1.1 About the Serial ATA interface
The Serial ATA interface provides several advantages over the traditional (parallel) ATA interface. The primary advantages include:

• Easy installation and configuration with true plug-and-play connectivity. It is not necessary to set any jumpers or other configuration options.
• Thinner and more flexible cabling for improved enclosure airflow and ease of installation.
• Scalability to higher performance levels.

In addition, Serial ATA makes the transition from parallel ATA easy by providing legacy software support. Serial ATA was designed to allow users to install a Serial ATA  host adapter and Serial ATA disk drive in current systems and expect all existing applications to work as normal.
The Serial ATA interface connects each disk drive in a point-to-point configuration with the Serial ATA host adapter. There is no master/slave relationship with Serial  ATA devices like there is with parallel ATA. If two drives are attached on one Serial ATA host adapter, the host operating system views the two devices as if they were  both “masters” on two separate ports. This essentially means both drives behave as if they are Device 0 (master) devices.
The host adapter may, optionally, emulate a master/slave environment to host software where two devices on separate
Note
Serial ATA ports are represented to host software as a Device 0 (master) and Device 1 (slave) accessed at the same set of host bus addresses. A host adapter that emulates a  master/slave environment manages two sets of shadow registers. This is not a typical Serial ATA environment.
The Serial ATA host adapter and drive share the function of emulating parallel ATA device behavior to provide backward compatibility with existing host systems and  software. The Command and Control Block registers, PIO and DMA data transfers, resets, and interrupts are all emulated.
The Serial ATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the Shadow Register Block. All Serial ATA  devices behave like Device 0 devices. For additional information about how Serial ATA emulates parallel ATA, refer to the “Serial ATA: High Speed Serialized AT  Attachment” specification. The specification can be downloaded from www.serialata.org.

Drive specifications

Unless otherwise noted, all specifications are measured under ambient conditions, at 25°C, and nominal power. For convenience, the phrases the drive and this drive are used  throughout this manual to indicate the following drive models:.

2.1 Specification summary tables
The specifications listed in the following tables are for quick reference. For details on specification measurement or definition, see the appropriate section of this manual.

Table 1 Drive specifications summary

* All specifications above are based on native configurations.
** One GB equals one billion bytes and 1TB equals one trillion bytes when referring to hard drive capacity.
Accessible capacity may vary depending on operating environment and formatting.
*** During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to operational levels.
† Seagate does not recommend operating at sustained case temperatures above 60°C.
Operating at higher temperatures will reduce useful life of the product.

2.2 Formatted capacity

*One GB equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment and formatting.
2.2.1 LBA mode
When addressing these drives in LBA mode, all blocks (sectors) are consecutively numbered from 0 to n–1, where n is the number of guaranteed sectors as defined above.
See Section 4.3.1, “Identify Device command” (words 60-61 and 100-103) for additional information about 48-bit addressing support of drives with capacities over 137GB.

2.3 Recording and interface technology

2.4 Start/stop times

2.5 Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 3 on page 21.
2.5.1 Power consumption
Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on an average of drives tested, under nominal conditions, using  5.0V and 12.0V input voltage at 25°C ambient temperature.
Table 2 DC power requirements (2TB and 1TB) 

*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to operational levels.

2.5.1.1 Typical current profiles (2TB and 1TB models)

Figure 1. Typical 5V & 12V startup and operation current profile (2TB and 1TB models)

2.5.2 Conducted noise

Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12 V line or an
equivalent 15-ohm resistive load on the +5V line.

• Using 12V power, the drive is expected to operate with a maximum of 120mV peak-to-peak square-wave injected noise at up to
  10MHz.
• Using 5V power, the drive is expected to operate with a maximum of 100mV peak-to-peak square-wave injected noise at up to
  10MHz.

Note Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.

