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 necessary to set any jump-  
ers 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 or +12V) through a native SATA power connector. See Figure 4, page 22 on  
3.8.1  
Power consumption  
Power requirements for the drives are listed in the table on page 9. 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.  
• 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 mode.

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 10 MHz.  
• 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  
PowerChoiceTM power management  
Drives using the load/unload architecture provide programmable power management to tailor systems for per-  
formance and greater energy efficiency.  
The table below lists the supported PowerChoice modes. The further you go down in the table, the more power  
savings you get. For example, Idle_B mode results in greater power savings than Idle_A mode. Standby mode  
results in the greatest power savings.

Reduced electronics  
Heads unloaded. Disks spinning at full RPM  
Heads unloaded. Disks spinning at reduced RPM  
Heads unloaded. Motor stopped (disks not spinning)  
PowerChoice can be invoked using one of these two methods:  
• Extended Power Conditions (EPC) Set Features Command method-Enable and initialize the idle condition  
timers.  
• Standby Immediate and Idle Immediate command method-Use the EPC Set Features Command. This allows  
the host to directly transition the drive to any supported PowerChoice mode. The drive preserves the existing  
idle power settings.  
PowerChoice reporting methods  
PowerChoiceTM provides these reporting methods for tracking purposes:  
Check Power Mode Reports  
• Current power condition  
Power Condition Log Reports  
• Idle condition enabled/disabled  
• If timer is changeable  
• Typical recovery time from extended power conditions  
• Current timer setting and Manufacturer default timer settings

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)

Reliability  
3.12.1  
Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)  
The product shall achieve an Annualized Failure Rate - AFR - of 0.73% (Mean Time Between Failures - MTBF  
- of 1.2 Million hours) when operated in an environment that ensures the HDA case temperatures do not  
exceed 40°C. Operation at case temperatures outside the specifications in Section 3.9 may increase the prod-  
uct Annualized Failure Rate (decrease MTBF). AFR and MTBF are population statistics that are not relevant to  
individual units.  
AFR and MTBF specifications are based on the following assumptions for business critical storage system  
environments:  
• 8,760 power-on-hours per year.  
• 250 average motor start/stop cycles per year.  
• Operations at nominal voltages.  
• Systems will provide adequate cooling to ensure the case temperatures do not exceed 40°C. Temperatures  
outside the specifications in Section 3.9 will increase the product AFR and decrease MTBF.

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.

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, chlo-  
ride, 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.  
4.1  
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:  
• 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 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 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.  
4.2  
Configuring the drive  
Each drive on the Serial ATA interface connects point-to-point with the Serial ATA 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 Serial ATA 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.  
Serial ATA drives are designed for easy installation. It is usually not necessary to set any jumpers on the drive  
for proper operation; however, if you connect the drive and receive a “drive not detected” error, your SATA-  
equipped motherboard or host adapter may use a chipset that does not support SATA speed autonegotiation. If  
you have a motherboard or host adapter that does not support autonegotiation:  
• Install a jumper as shown in Figure 3, page 22 below to limit the data transfer rate to 1.5 Gbits per second  
(and leave the drive connected to the SATA-equipped motherboard or host adapter that doesn’t support  
autonegotiation) or  
Constellation Serial ATA Product Manual, Rev. D  
21  
                       
• Install a SATA host adapter that supports autonegotiation, leave the drive jumper block set to “Normal  
operation” (see Figure 3, page 22 below), and connect the drive to that adapter. This option has the benefit of  
not limiting the drive to a 1.5 Gbits/sec transfer rate.

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 5  
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 4, page 22.

Each cable is keyed to ensure correct orientation. Constellation Serial ATA drives support latching SATA con-  
nectors.  
4.4  
Drive mounting  
You can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the  
bottom-mounting holes. See Figure 5, page 23 for drive mounting dimensions. Follow these important mount-  
ing precautions when mounting the drive:  
• Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling as  
a guideline. Please refer to Section 4.5 for final cooling requirements.  
• Use only M3 x 0.5 metric mounting screws.  
• Four (4) threads (0.080 inches) minimum screw engagement recommended. Also ensure maximum screw  
length does not bottom out in mounting holes.  
• Do not overtighten the mounting screws (maximum torque: 4.5 inch-lb, ± 0.45 in-lb).

Cooling  
Cabinet cooling must be designed by the customer so that the ambient temperature immediately surrounding  
the drive will not exceed temperature conditions specified in Section 3.9.1, "Ambient temperature."  
The rack, cabinet, or drawer environment for the drive must provide heat removal from the electronics and  
head and disc assembly (HDA). You should confirm that adequate heat removal is provided using the temper-  
ature measurement guidelines described in Section 3.9.1.  
Forced air flow may be required to keep temperatures at or below the temperatures specified in Section 3.9.1  
in which case the drive should be oriented, or air flow directed, so that the least amount of air flow resistance is  
created while providing air flow to the electronics and HDA. Also, the shortest possible path between the air  
inlet and exit should be chosen to minimize the travel length of air heated by the drive and other heat sources  
within the rack, cabinet, or drawer environment.  
If forced air is determined to be necessary, possible air-flow patterns are shown in Figure 6, page 24. The air-  
flow patterns are created by one or more fans, either forcing or drawing air as shown in the illustrations. Con-  
duction, convection, or other forced air-flow patterns are acceptable as long as the temperature measurement  
guidelines of Section 3.9.1 are met.

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.
