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 normally 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 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 contains a set of registers that shadow the contents of the traditional device regis-  
ters, referred to as the Shadow Register Block. All Serial ATA devices behave like Device 0 devices. For addi-  
tional information about how Serial ATA emulates parallel ATA, refer to the “Serial ATA: High Speed Serialized

Seek time  
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 5,000 measurements of seeks between  
random tracks, less overhead.

Note. 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, 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.

Power specifications  
The drive receives DC power (+5V) through a native SATA power connector.  
2.9.1 Power consumption  
Power requirements for the drives are listed in the table 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 fromthe time ofpower-onto thetimethat the drive spindle reaches operating speed.  
• Seek mode  
During seek mode, the read/write actuator arm moves toward a specific position on the disc surface and does  
not execute a read or write operation. Servo electronics are active. Seek mode power is measured 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

Deferred spinup  
Momentus 5400.5 SATA drives do not support the deferred spinup option. If you require this option, refer to the  
Momentus 5400.3 SATA Blade Server family of drives.  
2.9.3  
Conducted 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.

Power-management 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 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 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 enters Sleep mode after receiving a Sleep command from the host. In Sleep mode, the drive 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.  
• 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.

Drive emission of sound is measured consistent with the ECMA-74 and its’ referenced standards. Testing is  
conducted at room temperature (approximately 25°C). Emission levels are reported as the total A-weighted  
sound power levels for steady state, idle, and active seek modes of operation.

*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 measurement and identification of PDTs. An exception to this pro-  
cess is the use of the absolute threshold of hearing. Seagate uses the lower limit for the threshold curve* 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.  
*Defined as the median curve given by ISO 389-7 (Tf curve) minus 10dB at all frequencies.

Free Fall Protection feature  
The Free Fall Protection feature provides enhanced data protection against shock events that may occur while  
the drive is operating. This feature is designed to decrease the likelihood of data loss by detecting a free fall  
event and unloading the actuator before a shock takes place in falls of >8 inches (nominal). The drive uses a 0  
G sensor mounted on the printed circuit board assembly (PCBA) to sense this event.  
To enable the Free Fall Protection feature on ST9160310ASG, ST9120310ASG, and ST980310ASG models,  
use Set Features command 41h. To disable this feature, use Set Features command C1h.

assembly (enclosure, disc drive, motherboard, power supply, etc.) does comply with the limits for a Class B  
computing device, pursuant to Subpart J, Part 15 of the FCC rules. Operation with noncertified assemblies is  
likely to result in interference to radio and television reception.  
Radio and television interference. This equipment generates and uses radio frequency energy and if not  
installed and used in strict accordance with the manufacturer’s instructions, may cause interference to radio  
and television reception.  
This equipment is designed to provide reasonable protection against such interference in a residential installa-  
tion. However, there is no guarantee that interference will not occur in a particular installation. If this equipment  
does cause interference to radio or television, which can be determined by turning the equipment on and off,  
you are encouraged to try one or more of the following corrective measures:  
• Reorient the receiving antenna.  
• Move the device to one side or the other of the radio or TV.  
• Move the device farther away from the radio or TV.  
• Plug the computer into a different outlet so that the receiver and computer are on different branch outlets.

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 corro-  
sive chemicals as electronic drive component reliability can be affected by the installation environment. The sil-  
ver, 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 vulca-  
nized 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.

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 dis-  
charge (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 plugged into a grounded outlet. Wear a grounded wrist strap throughout 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.

3.2  
Configuring the drive  
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 separate ports. This means both drives behave as if they are  
Device 0 (master) devices.  
Serial ATA drives are designed for easy installation. It is normally not necessary to set any jumpers on this  
drive for proper operation. If the host system does not support SATA 3Gb/s operation, place a jumper on pins 1  
and 2 to limit the drive to 1.5Gb/s operation.

Serial ATA cables and connectors  
The Serial ATA interface cable consists of four conductors in two differential pairs, plus three ground connec-  
tions. 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.

Drive 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 dimensions. Follow these important mounting precautions when mount-  
ing 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 (0.4519 N-m).  
• Four (4) threads (0.080 inches, 2.032 mm) minimum screw engagement recommended.  
• Avoid excessive drive distortion when mounting. Refer to the following specifications for stiffness/deflection
