When referring to drive capacity, one gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one trillion bytes. Your computer’s operating system may use a different
standard of measurement and report a lower capacity. In addition, some of the listed capacity is used for formatting and other functions, and thus will not be available for data storage.
Actual quantities will vary based on various factors, including file size, file format, features and application software. Actual data rates may vary depending on operating environment and
other factors. The export or re-export of hardware or software containing encryption may be regulated by the U.S. Department of Commerce, Bureau of Industry and Security (for more

2.7Start/stop times
Time-to-ready may be longer than normal if the drive power is removed without going through normal OS powerdown
procedures.
2.8Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. Refer to Figure 2 on page 25.
2.8.1Power consumption
Power requirements for the drives are listed in Table 3, Table 4, Table 5 and Table 6. 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.
•Spinup power
Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.
•Read/write power and current
Read/write power is measured with the heads on track, based on a 16-sector write followed by a 32-ms delay, then a 16-sector
read followed by a 32-ms delay.
•Operating power and current
Operating power is measured using 40 percent random seeks, 40 percent read/write mode (1 write for each 10 reads) and 20
percent drive idle mode.
•Idle mode power
Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in a random track
location.
•Standby mode
During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/write electronics are
in power-down mode.

2.8.2Conducted noise
Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12 volt line or
an equivalent 15-ohm resistive load on the +5 volt line.
•Using 12-volt power, the drive is expected to operate with a maximum of 120 mV peak-to-peak square-wave injected noise at up
to 10MHz.
•Using 5-volt power, the drive is expected to operate with a maximum of100 mV peak-to-peak square-wave injected noise at up
to 10MHz.
2.8.3Voltage tolerance
Voltage tolerance (including noise):
•5V ±5%
•12V +10% / -7.5%
2.8.4Power-management modes
The drive provides programmable power management to provide greater energy efficiency. In most systems, users can control
power management through the system setup program. The drive features the following power-management modes:
•Active mode
The drive is in Active mode during the read/write and seek operations.
•Idle mode
The buffer remains enabled, and the drive accepts all commands and returns to Active mode any time disk access is necessary.
•Standby mode
The drive enters Standby mode when the host sends a Standby Immediate command. If the host has set the standby timer, the
drive can also enter Standby mode automatically after the drive has been inactive for a specifiable length of time. The standby
timer delay is established using a Standby or Idle command. In Standby mode, thedrive buffer is enabled, the heads are parked
and the spindle is at rest. The drive accepts all commands and returns to Active mode any time disk access is necessary.
•Sleep mode
The drive enters Sleep mode after receiving a Sleep command from the host.In Sleep mode, the drive buffer is disabled, the
heads are parked and the spindle is at rest. The drive leaves Sleep mode after it receives a Hard Reset or Soft Reset from the host.
After receiving a reset, the drive exits Sleep mode and enters Standby mode with all current translation parameters intact.
•Idle and Standby timers
Each time the drive performs an Active function (read, write or seek), the standby timer is reinitialized and begins counting
down from its specified delay times to zero. If the standby timer reaches zero before any drive activity is required, the drive
makes a transition to Standby mode. In both Idle and Standby mode, the drive accepts all commands and returns to Active
mode when disk access is necessary.
Note
Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.

2.10Acoustics
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.
*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.
2.10.1Test 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.
2.11Electromagnetic 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
Table 8.
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

2.14.3Taiwan Requirements — Taiwan RoHS
Taiwan RoHS refers to the Taiwan Bureau of Standards, Metrology and Inspection’s (BSMI) requirements in standard CNS 15663,
Guidance to reduction of the restricted chemical substances in electrical and electronic equipment. Seagate products must comply
with the “Marking of presence” requirements in Section 5 of CNS 15663, effective January 1, 2018. This product is Taiwan RoHS
compliant.
The following table meets the Section 5 “Marking of presence” requirements.
2.15Corrosive 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 Seagate products are especially sensitive to the presence
of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic components should
never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient
relative humidity greater than 95%. 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.

