Seagate SkyHawk Product Manual, Rev. B 7
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 3.0”. The specification can be
downloaded from www.sata-io.org.
Note
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
(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.

2.7.4 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:
•Activemode
The drive is in Active mode during the read/write and seek operations.
• Idle mode
The electronics remain powered, and the drive accepts all commands and returns to Active mode when disk access
is necessary.
•Standbymode
The drive enters Standby mode immediately when the host sends a Standby Immediate command. If the host has
set the standby timer, the drive enters Standby mode automatically after the drive has been inactive for a specifi-
able length of time. The standby timer delay is established using a Standby or Idle command. In Standby mode, the
electronics are in low power mode, the heads are parked and the spindle is at rest. The drive accepts all commands
and returns to Active mode when disk access is necessary.
• Sleep mode
The drive enters Sleep mode after receiving a Sleep command from the host. In Sleep mode, the electronics are in
low power mode, 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.
• 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.

2.9 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.
*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.
2.9.1 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 Table 5.
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

2.11 Warranty
To determine the warranty for a specific drive, use a web browser to access the following web page:
www.seagate.com/support/warranty-and-replacements/
From this page, click on “Is my Drive under Warranty”. Users will be asked to provide the drive serial number, model
number (or part number) and country of purchase. The system will display the warranty information for the drive.
2.11.1 Data loss under power interruption with write cache enabled
Drive preserves its data during all operations except in cases where power to the drive is interrupted during write
operations. This could result in either an uncorrected data error being reported, or the entire sector/track becoming
unreadable. This can be permanently recovered by rewriting to the same location on the drive. Additionally any data
present in the DRAM buffer will not be written to the disk media, additionally, the drive will not be able to return the
original data.
In order to prevent this data loss, the host should issue a standby immediate or flush cache command before a controlled
power off operation to the drive.
2.11.2 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.
2.12 HDD and SSD Regulatory Compliance and Safety
For the latest regulatory and compliance information see: www.seagate.com/support/ scroll down the page and click the
Compliance, Safety and Disposal Guide link.
2.12.1 Safety certification
The following regulatory model numbers represent all features and configurations within the series:
SKR002: 1/2D (4TB & 2TB Models)
SKR004: 3/4D (6TB Models)
2.13 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 users mount 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 6 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.
Figure 1 Attaching SATA cabling
Each cable is keyed to ensure correct orientation. SkyHawk 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. Refer to Figure 2 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: 8 inch-lb).
