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 ran-

dom 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 val-

ues. 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.

2.8

Power specifications

The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 3 on page 20.

2.8.1 Power consumption and DC power requirements

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 tempera-

ture.

• Spinup power

Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating

speed.

• 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.

• Operating

Operating power is measured by simulating a typical PVR operating environment, using a 50% write 50% read

algorithm.

• 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 power, the drive is expected to operate with a maximum of 120 mV peak-to-peak square-wave

injected noise at up to 10MHz.

• 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 10MHz.

Note. Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.

2.8.3

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-man-

agement modes:

Power modes

Heads

Spindle

Rotating

Stopped

Buffer

Tracking

Parked

Enabled

Enable

Idle

Standby

Sleep

Enabled

Disabled

• 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 spec-

ifiable 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 com-

mands 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.

Test for Prominent Discrete Tones (PDTs)

Seagate follows the ECMA-74 standards for measurement and identification of PDTs. An exception to this process

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.

tives when used in the test systems, we cannot guarantee that all systems will comply with the directives. The drive

is designed for operation inside a properly designed enclosure, with properly shielded I/O cable (if necessary) and

terminators on all unused I/O ports. Computer manufacturers and system integrators should confirm EMC compli-

ance and provide CE marking for their products.

2.13.3

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 marketed to

the customer. As a subassembly, no Federal Communications Commission verification or certification of the device

is required.

Seagate 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 installation.

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 sugges-

tions. 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 Superintendent of

Documents, U.S. Government Printing Office, Washington, DC 20402. Refer to publication number 004-000-

00345-4.

Environmental protection

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

restricting certain chemical substances.

2.14.1

European Union Restriction of Hazardous Substances (RoHS) Directive

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 Direc-

tive.

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" indicates the hazardous and toxic substance content of the part (at the homogenous material 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 cau-

tion 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, chloride, and nitrate contaminants.

Sulfur is found to be the most damaging. In addition, electronic components should never be exposed to condens-

ing 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 vulcanized rubber, that can outgas corrosive com-

pounds should be minimized or eliminated. The useful life of any electronic equipment may be extended by replac-

ing 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 discharge

(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.

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 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.

3.3

Serial 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 8 for connec-

tor 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.

SV35 Series SATA Product Manual, Rev. D

Figure 3. Attaching SATA cabling

Signal connector

Power connector

Each cable is keyed to ensure correct orientation. SV35 Series SATA drives support latching SATA connectors.

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 bot-

tom-mounting holes. See Figure 4 for drive mounting dimensions. Follow these important mounting precautions

when mounting the drive:

• Allow a minimum clearance of 0.030 inches (0.76mm) 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 (3.81mm) into the bottom or side mounting holes.

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

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 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 D4 ) 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 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.