2.5.3 Voltage tolerance
Voltage tolerance (including noise):
5V ± 5%
12V ± 10%

2.5.4 Extended Power Conditions – Power Choice TM

Utilizing the load/unload architecture a programmable power management interface is provided to tailor systems for reduced  power consumption and performance  requirements.
The table below lists the supported power conditions available in Power Choice. Power conditions are ordered from highest power consumption (and shortest recovery time) to lowest power consumption (and longest recovery time) as follows: Idle_a power >= Idle_b power >= Idle_c power >= Standby_z power. The further users go down in  the table, the more power savings is actualized. For example, Idle_b results in greater power savings than the Idle_a power condition. Standby results in the greatest power savings.

Each power condition has a set of current, saved and default settings. Default settings are not modifiable. Default and saved settings persist across power-on resets. The current settings do not persist across power-on resets. At the time of manufacture, the default, saved and current settings are in the Power Conditions log match.

Power Choice is invoked using one of two methods

• Automatic power transitions which are triggered by expiration of individual power condition timers. These timer values may be customized and enabled using the Extended  Power Conditions (EPC) feature set using the standardized Set Features command interface.
• Immediate host commanded power transitions may be initiated using an EPC Set Features “Go to Power Condition” subcommand to enter any supported power condition. Legacy power commands Standby Immediate and Idle Immediate also provide a method to directly transition the drive into supported power conditions.

Power Choice exits power saving states under the following conditions

• Any command which requires the drive to enter the PM0: Active state (media access)
• Power on reset

Power Choice provides the following reporting methods for tracking purposes
Check Power Mode Command

• Reports the current power state of the drive

Identify Device Command

• EPC Feature set supported flag
• EPC Feature enabled flag is set if at least one Idle power condition timer is enabled

Power Condition Log reports the following for each power condition

• Nominal recovery time from the power condition to active
• If the power condition is Supported, Changeable, and Savable
• Default enabled state, and timer value
• Saved enabled state, and timer value
• Current enabled state, and timer value

S.M.A.R.T. Read Data Reports

• Attribute 192 – Emergency Retract Count
• Attribute 193 – Load/Unload Cycle Count

PowerChoice Manufacture Default Power Condition Timer Values
Default power condition timer values have been established to assure product reliability and data integrity. A minimum timer value threshold of two minutes ensures the  appropriate amount of background drive maintenance activities occur. Attempting to set a timer values less than the specified minimum timer value threshold will result in an  aborted EPC “Set Power Condition Timer” subcommand.

Setting power condition timer values less than the manufacturer specified defaults or issuing the EPC “Go to Power Condition” subcommand at a rate exceeding the default timers may limit this products reliability and data integrity.

2.7.1 Humidity
2.7.1.1 Relative humidity

2.7.1.2 Wet bulb temperature

2.7.2 Altitude

2.7.3 Shock
All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock may be applied in the X, Y or Z axis.
2.7.3.1 Operating shock
These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 70 Gs (read) and 40 Gs (write) based on half- sine shock pulses of 2ms. Shocks should not be repeated more than two times per second.
2.7.3.2 Nonoperating shock
The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 300 Gs based on a nonrepetitive half-sine shock pulse of 2ms duration.
2.7.4 Vibration
All vibration specifications assume that the drive is mounted securely with the input vibration applied at the drive mounting screws. Vibration may be applied in the X, Y or Z axis.
2.7.4.1 Operating vibration
The maximum vibration levels that the drive may experience while meeting the performance standards specified in this document are specified below.

* Rotary Random Operating Vibration
2.7.4.2 Nonoperating vibration
The maximum nonoperating vibration levels that the drive may experience without incurring physical damage or degradation in performance when subsequently put into operation are specified below.

2.8 Acoustics
Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All measurements are consistent with ISO document 7779. Sound power  measurements are taken under essentially free-field conditions over a reflecting plane. For all tests, the drive is oriented with the cover facing upward.
Note
For seek mode tests, the drive is placed in seek mode only. The number of seeks per second is defined by the following equation: (Number of seeks per second = 0.4 / (average latency + average access time).

Table 3 Fluid Dynamic Bearing (FDB) motor acoustics

*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to operational levels.

