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 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 additi o n, Seri al ATA ma kes the tra nsition fr om P a rall el ATA easy b y pro v iding leg acy softwar e sup port . 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 operatin g 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 Seri al ATA host ada pter cont ains a set of registe rs that sha dow the conte nt s of the trad iti onal devic e regi s-

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

AT Attachment” specification. The specification can be downloaded from www.serialata.org.

2.6 Seek tim e

Seek mea surem ent s a re t ake n w ith nom inal po wer a t 25 °C ambient t empe ratur e. All tim es a re m easu red 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 drive s ar e de si gned to consisten tl y me et t he se ek t imes r epr esente d in thi s manu al. P hysical

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.

2.7 S tart/stop times

2.8 Power specifications

The driv e receives DC po wer ( + 5V or + 12V ) t hrou gh a nat ive S ATA power connector. See Figu re 4 on p age 26.

2.8.1 Power consumption

Power requir emen ts fo r the driv e s are lis ted in the t able on page 9. Typical powe r measu rem ent s are ba sed 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.

• 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 represents the

worst-case power consumption, using only random seeks w ith read or write latency time. This mode is not

typical and is provided for worst-case information.

• Read/write power and current

Read/write power is measured with the heads on track, based on a 16-sector write followed by a 32-msec

delay, then a 16-sector read followed by a 32-msec delay.

Typical seek times (msec) Read Write

Track-to-track <0.8 <1.0

Average <11.0 <12.0

Average latency: 4.16 4.16

Power-on to Ready (sec) 16 (max)

Standby to Ready (sec) 16 (max)

Ready to spindle stop (sec) 10 (max)

DB35.3 Series Serial ATA Product Manual, Rev. D

• Operating power and current

Operati n g powe r is measure d using 40 p ercent ran dom seeks, 4 0 per cent r ead/ writ e mode ( 1 w rite for each

10 reads) and 20 percent drive idle mode.

• I dle mode power

Idle mode power is measu red w ith t he dr ive up to speed, with servo electron ics ac tive and with the he ads 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 mode.

2.8.2 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 powe r, the drive is expect ed to oper ate with a maxi m um of 120 mV peak-to -pea k 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.

2.8.3 Voltage tolerance

Voltage tolerance (including noise):

5V ± 5%

12V ± 10%

2.8.4 Powe r- manag eme 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.

Power modes Heads Spindle Buffer

Active Tracking Rotating Enabled

Idle Tracking Rotating Enabled

Standby Parked Stopped Enabled

Sleep Parked Stopped Disabled

DB35.3 Series Serial ATA Product Manual, Rev. D

• I dle 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 enabled, 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 disabled, 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.

2.9 Environm ental spec ificatio ns

2.9.1 Ambient temperature

Ambient temperature is defined as the temperature of the environment immediately surrounding the drive.

Actual drive case temperature should not exceed 75°C (167°F) within the operating ambient conditions. Rec-

ommended measurement locations are shown in Figure 5 on page 27.

Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet

2.10 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)

2.14.1 European Union Restriction of Hazardous Substances (RoHS) Directive

Seagate designs its products to meet environmental protection requirements worldwide, including regulations

restricting certain chemical substances. A new law, the European Union Restriction of Hazardous Substances

(RoHS) Directive, restricts the presence of chemical substances, including Lead, Cadmium, Mercury,

Hexavalent Chromium, PBB and PBDE, in electronic products, effective July 2006. This drive is manufactured

with components and materials that comply with the RoHS Directive.

2.14.2 China Restriction of Hazardous Substances (RoHS) Directive

This product has an Environmental Protection Use Period (EPUP) of 20 years. The following

table contains information mandated by China's "Marking Requirements for Control of Pollution

Caused by Electronic Information Products" Standard.

"O" indi cates the hazardous and toxic subst ance content of t he p a rt (at the hom ogeno us m ater ial level) is lower

than the threshold defined by the China RoHS MCV Standard.

"X" indicates the hazardous and toxic substance content of the part (at the homogenous material level) is over

the threshold defined by the China RoHS MCV Standard.

2.15 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, nicke l and gold film s used in Seag ate pr oduct s are especially sen sitiv e to the p resen ce of sulfide, chl o-

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 a n am bient relat ive hum i dity gr eate r th an 9 5%. Materials used in cabin et fa bri cation , such as v ul ca-

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.

3.0 Configuring and mounting the drive

This section contains the specifications and instructions for configuring and mounting the drive.

3.1 Hand ling and static- disc harge pre cautions

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.

DB35.3 Series Serial ATA Product Manual, Rev. D

3.2 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 operatin g 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 mo ther boar d or hos t ada pter may use a ch ip se t tha t do es no t supp ort SATA speed au toneg otiation . If

you have a motherboard or host adapter that does not support autonegotiation:

• Install a jumper as shown in Figure 3 below to limit the data transfer rate to 1.5 Gbits per second (and leave

the dri ve conne cted to the SATA-e quipped mo therboard or host adapte r that doe sn’t support autonegotiat ion)

• Install a SATA host adapter that supports autonegotiation, leave the drive jumper block set to “Normal

operation” (see Figure 3 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.

Figure 3. Serial ATA connectors

3. 3 Seri al ATA ca bles and con nectors

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 8

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.

3.4 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 on page 27 for drive mounting dimensions. Follow these important

mounting 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.

• Use only 6-32 UNC mounting screws.

• The screws should be inserted no more than 0.150 inch (3.81 mm) into the bottom or side mounting holes.

• Do not overtighten the mounting screws (maximum torque: 6 inch-lb).

4.0 Ser ia l ATA (S ATA) interf a ce

These drives use the industry-standard Serial ATA interface that supports FIS data transfers. It supports ATA

programmed input/output (PIO) modes 0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–6.

For detailed information about the Serial ATA interface, refer to the “Serial ATA: High Speed Serialized AT

Attachment” specification.

4.1 Hot-Plug compatibility

DB35.3 Series Serial ATA drives incorporate connectors which enable you to hot plug these drives in accor-

dance with the Serial ATA II: Extension to Serial ATA 1.0a specification. This specification can be downloaded

from www.serialata.org.

DB35.3 Series Serial ATA Product Manual, Rev. D

4.2 Serial ATA device plug connector pin definitions

Table 8 summarizes the signals on the Serial ATA interface and power connectors..

Notes:

1. All pins are in a single row, with a 1.27 mm (0.050”) pitch.

2. The comments on the mating sequence apply to the case of backplane blindmate connector only. In this

case, the mating sequences are:

• the ground pins P4 and P12.

• the pre-charge power pins and the other ground pins.

• the signal pins and the rest of the power pins.

3. There are three power pins for each voltage. One pin from each voltage is used for pre-charge when

installed in a blind-mate backplane configuration.

4. All used voltage pins (Vx) must be terminated.

4.3.3 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 D4H) that elimi-

nates unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:

http://seatools.seagate.com.

This dr i ve is shipped with S. M.A .R.T. features di sab led. You must ha ve a r ecent BI OS or so ftware 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
