1.1About the Serial ATA (SATA) 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 transiti o n from pa rallel ATA easy by providi ng legacy sof twar e suppo rt. S erial
ATA was designed to allow you to install a Serial ATA host adapter and Serial ATA disc drive in your current
system and expect all of your existing applications to work as normal.
The Serial ATA interface connects each disc 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.
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 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 cont ai ns a set of registe rs that sha dow the conte nts of the traditional device r egisters, 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 http://www.serialata.com.

2.9Power specifications
The drive receives DC power (+5V) through a native SATA power connector.
2.9.1Power consumption
Power requirements for the drives are listed in Table 3, on page 8. Typical power measurements are based on
an average of drives tested, under nominal conditions, at 25°C ambient temperature.
• Spinup power
Spinup power is measured from the time of power-on to the time that the drive spindle re aches operating speed.
• Seek mode
During seek mod e, the read /write actuator arm move s toward a spe cific positi on on the d isc surface and does
not execute a read or write operati on. Servo ele ctronics ar e acti ve. Seek mode power is mea sure d based on
three random seek operations every 100 msecs. This mode is not typical.
• Read/write power and current
Read/write power is measured with the heads on track, based on three 63 sector read or write operations
every 100 msecs.
• 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 model

2.9.1.1Typical current profiles
Figure 1. Typical 5V startup and operating current profile
2.9.2Deferred spinup
Momentus 7200.1 SATA drives provid e a def erred spinup feature which storage subsystem controllers ca n use
to sequence disc drive initialization. This is beneficial to systems which include multiple Serial ATA hard disc
drives because it allows subsystem controllers to stagger the spinup of each drive to accommodate available
power supply current. This feature does not impact time-to-ready in typical desktop systems.
To accommodate the deferred spinup of multiple disc drives in an enclosure, Momentus 7200.1 SATA disc
drives will spin up only after power is applied to the drive and after successful PHY (Physical layer) initialization. PHY initialization occurs aft er the PHY enters the DP7: DR_Ready state. This state is reached after a successful exchange of Out-Of-Band (OOB) signals with a functional host-side Serial ATA port. In desktop
systems, SATA transceivers should initialize OOB as soon as power comes ready to guarantee the drive spins
up quickly. Seagate disc drives will not spin up without an operational host-side Serial ATA transceiver.
Additional details
Upon system power up, PHY communication is initiated with a COMRESET signal, which is generated by the
host-side transceiver. COMRESET is followed by a COMINIT signal generated by the disc drive transceiver.
COMRESET and COMINIT are followed by an exchange of COMWAKE signals and Align primitives. The disc
drive will spin up after the successful exchange of Align primitives cause the PHY to come ready.
For more details, refer to:
• Section 6.8 of the Serial ATA 1.0 High-Speed Serialized AT Attachment specification
• Section 6.2 of the Serial ATA II: Extensions to Serial ATA 1.0 specification
• SATA 1.0 design guides
Note.These specifications and guides are available on the Serial ATA web site (www.serialata.org).

2.9.3Conducted noise
Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on
the +5 volt line.
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 10 MHz.
Note.Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write
current.
2.9.4Voltage tolerance
Voltage tolerance (including noise):
5V ± 5%
2.9.5Power-manageme nt modes
The drive provides programmable power management to provide greater energy efficiency. In most systems,
you 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 disc
access is necessary.
• Standby mode
The drive enters Standby mode when the host sends a Standby Immediat e c omma nd. If the ho st 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 tim er delay is established using a Standby or Idle command. In Sta ndby
mode, thedrive buffer is in Self Refresh Low Power mode, the heads are parked and the spindle is at rest.
The drive accepts all commands and returns to Active mode any time disc access is necessary.
• Sleep mode
The drive enter s S leep m ode after rece iv ing a Slee p com man d fro m th e ho st. In Sl eep mod e, th e dr ive buffer
is in Self Refresh 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 with all current translation parameters intact.
Momentus 7200.1 SATA Product Manual, Rev. B
11
• 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 disc access is necessary.

2.16Corrosive 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 electr onic dr i ve com ponen t reliab ilit y can be af fecte d by th e i nst allationenvironment. Th e si l-
ver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide,
chloride, and nitr ate c ont ami na nt s. S ulfur is found to be the m ost dam aging . In ad di tion, e lectron i c comp onent s
should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or

3.0Configuring and mounting the drive
This section contains the specifications and instructions for configuring and mounting the drive.
3.1Handling 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:
• Keep the drive in the electrostatic discharge (ESD) bag until you are ready for installation to limit the drive’s
exposure to ESD.
• Before handling the drive, put on a grounded wrist strap, or ground yourself frequently by touching the metal
chassis of a computer that is plugg ed into a grounded outlet. Wear a grounded wrist strap through out the entire
installation procedure.
• Handle the drive only by its edges or frame.
• The drive is fragile—handle it with care. Do not press down on the drive top cover.
• Always rest the drive on a padded, antistatic surface until you 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.

Momentus 7200.1 SATA Product Manual, Rev. B
3.2Configuring the drive
(
S
Each drive on the Serial ATA interface connects in a point-to-point configuration with the Serial ATA host
adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point
relationships. 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 sep a rate ports. This means both drives b ehave as if they are
Device 0 (master) devices.
Serial ATA drives ar e des ig ned f or e asy inst al lation wi th no jump ers, t erm in ator s, or other settin gs. It is not n ecessary to set any jumpers on this drive for proper operation. The jumper block adjacent to the signal connector
is for factory use only.

Figure 2. Serial ATA connectors
SATA Power
3.3Serial 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 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, you can connect the drive as illustrated in Figure 3.

3.4Drive mounting
You can mount the drive using four screws in the side-mounting holes or four screws in the bottom-mounting
holes. See Figure 4 for drive mounting di m ensions. Follow these i mpo rt ant mo unting pr ecauti o ns when mou nting the drive:
• Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling.
• Use only M3 UNC mounting screws.
• Do not overtighten the mounting screws (maximum torque: 4.0 inch-lb).
• Four (4) threads (0.080 inches) minimum screw engagement recommended.

4.3.3S.M.A.R.T. commands
S.M.A.R.T. provides near-term failure prediction for disc 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://seatools.seagate.com.
This drive is ship ped wi th S. M.A.R. T. features disabled. You must have a recent BIOS or so ft ware pa ckage 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.
