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 or exceed 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 four-pin standard drive power connector.

2.8.1 Power consumption

Power requirements for the drives are listed in the table on page 12. 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 ambi-

ent 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 represents the worst-

case power consumption, using only random seeks with 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.

• Operating power and current

Operating power is measured using 40 percent random seeks, 40 percent read/write mode (1 write for each

10 reads) and 20 percent drive idle mode.

• 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 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

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:

Power mode

Active

Heads

Spindle

Rotating

Stopped

Buffer

Tracking

Parked

Enabled

Disabled

Idle

Standby

Sleep

• 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 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.

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.

2.14

Environmental protection

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

restricting certain chemical substances.

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. Although amendments to the Euro-

pean Union’s Restriction of Hazardous Substances (RoHS) Directive have not been finalized, to the best of our

knowledge the disc drives documented in this publication will comply with the final RoHS Directive require-

ments.

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.

2.15

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, 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.

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:

• 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.

Barracuda 7200.8 PATA Product Manual, Rev. F

3.2

Breather filter hole precautions

This section contains information regarding the precautions which should be taken regarding the breather filter

hole in Seagate hard disc drives. Proper precautions should be taken to ensure full functionality and prevent

possible damage to the drive.

Breather hole

Do not cover or seal

this hole.

Figure 3

Breather filter hole location

Caution: Do not cover, seal, or insert any object into this hole.

This hole has two purposes:

• To allow condensation inside the hard disc to escape

• To allow air pressure inside the hard disc to equalize with ambient pressure

Note. If this hole is covered, sealed, or penetrated by any object, the drive reliability may be compromised

and could lead to permanent damage. Covering or sealing this hole voids the warranty.

Jumper settings

3.3.1

Master/slave configuration

The options jumper block shown in Figure 4 is used to configure the drive for operation. It is the 8-pin dual

header between the interface connector and the power connector. Use the following settings to configure the

drive as a master or a slave.

Master or single drive. The drive is configured at the factory for a master or single-drive operation with a

jumper set on pins 7 and 8.

Drive as slave. Remove all jumpers.

Drive as master with a non-ATA-compatible slave.

Use this jumper setting only if the drive does not work as a master with no jumpers installed.

3.3.2

Cable-select option

Computers that use cable select determine the master and slave drives by selecting or deselecting pin 28,

CSEL, on the interface bus. Master and slave drives are determined by their physical position on the cable. To

enable cable select, set a jumper on pins 5 and 6 as shown in Figure 4. Refer to your computer manual to

determine whether your computer supports this option.

3.3.3

Alternate capacity jumper

Some older computers may “hang” at startup if their BIOS detects a disc drive with a capacity greater than 32

Gbytes. This limits the drive’s capacity to 32 Gbytes when the alternate capacity jumper is used. To access the

full capacity of the drive, you can:

• Update the BIOS

• Use third-party software such as DiscWizard^™or Disk Manager

• Use a third-party host adapter

For drives with capacities greater than 32 Gbytes, the alternate capacity jumper changes the total available

LBA sectors to 32 Gbytes to solve issues with some BIOS during power on. The ATA Set Features subcom-

mand “F1 Report Full Capacity Available” causes Identify Data words 60 and 61 to report the full capacity.

See Section 4.1.3 on page 33 for more details on the Set Features command.

Windows XP, Windows Me, Windows 98 or newer versions are needed to support drives with capacities

greater than 32 Gbytes.

3.3.4

Ultra ATA/100 cable

An 80-conductor 40-pin cable is required to run Ultra DMA mode 3, mode 4, and mode 5. This cable uses

even-numbered conductors connected to the ground pins to improve signal integrity.

Note.

If you are using a 40-pin, 80-conductor

cable, attach the blue connector to the

motherboard, the black connector to the

master drive, and the gray connector

to the slave.

Note. The drive supports both host and drive cable detection. The host detects the 80-conductor cable by

sampling pin 34, CBLID–, on the interface bus. The drive detects the 80-conductor cable by sens-

ing a capacitor at the host side through the CBLID– signal. The result is reported in a Fast Rise

Detected bit (bit 13 of word 93 in the Identify drive parameter block).

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 6 for drive mounting dimensions. Follow these important mounting precau-

tions 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.

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

• Do not use a drive interface cable that is more than 18 inches long.

ATA interface

These drives use the industry-standard ATA task file interface that supports 16-bit data transfers. It supports

ATA programmed input/output (PIO) modes 0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–5. The

drive also supports the use of the IORDY signal to provide reliable high-speed data transfers.

You can use a daisy-chain cable to connect two drives to a single AT host bus. For detailed information about

the ATA interface, refer to the draft of AT Attachment with Packet Interface Extension (ATA/ATAPI-7), NCITS

T13 1410D, subsequently referred to as the Draft ATA-7 Standard.

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:

Enable write cache (default).

Set transfer mode (based on value in Sector Count register).

Sector Count register values:

Set PIO mode to default (PIO mode 2).

Set PIO mode to default and disable IORDY (PIO mode 2).

4.1.4

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-7 Standard.

SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4 ) that elimi-

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

http://seatools.seagate.com.

Barracuda 7200.8 PATA Product Manual, Rev. F

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.