•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 mounting it 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.
3.2Configuring the drive
Each drive on the SATA interface connects point-to-point with the SATA 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 SATA 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.
SATA drives are designed for easy installation. It is usually not necessary to set any jumpers on the drive for proper operation;
however, if users connect the drive and receive a “drive not detected” error, the SATA-equipped motherboard or host adapter may
use a chipset that does not support SATA speed autonegotiation.
3.3SATA cables and connectors
The SATA 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 inches). See
Table 11 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 mateable.
For installations which require cables, users can connect the drive as illustrated in
Figure 2.

3.4Drive 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. Refer to
Figure 3 through Figure 5 for drive mounting dimensions. Follow these important mounting precautions when
mounting the drive:
•Allow a minimum clearance of 0.030 inches (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 inch (3.56mm) into the bottom or side mounting holes.
•Do not overtighten the mounting screws (maximum torque: 6 inch-lb).

www.seagate.comAbout (SED) Self-Encrypting Drives
4.0About (SED) Self-Encrypting Drives
Self-encrypting drives (SEDs) offer encryption and security services for the protection of stored data, commonly known as "data at
rest". These drives are compliant with the Trusted Computing Group (TCG) Opal Storage Specifications as detailed in the following:
•TCG Storage Architecture Core Specification, Version 2.0 (see www.trustedcomputin
ggroup.org)
•TCG Storage Security Subsystem Class Opal Specification, Version 2.0 (see www.trustedcomputin
ggroup.org)
In case of conflict between this document and any referenced document, this document takes precedence.
The Trusted Computing Group (TCG) is a standards organization sponsored and operated by companies in the computer, storage
and digital communications industry. Seagate's SED models comply with the standards published by the TCG.
To use the security features in the drive, the host must be capable of constructing and issuing the following two SATA commands:
•Trusted Send
•Trusted Receive
These commands are used to convey the TCG protocol to and from the drive in their command payloads. Seagate Secure SEDs also support TCG
Single User Mode, which can be disabled.
4.1Data Encryption
Encrypting drives use one inline encryption engine within each drive employing AES-256 algorithms in Cipher Block Chaining (CBC) mode to
encrypt all data prior to being written on the media and to decrypt all data as it is read from the media. The encryption engine is always in
operation and cannot be disabled. The 32-byte Data Encryption Key (DEK) is a random number which is generated by the drive, never leaves the
drive, and is inaccessible to the host system. The DEK is itself encrypted when it is stored on the media and when in volatile temporary storage
(DRAM), which is external to the encryption engine. A unique data encryption key is used for each of the drive's possible16 data bands (see
Section 4.5 Data Bands).
4.2Controlled Access
The drive has two security providers (SPs) called the "Admin SP" and the "Locking SP." These act as gatekeepers to the drive security services.
Security-related commands will not be accepted unless the user provides the correct credentials to prove that they are authorized to perform the
command.
4.2.1Admin SP
The Admin SP allows the drive's owner to enable or disable firmware download operations (see Section 4.4 Drive Locking). Access to the
Admin SP is available using the SID (Secure ID) password.
4.2.2Locking SP
The Locking SP controls read/write access to the media and the cryptographic erase feature. Access to the Locking SP is available using the Admin
or User passwords.
4.2.3Default password
When the drive is shipped from the factory, all passwords are set to the value of MSID. This 32-byte random value can only be read by the host
electronically over the interface. After receipt of the drive, it is the responsibility of the owner to use the default MSID password as the authority to
change all other passwords to unique owner-specified values.
4.2.4ATA Enhanced Security
The drive can utilize the system's BIOS through the ATA Security API for cases that do not require password management and additional security
policies.
Furthermore, the drive's ATA Security Erase Unit command shall support both Normal and Enhanced Erase modes with the following
modifications/additions:
Normal Erase: Normal erase feature shall be performed by changing the Data Encryption Key (DEK) of the drive, followed by an overwrite
operation that repeatedly writes a single sector containing random data to the entire drive. This write operation bypasses the media encryption.
On reading back the overwritten sectors, the host will receive a decrypted version, using the new DEK of the random data sector (the returned
data will not match what was written).
Enhanced Erase: Enhanced erase shall be performed by changing the Data Encryption Key of the drive.
4.3Random Number Generator (RNG)