2.9 Test for Prominent Discrete Tones (PDTs)
Seagate follows the ECMA-74 standards for measurement and identification of PDTs. An exception to this process is the use of the absolute threshold of hearing. Seagate  uses this threshold curve (originated in ISO 389-7) to discern tone audibility and to compensate for the inaudible components of sound prior to computation of tone ratios  according to Annex D of the ECMA-74 standards.
2.10 Electromagnetic immunity
When properly installed in a representative host system, the drive operates without errors or degradation in performance when subjected to the radio frequency (RF)  environments defined in the following test methods per standard EN 55024:2010. See Table 4 below:

Table 4 Radio frequency environments

1 Field in Gauss at the drive envelope. Testing per procedures 20800109-349 and 20800109-350.
2 Passing Field in Gauss at the drive envelope. In practice, testing is conducted using a fixed distance from the bottom of the magnet to the top of the drive. Calibration of the field vs. distance is done with a Hall probe with no magnetic materials present.
3 Testing to be done with magnet 0.375” dia. x 0.100” Ni-plated DfES; B,~11.5 keg, magnetized along its length; the magnet is oriented with the length perpendicular to the drive cover/PCBA. Drive to be properly secured during test.

2.11 Reliability
2.11.1 Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)
The production disk drive shall achieve an annualized failure-rate of 0.44% (MTBF of 2,000,000 hours) over a 5 year service life when used in Enterprise Storage field conditions as limited by the following:

• 8760 power-on hours per year.
• HDA temperature as reported by the drive <= 40°C
• Ambient wet bulb temp <= 26°C
• The AFR (MTBF) is a population statistic not relevant to individual units
• ANSI/ISA S71.04-2013 G2 classification levels and dust contamination to ISO 14644-1 Class 8 standards (as measured at the device)
  The MTBF specification for the drive assumes the operating environment is designed to maintain nominal drive temperature and humidity. The rated MTBF is based  upon a sustained drive temperature of up to 122°F (40°C) and wet bulb temperature up to 78.8°F (26°C). Occasional excursions in operating conditions between the  rated MTBF conditions and the maximum drive operating conditions may occur without significant impact to the rated MTBF. However continual or sustained operation  beyond the rated MTBF conditions will degrade the drive MTBF and reduce product reliability.

2.15 Reference documents
Specification for Acoustic Test Requirement and Procedures Seagate part number: 30553-001
In case of conflict between this document and any referenced document, this document takes precedence.

2.16 Corrosive environment
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing cannot duplicate every potential application environment.
Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as electronic drive component reliability can be  affected by the installation environment. The silver, copper, nickel and gold films used in hard disk drives are especially sensitive to the presence of sulfide, chloride, and  nitrate contaminants. Sulfur is found to be the most damaging. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should  be minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives.
Seagate recommends that data centers be kept clean by monitoring and controlling the dust and gaseous contamination. Gaseous contamination should be within ANSI/ISA  S71.04-2013 G2 classification levels (as measured on copper and silver coupons), and dust contamination to ISO 14644-1 Class 8 standards, and MTBF rated conditions as  defined in the Annualized Failure Rate (AFR) and Mean Time Between Failure (MTBF) section.

2.17 Product warranty
Beginning on the date of shipment to the customer and continuing for the period specified in the purchase contract, Seagate warrants that each product (including  components and subassemblies) that fails to function properly under normal use due to defect in materials or workmanship or due to nonconformance to the applicable  specifications will be repaired or replaced, at Seagate’s option and at no charge to the customer, if returned by customer at customer’s expense to Seagate’s designated facility  in accordance with Seagate’s warranty procedure. Seagate will pay for transporting the repair or replacement item to the customer. For more detailed warranty information,  refer to the standard terms and conditions of purchase for Seagate products on the purchase documentation.
The remaining warranty for a particular drive can be determined by calling Seagate Customer Service at 1-800-468-3472. Users can also determine remaining warranty using  the Seagate web site (www.seagate.com). The drive serial number is required to determine remaining warranty information.

