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 the current system and expect all of the 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 to 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.

Note

• The host adapter may, optionally, emulate a master/slave environment to host software where two devices on separate Serial ATA ports are represented to host software as 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.

Recording and interface technology

Start/stop times

Power specifications

The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 4 on page 22.

Power consumption

Power requirements for the drives are listed in Table 2. 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 (8TB and 6TB)

*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

Typical current profiles

Figure 1. 8TB and 6TB Typical 5V startup and operation current profile

Figure 2. 8TB and 6TB Typical 12V startup and operation current profile

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.

Voltage tolerance

Voltage tolerance (including noise):

5V +10/ -5% 12V ± 10%

Extended Power Conditions – PowerChoiceTM

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 PowerChoice. 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. Fo r 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.

PowerChoice is invoked using one of two methods

• Automatic power transitions are triggered by the 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.

PowerChoice exits power-saving states under the following conditions

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

PowerChoice 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 product’s reliability and data integrity.

Environmental limits

Temperature and humidity values experienced by the drive must be such that condensation does not occur on any drive part. Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F (14.8°C).

Note: To maintain optimal performance drives should be run at nominal drive temperatures and humidity.

Temperature

• Operating
  • 41°F to 140°F (5°C to 60°C) drive case temperature range with a maximum temperature gradient of 36°F (20°C) per hour.
  • The maximum allowable drive case temperature is 140°F (60°C).
  • Airflow may be required to achieve consistent nominal case temperature values (see Section 3.4). To confirm that the required cooling is provided for the electronics and HDA, place the drive in its final mechanical configuration, and perform random write/read operations. After the temperatures stabilize, measure the case temperature of the drive. See Figure 3 for the HDA temperature checkpoint.
• Non-operating
  • – 40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This specification assumes that the drive is packaged in the shipping container designed by Seagate for use with the drive.

Humidity

The values below assume that no condensation on the drive occurs. Maximum wet bulb temperature is 84.2°F (29°C).

Relative humidity

Operating:| 5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.
---|---
Nonoperating:| 5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.

Effective Altitude (sea level)

• 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.

• 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.

Nonoperating shock

• 8TB and 6TB models
  The nonoperating shock level that the driver can experience without incurring physical damage or degradation in performance when subsequently put into operation is 250 Gs based on a nonrepetitive half-sine shock pulse of 2ms duration.

• 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.

• Operating vibration
  The maximum vibration levels that the drive may experience while meeting the performance standards specified in this document are specified below.

Nonoperating vibration

The maximum non-operating vibration levels that the drive may experience without incurring physical damage or degradation in performance when subsequently put into operation are specified below.

10–500 Hz Linear Random: 5.0 Grms ref

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)

*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.

Test for Prominent Discrete Tones (PDTs)

Seagate follows the ECMA-74 standards for the 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 before the computation of tone ratios according to Annex D of the ECMA-74 standards.

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 table:

Reliability

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
• Typical workload
• 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. 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..

Maximum Rated Workload

| Maximum rate of <550TB/year

Workloads exceeding the annualized rate may degrade the drive MTBF and impact product reliability. The Annualized Workload Rate is in units of TB per year, or TB per 8760 power on hours. Workload Rate = TB transferred * (8760 / recorded power-on hours).

Seagate designs its products to meet environmental protection requirements worldwide, including regulations restricting certain chemical substances.

European Union Restriction of Hazardous Substance Law

Restriction of Hazardous Substances in Electrical and Electronic Equipment

Seagate drives are designed to be compliant with the European Union RoHS “Recast” Directive 2011/65/EU (RoHS 2) as amended by Directive (EU) 2015/863. The RoHS2 restricts the use of certain hazardous substances such as Lead, Cadmium, Mercury, Hexavalent Chromium, Polybrominated Biphenyls (PBB) and Polybrominated Diphenyl Ether (PBDE), BisBis(2-Ethylhexyl) phthalate (DEHP), Benzyl butyl phthalate (BBP), Dibutyl phthalate (DBP), and Diisobutyl phthalate (DIBP) in electrical and electronic equipment (EEE).

Substances of Very High Concern (SVHC)

The European Union REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) Regulation (EC) 1907/2006 regulates chemicals shipped into and used in Europe. Several parts and materials in Seagate products are procured from external suppliers. We rely on the representations of our suppliers regarding the presence of REACH substances in these articles and materials. Our supplier contracts require compliance with our chemical substance restrictions, and our suppliers document their compliance with our requirements by providing full-disclosure material content declarations that disclose the inclusion of any REACH-regulated substance in such articles or materials. Product-specific REACH declarations are available upon request through your Seagate Sales Representative.

China Requirements —China RoHS 2

China RoHS 2 refers to the Ministry of Industry and Information Technology Order No. 32, effective July 1, 2016, titled Management Methods for the Restriction of the Use of Hazardous Substances in Electrical and Electronic Products. T o comply with China RoHS 2, Seagate determined this product’s Environmental Protection Use Period (EPUP) to be 20 years by the Marking for the Restricted Use of Hazardous Substances in Electronic and Electrical Products, SJT 11364-2014.

Taiwan Requirements — Taiwan RoHS

Taiwan RoHS refers to the Taiwan Bureau of Standards, Metrology and Inspection’s (BSMI) requirements in standard CNS 15663, Guidance to the reduction of the restricted chemical substances in electrical and electronic equipment. Seagate products must compl y 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.

Corrosive environment

Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years of 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 when 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 s 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) an d Mean Time Between Failure (MTBF) section.

Product Warranty

Beginning on the date of shipment to the customer and continuing for the period specified in the purchase contract, Seagat e 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 i n 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 the remaining warranty using the Seagate website (www.seagate.com). The drive serial number is required to determine the 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 damaged in transit. Contact the 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 the original unopened Seagate shipping package or 60 days unpackaged within the defined non-operating limits (refer to the environmental section in this manual). Storage can be extended to 1 year packaged o r unpackaged under optimal environmental conditions (25°C, <40% relative humidity non-condensing, and non-corrosive environment). During any storage period, the drive’s 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.

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, put on a grounded wrist strap, or ground oneself 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 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 ser-vice the drive. Other labels are used to seal out dirt and contamination.

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.

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 SAT A 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 direc t connection to be hot pluggable and blind mateable.

For installations that require cables, users can connect the drive as illustrated in Figure 4.

Each cable is keyed to ensure correct orientation. Seagate Exos 7E8 SATA drives support latching SATA connectors.

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 6 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 th e 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 sid e mounting holes.
• Do not overtighten the mounting screws (maximum torque: 6 in-lb).
• Do not cover the breather hole on the top cover.

Mechanical specifications

Refer to Figure 6 for detailed mounting configuration dimensions. See Section 3.4, “Drive mounting.”

6TB models

Note: These dimensions conform to the Small Form Factor Standard documented in SFF-8301 and SFF-8323, found at www.sffcommittee.org

About self-encrypting drives

• Self-encrypting drives (SEDs) offer encryption and security services for the protection of stored data, commonly known as “protection of data at rest.” These drives are compliant with the Trusted Computing Group (TCG) Enterprise Storage Specifications as detailed in Section 2.14.
• The Trusted Computing Group (TCG) is an 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 ATA commands:
  • Trusted Send
  • Trusted Receive

These commands are used to convey the TCG protocol to and from the drive in their command payloads.

• Data encryption
  • Encrypting drives use one inline encryption engine for each port, employing AES-256-bit data encryption keys with AES-XTS mode to encrypt all data before being written on the media and to decrypt all data as it is read from the media. The encryption engines are always in operation and cannot be disabled.
  • The 32-byte Data Encryption Key (DEK) is a random number that 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 it is in volatile temporary storage (DRAM) external to the encryption engine. A unique data encryption key is used for each of the drive’s possible 16 data bands (see Section 4.5).

Controlled 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 they also supply the correct credentials to prove the requester is authorized to perform the command.

• Admin SP
  The Admin SP allows the drive’s owner to enable or disable firmware download operations (see Section 4.4). Access to the Admin SP is available using the SID (Secure ID) password or the MSID (Manufacturers Secure ID) password.

• Locking 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 BandMasterX or EraseMaster passwords. Since the drive owner can define up to 16 data bands on the drive, each data band has its password called BandMasterX where X is the number of the data band (0 through 15).

• Default 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.

Random 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.

Drive locking

• In addition to changing the passwords, as described in Section 4.2.3, 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 for the band “LockOnReset” setting of “PowerCycle” to 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.
• When the drive is shipped from the factory, the firmware download port is unlocked.

Data 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 Band1 by specifying a start LBA and an LBA range. The real estate for this band is taken from the Global Band. An additional 14
• Data Bands may be defined in a similar way (Band2 through Band15) but before these bands can be allocated LBA space, they must first be individually enabled using the EraseMaster password.
• 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 and its own user-supplied password. The host may change the Encryption Key (see Section 4.6) or the password when required. The bands should be aligned to 4K LBA boundaries.