The drive has a 32-byte hardware RNG that it is uses to derive encryption keys or, if requested to do so, to provide random numbers to the host for
system use, including using these numbers as Authentication Keys (passwords) for the drive's Admin and Locking SPs.
Seagate Desktop HDD Product Manual, Rev. Y30
www.seagate.comAbout (SED) Self-Encrypting Drives
4.4Drive Locking
In addition to changing the passwords, as described in Section 4.2.3 Default password, the owner should also set the data access controls for
the individual bands.
The variable "LockOnReset" should be set to "PowerCycle" to ensure that the data bands will be locked if power is lost. In addition
"ReadLockEnabled" and "WriteLockEnabled" must be set to true in the locking table in order for the bands "LockOnReset" setting of "PowerCycle"
to actually lock access to the band when a "PowerCycle" event occurs. This scenario occurs if the drive is removed from its cabinet. The drive will
not honor any data read or write requests until the bands have been unlocked. This prevents the user data from being accessed without the
appropriate credentials when the drive has been removed from its cabinet and installed in another system.
4.5Data Bands
When shipped from the factory, the drive is configured with a single data band called Band 0 (also known as the Global Data Band) which
comprises LBA 0 through LBA max. The host may allocate additional bands (Band1 to Band15) by specifying a start LBA and an LBA range. The real
estate for this band is taken from the Global Band.
Data bands cannot overlap but they can be sequential with one band ending at LBA (x) and the next beginning at LBA (x+1).
Each data band has its own drive-generated encryption key. The host may change the Encryption Key (see
Section 4.6 Cryptographic Erase)
or the password when required.
4.6Cryptographic Erase
A valuable feature of SEDs is the ability to perform a cryptographic erase. This involves the host telling the drive to change the data encryption key
for a particular band. Once changed, the data is no longer recoverable since it was written with one key and will be read using a different key.
Since the drive overwrites the old key with the new one, and keeps no history of key the older key, the user data can never be recovered. This is
done in a matter of seconds and is very useful if the drive is to be scrapped or repurposed.
4.7Authenticated Firmware Download
In addition to providing a locking mechanism to prevent unwanted firmware download attempts, the drive also only accepts download files
which have been cryptographically signed by the appropriate Seagate Design Center.
Three conditions must be met before the drive will allow the download operation:
1. The download must be an SED file. A standard drive (non-SED) file will be rejected.
2. The download file must be signed and authenticated.
3. As with a non-SED drive, the download file must pass the acceptance criteria for the drive. For example it must be applicable to the correct drive
model, and have compatible revision and customer status.
4.8Power Requirements
The standard drive models and the SED drive models have identical hardware, however the security and encryption portion of the drive controller
ASIC is enabled and functional in the SED models. This represents a small additional drain on the 5V supply of about
30mA and a commensurate increase of about 150mW in power consumption. There is no additional drain on the 12V supply. See the tables in
Section 2.8 Power specifications for power requirements on the standard (non-SED) drive models.
4.9Supported Commands
The SED models support the following two commands in addition to the commands supported by the standard (non-SED) models as listed in
Table 12:
•Trusted Send
•Trusted Receive
4.10RevertSP
SED models will support the RevertSP feature which erases all data in all bands on the device and returns the contents of all SPs (Security
Providers) on the device to their original factory state. In order to execute the RevertSP method the unique PSID (Physical Secure ID) printed on
the drive label must be provided. PSID is not electronically accessible and can only be manually read from the drive label or scanned in via the 2D
barcode.
Seagate Desktop HDD Product Manual, Rev. Y31

5.0SATA Interface
These drives use the industry-standard Serial ATA (SATA) interface that supports FIS data transfers. It supports ATA programmed
input/output (PIO) modes 0 to 4; multiword DMA modes 0 to 2, and Ultra DMA modes 0 to 6.
For detailed information about the SATA interface, refer to the “Serial ATA: High Speed Serialized AT Attachment” specification.
5.1Hot-Plug compatibility
Desktop HDD drives incorporate connectors which enable users to hot plug these drives in accordance with the SATA Revision 3.2
specification. This specification can be downloaded from
www.serialata.org.
5.2SATA device plug connector pin definitions
Table 11 summarizes the signals on the SATA interface and power connectors.
Notes
1.All pins are in a single row, with a 1.27 mm (0.050 in) pitch.
2.The comments on the mating sequence apply to the case of backplane blindmate 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.
• All used voltage pins (V

5.3.2Set 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:
