the host to erase the media, or write a pattern repeatedly across the media, with a minimum of data transfer from the host. The host can clear the entire media to zeros or a specific pattern by sending this command with the pattern as a parameter—no data transfer is necessary. Write Same can write the entire media, or just a portion of the media. The host can monitor the progress of the Write Same by issuing SCT Sta tus requests. This frees the host system to do other ta sks while the media is being cleared.

Write Same

Temperature Reporting

The SCT Temperature Reporting (SCT TR) feature allows a host system to access temperature information in the drive. The S.M.A.R.T. temperature value is reported within ±3°C of the base casting temperature. 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 susta i ned operating limits, warning level limits, and drive damage limits. In addition to r e porting the limits, SCT TR returns the current drive temperature (a temperature history which the host can use to predic t heating or cooling trends) and the maximum temperature achieved 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.

World Wide Name (WWN)

It has become a critical requirement that hard drives be uniquely identified by computer systems. This allows a drive to maintain its identity as it is transported from system to system or placed on a network. IEEE has defined a format for serial numbers that is widely recognized in the computing industry by adding World Wide Name (WWN) to ATA/ATAPI-7 in 2002.

The World Wide Name (WWN) defined in ATA/ATAPI-7 is a modification of the IEE E Extended Unique Identifier 64 bit standard (EUI -64) and is comprised of three major components: naming authority, organizationally unique identifier (OUI) and serial number. This product’s OUI is 0014EEh.

Power Loss Data Protection

Upon power loss, the drive utilizes stored spindle energy to back up the HDD cache to on- board flash. This allows deeper write queues which b oosts performance, while minimizing data loss / c orruption such as write splices that can occur during unexpected power losses.

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 s ystem or reboot. This capability contributes to both data availability and serviceability without any a ssoc ia te d downtime, making it a critical feature for extending SATA into enterprise applications.

The drive s upports hot plugging only in systems where a S ATA hard drive s torage backp lane is used. T he SATA 3.0 specification requires staggered pins for bo th 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 resis t ors to passive ly limit inrush current duri ng drive insertion.  Hot plug controllers to act ively limit inrush current during drive ins ertion.

Active LED Status

The drive supports 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 Spinup and Activity Indication (SATA Power Pin

Note: This feature is available for specific OEM configurations. SATA device power connector pin 11 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. Accord ing to the SATA spec, "Staggered Spin-up Disable and Activity Signal shall n ot be enabled at the same time."

Staggered Spinup

When multiple disks are installe d in an enclosure, it is desirable to provide a simple mechanism by which a subsystem controller can sequence hard drive initialization to minimize the curre nt load presented during power up. Staggered spinup provi des this mecha nism by preventing the hard d rives from spinni ng up until after successful PHY initializ a tion (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—a s a result of having been placed in Standby or Sleep power modes, for example—the drive shall s pin up following the rules that govern spinup from low power modes described in ATA/ ATAPI-6 o r later.

Activity Indication

11)

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.

Password Security Mode

The Security Mode feature set allows the user to create a device lock password that prevents unaut ho r iz ed hard drive access even if the drive is removed from the computer. This feature varies by drive configuration and may not be available on all configurations.

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 – FFFEh 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.

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.

Master and User Passwords

Security Levels

Data Path Protection (DPP)

DPP prevents possible electro nic failures from corrupting data on the hard drive. Although typically a very rare occurrence, there is the possibility of intermittent failures within the hard drive due to the electronics or connections on the printed circuit board inducing corruption of the data as it moves from the interface to the media. By incorporating DPP in our hard drives, Western Digital protects customer data with the ability to detect these type of rare events, and prevents incorrect data from being written to the media.

RELIABILITY

Reliability Considerations

The error rates stated in this spec ification assume the following: Operation of the drive at the minimum or maximum base casting temperature is intended for short time

periods only. You can enhance the reliability of the Western Digital hard drive by ensuring that the drive receives

adequate cooling. “Temperature Measurement” on page.17 P rovides temperature measurements and other information that may be used to enhance the service life of the drive. Recommended airflow information is provided in “Cooling” on page.18. The drive incorporates industry standard SelfMonitoring, Analysis and Reporting Te chnology (SMAR T).

If the system in which the drive is installed does not meet the characteristics defined in this TRM, please use a Western Digital drive that matches yo ur system's capability.

Error Rates

The error rates stated in this spec ification assume the following:

 The drive is operated per the DC power specified.  The drive has been formatted with the FORMAT UNIT command.  Errors previously detected as caused by media defects are excluded from further error rate

 Random error distribution

computations.

Error Rates

Error Rates are specified as based upon ECC On-The-Fly data correction, automatic retries being allowed, and all drive flaws reallocated.

Recoverable Read error rate: Less than 1 e rror in 10 Unrecoverable Read error rate: Less than 1 in 10 Mis-corrected Read error rate: Less than 1 se ctor in 10 Interface Error Rate: Less than 1 e rror in 10

A seek error is defined as a failure to position a head over the addressed track. As stated by the seek error rate above, if the drive detects a seek error it will automatically perform an error recovery procedure. If this error recovery fails, this is deemed an unrecoverable seek error and the drive will report back an ‘04’h sense key; these errors are classified as a drive failure as defined within our MTBF specification.

A typical read can return data at a rate as defined in our performance section without additional drive delay. This capability is based upon the LDPC (Low Density Parity Check) Channel technology which provides data with ECC On-The-Fly data correction capability.

Beyond thi s on-the-fly capability, read errors can occur and are defined as follows: Recoverable – whereby the drives error recovery procedure is required to correctly return the data after an

initial error condition was encountered.

Unrecoverable – whereby the drives error recovery procedures are unable to correctly return the data requested; this data should be allocated to a new area of the drive.

Mis-corrected – as specified in the error rate above the frequency for this type of occurrence is extremely rare. This type of event can occur as it relates to the tradeoffs of the channel technology engine against the quantity, lengths, and patterns of data errors which may occur

within a sector. As mentioned above the LDPC channel is required to enable the recoverable and unrecoverable error rates as specified above.

Before measuring read error rates, ensure that:

1. The data that is being used for measurement of read error rates must be verified that it is written

2. All media defect induced errors must be excluded from error rate calculations.

correctly on the media.

An interface error is defined as when the drive receiver detects errors of the incoming data whereby the drive in unable to recover the data as transmitted to the receiver. These errors can include any of: running disparity errors, illegal code, loss of word sync, or CRC errors.

Environmental Interference

When evaluating systems under condit ions of EMI, the p erformance of the drive within the system shall be considered acceptable if the drive does not generate an unrecoverable condition. This unrecoverable condition is defined as one that:

1. Is not detected and corrected by the drive itself.

2. Is not capable of being detected from the error or fault status provided through the drive or its

interface.

3. Is not capable of being recovered by normal drives or system recovery methods without operator

intervention.

Internal Environmental Protection System

This system protects the inside environ ment 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  Breather filter located at low pressure area  Enhanced heat dissipation

Defect Management

Every Western Digital drive undergoes factory-level intelligent burn in, which thorou ghl y te sts 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.

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.

Recoverable Errors

When a sector is recovered by firmware it is marked as needing repair. When a new host command writes to that sector, a sector test is performed by writing and reading to that location several times. If recovery is required to read the sector during the sector test, it is relocated.

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.

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 are specific to automatic defect retirement on writes (write auto-relocation):

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

 When host retries are enabled, the drive w ill internally flag any unrecoverable errors (DAMNF or ECC).

The drive has five means of error recovery:

 ECC On-the-Fly  Read/Write Retry Procedure  Extended Read Retry Procedure

ECC On-the-Fly – If an LDPC error occurs, the drive attempts to correct it on-the-fly without retries. Data can be corrected in this manner without performance penalty.

Read/Write Retry Procedure – This retry procedure is used by all disk controller error types. If the procedure succeeds in reading or writing the sector being tried, then recovery is complete and the controller continues with the command. Each retry operation also checks for servo errors. The procedure ends when error recovery is achieved or when all possible retries have been attempted.

Automatic Defect Retirement

reported.

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

Error Recovery Process

Extended Read Retry Procedure – This retry procedure tries combinations of positive/negative track offsets and data DAC manipulations to recover the data. This retry procedure applies only to read data recovery. The Read/Write Retry procedure performs the actual retry operation.

When an extended retry operation is successful, the controller continues with the command. The controller clears any changes in track offset or data DAC settings before the command continues.

SCT commands provide capabilities not covered in ATA/ATAPI-7 for commands that do not fit the ATA command delivery model. Some SCT commands report completion when the command begins e xecution. Execution progress for these commands may be checked by requesting SCT status. For instance, the host can track the progress of a Write Same command by issuing a status request once per minute. See ATA8ACS for a full description of SCT.

S.M.A.R.T. Capability. Bits are as follows:

S.M.A.R.T. (B0h)

The S.M.A.R.T. command provides access to attribute values, S.M.A.R.T. status, and other S.M.A.R.T. information. These commands can be used for logging and reporting purposes, and for accommodating special user needs.

Prior to writing the S.M.A.R.T. command to the Co mmand Register, the host must write key values into the LBA Mid and LBA High Registers (4Fh, C2h) or the command will be aborted and an error will be reported.

The S.M.A.R.T. command has several sub-commands that are selectable via the Features Register when t he host issues the S.M.A.R.T. command. To select a sub-command, the host must write the appropriate subcommand code to the Features Register before issuing the S.M.A.R.T. command. The sub-commands and their respective codes are listed below. For more detailed information on executing

S.M.A.R.T. commands, see the ATA-7 specification.

This command returns a sector of data with the drive's S.M.A.R.T. data structure.

DRIVE HANDLING AND MAINTENANCE

Hard drives are precision instruments that must be handled with care to prevent damage. It is important to understand that drives are typically damaged because of Electrostatic Discharge (ESD), rough handling, or shock and vibration.

Refer to https://www.wdc.com/support/hard-drive-support/warranty-returns for detailed instructions on all p hases of repackaging the drive.

Important: If your system does not support hot plugging (see “Hot Plug Support” on page

25), it must be turned off and unplugged before installing your hard drive.

Unpacking

Handling Precautions

Western Digital products are designed to withstand normal handling during unpacking and installation. Take care to avoid excessive mechanical shock 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.

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 Western Digital dri ve is not in its shipping container or installed in its pr oper host enclosure, it must remain in the antistati c bag. To pr event damage, do not unpack your Western Digital drive until you are ready to install it.

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 Western Digital representative if you observe any shipment damage. Always move the shipping container in the upright position indicated by the arrows on the container.

Removal From Shipping Container

Remove the Western Digital drive from the shipping container only for inspection or installation. Car efully open the bo x. When removing the Western Digital drive from the box, follow these precautions:

 Grasp the drive by the sides only; avoid touching the cir cuit board co mponents.  Gently place the drive on its antistatic bag on a clean, level, grounded work area.  Do not stack drives or stand the Western Ditigal drive on it s edge.

CAUTION: When removing the drive from the shipp i ng container, be careful not to drop it. Dropping the drive can severely damage the head disk assembly or printed circuit board.

GLOSSARY

Active LED Status — The drive supports externa l LED requirements. It provides an activity LED output which is ON during command execution and OFF otherwise.

Annualized Failure Rate (AFR) — A method of measuring failure rat es or tren ds 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 the 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 Transf er 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.

Data Path Protection (DPP) — A feature that prevents possible electronic failures by preventing corruption of data on the hard drive.

Dual Stage Actuator (DSA) — DSA is an imp rovement to the overall capability of the Servo system and provides a mechanical benefit to improve the response time (higher Bandwidth capability) of moving and maintaining the head position over the data tracks.

ECC On-the-Fly — Western Digital utilizes an LDPC hardware correction technique that corrects errors 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 utilizing LDPC technology 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 Western Digital performs on all its drive products to ensure compatibility with diffe rent 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. 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. IntelliSeek —The technology that proactively calculates an optimum seek speed to eliminate hasty movement of

the actuator that produces noise and requires power. Latency — The period of time that the read/write heads wait for the disk to rotate the data to an accessible position.

For a disk rotating at 10,000 RPM, the average latency is 3 milliseconds. Logical Block Address — An alternative addre s s ing methodology of identif ying a given lo cation on a SATA

drive that permits disk sizes greater than 528 MB.

MicroFemto Slider — Thes e drives incor porate the next generation femto slider form factor in which the read/ write head is mounted on the small, lightweight microfemto slider that allows the head to move more quickly from track to track on the disk.

Native Command Queuing (NCQ) — NCQ allows the drive to re-order read commands, thereby increasing random read IOPs. NCQ is a true Enterprise feature for environments such as database, Web servers, and e-mail servers.

Pre-emptive Wear Leveling (PWL) —The feature that provides a solution for protecting the recording media against mechanical wear.

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.

RoHS (Restriction o f Hazardous Substances) — Western Digital hard drive products manufactured and sold worldwide after June 8, 2011, meet or exceed Restriction of Hazardous Substances (RoHS) compliance requirements as mandated by the RoHS Directive 2011/65/EU. RoHS aims to protect human health and the environment by restricting the use of cer tain hazardous substances in new equipment, and consis ts of restrictions on lead, mercury, cadmium, and other substances.

Rotary Acceleration Feed Forward (RAFF) — These drives employ RAFF technology to maintain hard drive performance in high vibrat ion environments through adaptive compensation of the servo system.

Rotational Latency — The amount of delay in obtaining information from a disk drive that can be attributed to the rotation of the disk. For a disk ro ta ting at 10,000 RPM, the average latency is 3 milliseconds.

RPM (Revolutions per M inute) — Rotational speed of the media (disk), also known as the spindle speed. 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.

Sector — A 512-byte packet of data. Self-Monitoring, Analysis, and Reporting T echnology (S.M.A.R.T.) — A technology to assist the user in

preventing possible system down time due to hard drive failure. 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.

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.

Staggered Spinup — SATA feature that allows the system to control whether the drive will spin up immediately or wait until the interface is fully ready.

Thermal Asperity — A thermal asperity is a baseline shift in the read back signal due to heating of the mag ne to resistive stripe on the head as a result of physical contact with the disk or a particle.

Time-Limited Error Recovery (TLER) — TLER prevents hard drive error recovery fallout by limiting the time the drive spends in error recovery, providing increased performance, improved availability, and lower total cost of owners hip in RAI D arrays.

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

World Wide Name (WWN) — The World Wide Name (WWN) defined in ATA/ATAPI-7 is a modification of the

IEEE extended unique identifier 64 bit standard (EUI-64) and is comprised of three major components: namin g authority, organizationa lly unique identifier (OUI) and serial number..

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