Cryptographic erase

• A significant 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 changes, the user data can never be recovered. This is tantamount to an instantaneous data erase and is very useful if the drive is to be scrapped or redispositioned.

Authenticated firmware download

In addition to providing a locking mechanism to prevent unwanted firmware download attempts, the drive also only accepts download files that have been cryptographically signed by the appropriate Seagate Design Center.
Three conditions must be met before the drive will allow the download operation:

• The download must be an SED file. A standard (base) drive (non-SED) file will be rejected.
• The download file must be signed and authenticated.
• As with a non-SED drive, the download file must pass the acceptance criteria for the drive. For example, it must apply to the correct drive model and have compatible revision and customer status.

Power 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 2.5 for power requirements on the standard (non-SED) drive models.

Supported commands

The SED models support the following two commands in addition to the commands supported by the standard (non-SED) models a s listed in Table 8:

• Trusted Send (5Eh) or Trusted Send DMA (5Fh)
• Trusted Receive (5Ch) or Trusted Receive DMA (5D)

RevertSP

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. To execute the RevertSP method the unique PSID (Physica l 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.

ATA Security Erase Unit Command on SED SATA drives

The ATA SECURITY ERASE UNIT command shall support both the Normal and Enhanced erase modes with the following modifications/additions:

• Normal Erase: Normal erase shall be accomplished by changing the media encryption key for the drive followed by an overwrite operation that repeatedly writes a single sector containing random data to the entire drive. The write operation shall bypass the media encryption. On reading back the overwritten sectors, the host will receive a decrypted version, using the new encryption key, of the random data sector (the returned data will not match what was written).
• Enhanced Erase: Enhanced erase shall be accomplished by changing the media encryption key for the drive.

Sanitize Device – CRYPTO SCRAMBLE EXT

• This command cryptographically erases all user data on the drive by destroying the current data encryption key and replacing it with a new data encryption key randomly generated by the drive. Sanitize Device is a command field B4h and Feature field 0011 h (CRYPTO SCRAMBLE EXT).
• The drive shall support the Sanitize Feature Set as defined in ANSI/INCITS ACS-2 with the exceptions and/or modifications described in this section.
• The drive shall not support the OVERWRITE EXT and BLOCK ERASE EXT sub-commands.
• Support of the SANITIZE FREEZE LOCK EXT command shall be determined on a customer-specific basis. OEM drives shall support the command.

About FIPS

The Federal Information Processing Standard (FIPS) Publication 140-2 is a U.S. Government Computer Security Standard used to accredit cryptographic modules. It is titled ‘Security Requirements for Cryptographic Modules (FIPS PUB 140-2)’ and is issued by the National Institute of Standards and Technology (NIST).

Purpose

This standard specifies the security requirements that will be satisfied by a cryptographic module utilized within a security system protecting sensitive but unclassified information. The standard provides four increasing, qualitative levels of security: Level 1, Level 2, Level 3, and Level 4. These levels are intended to cover the wide range of potential applications and environments in which cryptographic modules may be employed.

Seagate Enterprise SEDs

The SEDs referenced in this Product Manual have been validated by CMVP and have been thoroughly tested by a NVLAP accredited lab to satisfy FIPS 140-2 Level 2 requirements. To operate in FIPS Approved Mode of Operation, these SEDs require security initialization. For more information, refer to the ‘Security Rules’ section in the ‘Security Policy’ document uploaded on the NIST website. To reference the product certification visit – http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/1401vend.htm and search for “Seagate”.

Level 2 security

Security Level 2 enhances the physical security mechanisms of a Security Level 1 cryptographic module by adding the requirement for tamper-evidence, which includes the use of tamper-evident coatings or seals on removable covers of the module. Tamper-evident coatings or seals are placed on a cryptographic module so that the coating or seal must be broken to attain physical access to the critical security parameters (CSP) within the module. Tamper-evident seals are placed on covers to protect against unauthorized physical access. In addition, Security Level 2 requires, at a minimum, role-based authentication in which a cryptographic module authenticates the authorization of an operator to assume a specific role and perform a corresponding set of services

Figure 7. Example of FIPS tamper evidence labels.

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.

Hot-Plug compatibility

Seagate Exos 7E8 SATA drives incorporate connectors that enable users to hot plug these drives by 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) before changing the plane of operation. This time is required to ensure data integrity.

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 no t 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

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.

SeaTools 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 10 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.
