1.1  
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  
1.2  
Non-volatile cache (NVC)  
Momentus 5400.3 PSD SATA include a non-volatile cache feature. For a user to see the benefits of NVC, the  
host operating system must support the “Non-volatile cache” commands (B6h) and associated subcommands  
as specified in the ATA-8 specification. See Section 4.3 for the list of commands supported by Momentus  
5400.3 PSD SATA drives (including the Non-volatile cache commands).  
Non-volatile cache is designed to:  
• Improve performance  
• Provide power savings and battery life (in notebook systems)  
• Improve reliability  
• Reduce acoustic noise in some read/write operations  
Improve performance  
The non-volatile cache (NVC) improves performance by writing and reading to the non-volatile cache rather  
than waiting for the rotating media to complete spinning-up from sleep, standby, and hibernate modes. Perfor-  
mance improvements may also be seen from minimizing disc seeks and enabling more I/Os per second. The  
non-volatile cache also improves cold boot performance when used with operating systems designed to take  
advantage of this cache.

Momentus 5400.3 PSD SATA Product Manual, Rev. A  
             
Provide power savings and battery life  
NVC decreases power consumption by reducing the amount of time the discs are spinning in the HDA.  
Improve reliability  
Shock and vibration impacts during writes is negligible when writing to NVC memory. This results in an overall  
Annualized Failure Rate (AFR) of less than 0.50%.  
Reduced acoustics  
Reads and writes from NVC memory may occur without the acoustic impact of spinning media and actuator  
movement.

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 10. 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 5400.3 PSD 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.

Acoustics  
Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All mea-  
surements 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))

FCC verification  
These drives are intended to be contained solely within a personal computer or similar enclosure (not attached  
as an external device). As such, each drive is considered to be a subassembly even when it is individually mar-  
keted to the customer. As a subassembly, no Federal Communications Commission verification or certification  
of the device is required.  
Seagate Technology LLC has tested this device in enclosures as described above to ensure that the total  
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.  
If necessary, you should consult your dealer or an experienced radio/television technician for additional sug-  
gestions. You may find helpful the following booklet prepared by the Federal Communications Commission:  
How to Identify and Resolve Radio-Television Interference Problems. This booklet is available from the Super-  
intendent of Documents, U.S. Government Printing Office, Washington, DC 20402. Refer to publication num-  
ber 004-000-00345-4.

Environmental protection  
Seagate designs its products to meet environmental protection requirements worldwide, including regulations  
restricting certain chemical substances.  
2.15.1  
European Union Restriction of Hazardous Substances (RoHS)  
The European Union Restriction of Hazardous Substances (RoHS) Directive restricts the presence of chemical  
substances, including Lead (Pb), in electronic products effective July 2006.  
A number of parts and materials in Seagate products are procured from external suppliers. We rely on the  
rep-resentations of our suppliers regarding the presence of RoHS substances in these parts and materials. Our  
supplier contracts require compliance with our chemical substance restrictions, and our suppliers document  
their compliance with our requirements by providing material content declarations for all parts and materials for  
the disc drives documented in this publication. Current supplier declarations include disclosure of the inclusion  
of any RoHS-regulated substance in such parts or materials.  
Seagate also has internal systems in place to ensure ongoing compliance with the RoHS Directive and all laws  
and regulations which restrict chemical content in electronic products. These systems include standard operat-  
ing procedures that ensure that restricted substances are not utilized in our manufacturing operations, labora-  
tory analytical validation testing, and an internal auditing process to ensure that all standard operating  
procedures are complied with.  
2.16  
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 with no jumpers, terminators, or other settings. It is not nec-  
essary to set any jumpers on this drive for proper operation. The jumper block adjacent to the signal connector  
is for factory use only.

(factory use only)  
Figure 2. Serial ATA connectors  
3.3  
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).  
• Four (4) threads (0.080 inches) minimum screw engagement recommended.  
Measurements shown in Figure 4 are in inches.

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 inter-  
rupt. 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:

S.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 moni-  
tors 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 ) that elimi-  
H
nates unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:  
This drive is shipped with S.M.A.R.T. features disabled. You 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.