Shipping
When transporting or shipping a drive, use only a Seagate-approved container. Keep the original box. Seagate approved containers are easily identified by the Seagate  Approved Package label. Shipping a drive in a non-approved container voids the drive warranty. Seagate repair centers may refuse receipt of components improperly packaged  or obviously damaged in transit. Contact an authorized Seagate distributor to purchase additional boxes. Seagate recommends shipping by an air-ride carrier  experienced in handling computer equipment.
Storage
Maximum storage periods are 180 days within original unopened Seagate shipping package or 60 days unpackaged within the defined non-operating limits (refer to  environmental section in this manual). Storage can be extended to 1 year packaged or unpackaged under optimal environmental conditions (25°C, <40% relative humidity  non-condensing, and non-corrosive environment). During any storage period the drive non-operational temperature, humidity, wet bulb, atmospheric conditions, shock, vibration, magnetic and electrical field specifications should be followed.
Product repair and return information
Seagate customer service centers are the only facilities authorized to service Seagate drives. Seagate does not sanction any third-party repair facilities. Any unauthorized repair or tampering with the factory seal voids the warranty.

Configuring and mounting the drive

This section contains the specifications and instructions for configuring and mounting the drive.
3.1 Handling and static-discharge precautions
After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards. Observe the following standard handling and static-discharge precautions:

Caution

• Before handling the drive, users should put on a grounded wrist strap, or ground frequently by touching the metal chassis of a computer that is plugged into a grounded  outlet. Wear a grounded wrist strap throughout the entire installation procedure.
• Handle the drive by its edges or frame only.
• The drive is extremely fragile—handle it with care. Do not press down on the drive top cover.
• Always rest the drive on a padded, antistatic surface until mounted in the computer.
• Do not touch the connector pins or the printed circuit board.
• Do not remove the factory-installed labels from the drive or cover them with additional labels. Removal voids the warranty. Some factory-installed labels contain  information needed to service the drive. Other labels are used to seal out dirt and contamination.

3.2 Configuring the drive
Each drive on the Serial ATA interface connects point-to-point with the Serial ATA host adapter. There is no master/slave relationship because each drive is considered a  master in a point-to-point relationship. If two drives are attached on one Serial ATA host adapter, the host operating system views the two devices as if they were both  “masters” on two separate ports. Both drives behave as if they are Device 0 (master) devices.
3.3 Serial ATA cables and connectors
The Serial ATA interface cable consists of four conductors in two differential pairs, plus three ground connections. The cable size may be 30 to 26 AWG with a maximum  length of one meter (39.37 in). See Table 7 for connector pin definitions. Either end of the SATA signal cable can be attached to the drive or host.
For direct backplane connection, the drive connectors are inserted directly into the host receptacle. The drive and the host receptacle incorporate features that enable the  direct connection to be hot pluggable and blind makeable.
For installations which require cables, users can connect the drive as illustrated in Figure 3.
Each cable is keyed to ensure correct orientation. Exons 7E2 drives support latching SATA connectors.

3.4 Drive mounting
Users can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the bottom-mounting holes. See Figure 4 for drive mounting dimensions. Follow these important mounting precautions when mounting the drive:

• Allow a minimum clearance of 0.030 in (0.76mm) around the entire perimeter of the drive for cooling.
• Use only 6-32 UNC mounting screws.
• The screws should be inserted no more than 0.140 in (3.56mm) into the bottom or side mounting holes.
• Do not overtighten the mounting screws (maximum torque: 6 in-lb).

3.4.1 Mechanical specifications
Refer to Figure 4 for detailed mounting configuration dimensions. See Section 3.4, “Drive mounting.”

Note
These dimensions conform to the Small Form Factor Standard documented in SFF-8301 and SFF-8323, found at www.sffcommittee.org
Note
The images below are for mechanical tolerance reference only and may not be a visual representation of the actual drive.

Serial ATA (SATA) interface

These drives use the industry-standard Serial ATA interface that supports FIS data transfers. It supports ATA programmed input/output (PIO) modes 0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–6.
For detailed information about the Serial ATA interface, refer to the “Serial ATA: High Speed Serialized AT Attachment” specification.
4.1 Hot-Plug compatibility
Exons 7E2 drives incorporate connectors which enable users to hot plug these drives in accordance with the Serial ATA Revision 3.2 specification. This specification can be downloaded from www.serialata.org.

Caution
The drive motor must come to a complete stop (Ready to spindle stop time indicated in Section 2.4) prior to changing the plane of operation. This time is required to insure data integrity.

