www.seagate.com Introduction

1.1 About the SATA interface

The Serial ATA (SATA) 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, SATA makes the transition from parallel ATA easy by providing legacy software support. SATA was designed to
allow users to install a SATA host adapter and SATA disk drive in the current system and expect all of the existing
applications to work as normal.
The SATA interface connects each disk drive in a point-to-point configuration with the SATA host adapter. There is no
master/slave relationship with SATA devices like there is with parallel ATA. 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. This
essentially means both drives behave as if they are Device 0 (master) devices.
The SATA 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 SATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as
the Shadow Register Block. All SATA devices behave like Device 0 devices. For additional information about how SATA
emulates parallel ATA, refer to the “Serial ATA International Organization: Serial ATA Revision 3.2”. The specification can be
downloaded from www.sata-io.org.

The host adapter may, optionally, emulate a master/slave environment to host software where two
devices on separate SATA ports are represented to host software as a Device 0 (master) and Device 1
Note (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 SATA environment.

Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive
diagnostics. The specifications in the table below are defined as follows:
• Track-to-track seek time is an average of all possible single-track seeks in both directions.
• Average seek time is a true statistical random average of at least 5000 measurements of seeks between random tracks,
less overhead.

Typical seek times (ms) Read Write

Track-to-track 1.0 1.2

Average 8.5 9.5

Average latency 4.16

These drives are designed to consistently meet the seek times represented in this manual. Physical seeks,
regardless of mode (such as track-to-track and average), are expected to meet the noted values. However,
Note due to the manner in which these drives are formatted, benchmark tests that include command overhead
or measure logical seeks may produce results that vary from these specifications.

2.8 Power specifications

The drive receives DC power (+5V or +12V) through a native SATA power connector. Refer to Figure 1 on page 21.

2.8.1 Power consumption

Power requirements for the drives are listed in Table 2 and Table 3. 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 elec-
tronics are in power-down mode.

2.8.2 Conducted 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 of 100 mV 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.

2.8.3 Voltage tolerance

Voltage tolerance (including noise):
• 5V ±5%
• 12V +10% / -7.5%

2.8.4 Power-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:

Power modes Heads Spindle Buffer

Active Tracking Rotating Enabled

Idle Tracking Rotating Enabled

Standby Parked Stopped Enabled

Sleep Parked Stopped Disabled

• 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, the drive 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 dis-
abled, 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 trans-
lation 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 com-
mands and returns to Active mode when disk access is necessary.

2.15 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 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.

3.0 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, 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 service the drive. Other labels are used to seal out dirt and
contamination.

3.2 Configuring 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.

3.3 SATA 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 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 mateable.
For installations which require cables, users can connect the drive as illustrated in Figure 1.

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. Refer to Figure 2 and Figure 3 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 0.120 inch (3.05mm) into the bottom or side mounting holes.
• Do not overtighten the mounting screws (maximum torque: 6 inch-lb).

www.seagate.com About (SED) Self-Encrypting Drives

4.0 About (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.trustedcomputinggroup.org)
• TCG Storage Security Subsystem Class Opal Specification, Version 2.0 (see www.trustedcomputinggroup.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.

4.1 Data 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 (TBD)).

4.2 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 the user provides the correct credentials to prove that they are
authorized to perform the command.

4.2.1 Admin 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.

4.2.2 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 Admin or User passwords.

4.2.3 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.

4.2.4 ATA 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.

4.3 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.

Seagate BarraCuda Product Manual, Rev. D 26

www.seagate.com About (SED) Self-Encrypting Drives

4.4 Drive 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.

4.5 Data Bands (TBD)

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.

4.6 Cryptographic 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.

4.7 Authenticated 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.

4.8 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 2.8 Power specifications for power requirements on the standard (non-SED) drive models.

4.9 Supported 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 8:
• Trusted Send
• Trusted Receive

4.10 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. 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.

5.3.2 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:
Table 10 Set Features command
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.

5.3.3 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.
SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4 H ) that eliminates
unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:
http://seatools.seagate.com.
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 11 S.M.A.R.T. commands
Code in features register S.M.A.R.T. command
D0H S.M.A.R.T. Read Data

D2H S.M.A.R.T. Enable/Disable Attribute Autosave

D3H S.M.A.R.T. Save Attribute Values

D4H S.M.A.R.T. Execute Off-line Immediate (runs DST)

D5H S.M.A.R.T. Read Log Sector

D6H S.M.A.R.T. Write Log Sector

D8H S.M.A.R.T. Enable Operations

D9H S.M.A.R.T. Disable Operations

DAH S.M.A.R.T. Return Status

If an appropriate code is not written to the Features Register, the

Note command is aborted and 0x 04 (abort) is written to the Error register.