4.2 Serial ATA device plug connector pin definitions
Table 7 summarizes the signals on the Serial ATA interface and power connectors.

Notes:

1. All pins are in a single row, with a 1.27mm (0.050”) pitch.
2. The comments on the mating sequence apply to the case of backplane blind ate connector only. In this case, the mating sequences are:
   • the ground pins P4 and P12.
   • the pre-charge power pins and the other ground pins.
   • the signal pins and the rest of the power pins.
3. There are three power pins for each voltage. One pin from each voltage is used for pre-charge when installed in a blind-mate backplane configuration.
4. All used voltage pins (Vex) must be terminated.

4.3 Supported ATA commands
The following table lists Serial ATA standard commands that the drive supports. For a detailed description of the ATA commands, refer to the Serial ATA: High Speed  Serialized AT Attachment specification. See “S.M.A.R.T. commands” on page 31.for details and subcommands used in the S.M.A.R.T. implementation.
Table 8 Supported ATA commands

4.3.1 Identify Device command
The Identify Device command (command code ECH) transfers information about the drive to the host following power up. The data is organized as a single 512-byte block  of data, whose contents are shown in Table 8 on page 24. All reserved bits or words should be set to zero. Parameters listed with an “x” are drive-specific or vary with the  state of the drive. See Section 2.0 on page 6 for default parameter settings.
The following commands contain drive-specific features that may not be included in the Serial ATA specification.
Table 9 Identify Device commands

Note See the bit descriptions below for words 63, 84, and 88 of the Identify Drive data.
Table 10 Bit descriptions for Words 63, 84 & 88

4.3.2 Set Features command
This command controls the implementation of various features that the drive supports. When the drive receives this command, it sets BSY, checks the contents of the  Features register, clears BSY and generates an interrupt. If the value in the register does not represent a feature that the drive supports, the command is aborted. Power-on  default has the read look-ahead and write caching features enabled. The acceptable values for the Features register are defined as follows

02H           Enable write cache (default).
03H           Set transfer mode (based on value in Sector Count register).
Sector Count register values:
00H  Set PIO mode to default (PIO mode 2).
01H Set PIO mode to default and disable IORDY (PIO mode 2). 08H PIO mode 0
09H PIO mode 1 0AH PIO mode 2 0BH  PIO mode 3
0CH  PIO mode 4 (default) 20H Multiword DMA mode 0 21H Multiword DMA mode 1 22H Multiword DMA mode 2 40H Ultra DMA mode 0
41H Ultra DMA mode 1 42H Ultra DMA mode 2 43H Ultra DMA mode 3 44H Ultra DMA mode 4 45H Ultra DMA mode 5 46H  Ultra DMA mode 6
10H           Enable use of SATA features
55H           Disable read look-ahead (read cache) feature. 82H        Disable write cache
90H           Disable use of SATA features
AAH          Enable read look-ahead (read cache) feature (default).
F1H           Report full capacity available
Note At power-on, or after a hardware or software reset, the default values of the features are as indicated above.

4.3.3 S.M.A.R.T. commands
S.M.A.R.T. provides near-term failure prediction for disk drives. When S.M.A.R.T. is enabled, the drive monitors predetermined drive attributes that are susceptible to  degradation over time. If self-monitoring determines that a failure is likely, S.M.A.R.T. makes a status report available to the host. Not all failures are predictable. S.M.A.R.T.  predictability is limited to the attributes the drive can monitor.
For more information on S.M.A.R.T. commands and implementation, see the Draft ATA-5 Standard.
Sea Tools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4H) that eliminates unnecessary drive returns. The diagnostic software ships  with all new drives and is also available at: http://www.seagate.com/support/downloads/seatools/.
This drive is shipped with S.M.A.R.T. features disabled. Users must have a recent BIOS or software package that supports S.M.A.R.T. to enable this feature. The table below shows the S.M.A.R.T. command codes that the drive uses.

Table 12 S.M.A.R.T. commands

Note
If an appropriate code is not written to the Features Register, the command is aborted and 0x 04 (abort) is written to the Error register.
