2.7 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 rand om average of at least 5,000 measure ments of seeks between
random tracks, less overhead.

*Typical seek times (msec) Read Write

Track-to-track <1.0 <1.2
Average 8.5 9.5
Average latency: 4.16 4.16

*Measured in performance mode .
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.

2.9 Power specifications

The drive receives DC power (+5V or +12V) through a four-pin standard drive power connector.

2.9.1 Power consumption

Power requirements for the drives are listed in the table on page 8. Typical power measurements are based on
an average of drives tested, under nomi nal conditions, using 5.0 V and 12.0V input vo ltage 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 operatio n. Serv o electr onics ar e active. S eek mode power repres ents the worst­case power consump tion, using only random se eks with read or write laten cy time. This mode is not typic al
and is provided for worst-case information.

• Read/write power and current

Read/write power is mea sured with the he ads on track, base d on a 16-secto r 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 mea sure d using 40 percent random s eek s, 40 p erce nt r ead /write mod e ( 1 wri te fo r e ach
10 reads) and 20 percent drive idle mode.

• Idle mode power

Idle mode power is measur ed wi th th e driv e up to s pee d, wi th ser vo ele ctron ics act ive and with the heads in
a random track location.

• Standby mode

During Standby mode, the driv e accepts commands, but the dr ive is not spinning, and the ser vo and read/
write electronics are in power-down mode.

Power dissipation (watts)
Example: ST3160021A, 2-disc

Spinup — — 2.8 (peak)
Idle 7.5 0.482 0.424
Idle* (with offline activity) 9.3 0.587 0.530

2.9.2 Conducted noise

Input noise ripple is mea su red at the ho st system power supply acr o ss an equ iv alent 80 -o hm r es isti ve 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 expect ed to ope rate wi th a max imum of 10 0 mV pe ak-t o-peak s quare- wave
injected noise at up to 10 MHz.

Note. Equivalent r esistance is calculated by dividing the nominal volta ge by the typical RMS read/wr ite

current.

2.9.3 Voltage tolerance

Voltage tolerance (including noise):

5V ± 5%
12V ± 10%

2.9.4 Power-management modes

The drive provides programmab le power mana gement to provide grea ter 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 Heads Spindle Buffer

Active Tracking Rotating Enabled
Idle Tracking Rotating Enabled
Standby Parked Stopped Enabled
Sleep Parked Stopped Disabled

• Active mode

The drive is in Active mode during the read/write and seek operations.

• Idle mode

The buffer remains en abled, and the drive a ccepts a ll comm ands and re turns to Ac tive 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 dri ve can also enter Stand by mode automaticall y after the drive has be en 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 a t 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 he ads are p arke d and the spind le is at rest. T he dr ive leav es Slee p mo de after it rece ives 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 perfo rms an Active function (read, wr ite or seek), the standby time r is reinitialized and
begins counting down from its specified delay times to zero. If the standby timer reaches zero before any drive

10 Barracuda 7200.7 Product Manual, Rev. N

activity is required, the driv e makes a transi tion to Standb y mode. In both Idle and Standby mode, the d rive
accepts all commands and returns to Active mode when disc access is necessary.

2.15 Environmental protection

Seagate designs its prod ucts to meet environ mental protectio n requirem ents worldwide, in cluding regul ations
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 Restri ction of Hazardous Substances (RoH S) Direc ti ve ha ve not bee n fin ali z ed, to th e bes t
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 Seag ate products are procured from external suppl iers. We rely on the
rep-resentations of our suppliers regarding the presence of RoHS substances in these parts and materials. Our
supplier contracts re quire compliance with our chem ical substance restrictions, a nd 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 procedur es that e nsure that restric ted substances are no t utilized in our manufactu ring op erations,
labora-tory analyti cal validatio n testing, and an internal auditing pr ocess to ens ure that all standar d operatin g
procedures are complied with.

2.16 Corrosive environment

Seagate electronic driv e components pass accelerated corr osion testing equivalent to 10 ye ars exposure to
light industrial envir onments containi ng sulfuro us gases, chlorine an d 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 elec tronic drive componen t reliabi lity ca n be affected by th e installati on environm ent. The s ilver,
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, electr onic components
should never be ex pose d to c ondensin g water on the surfac e of th e pri nted cir cuit bo ard a ssembly (PCBA ) or
exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulca­nized rubber, that can outgas corr osive compoun ds should be m inimized or e liminated. Th e 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 Handling and static discharge precautions

After unpacking, and before installation, the dr ive may be ex posed to pote ntial handli ng and electros tatic dis­charge (ESD) hazards. Observe the following standard handling and static-discharge precautions:

Caution:

• The SeaShell™ replaces electrostatic discharge (ESD) bags. The SeaShell package is a shock-ribbed,
transparent clamshell enclosure that limits a drive’s exposu re to ESD and also protects agains t external
shocks and st resses. The design permits attaching cables, software loading and labe l/barcode scanning
without removing the driv e fr om the SeaSh ell. Th is mi nimi zes handli ng dam age. K eep the drive in the Sea­Shell package until you are ready for installation.

• Before handling the drive, put on a grounded wrist strap, or ground yourself frequently by touching the metal
chassis of a com puter that is plugge d into a grounded outl et. Wear a grounded wris t strap throughout th e
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 co ntain in for ma tio n nee ded to service the drive . Ot her l abe ls ar e

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 d isc drives. Prop er precautions should be taken to en sure full functio nality and preven t
possible damage to the drive.

Breather Hole

Do not cover
or seal.

Figure 3. Breather filter hole location

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

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—doing so voids the warranty.

3.3 Jumper settings

rd

3.3.1 Master/slave configuration

The options jumper b lock shown in Figure 1 is used to configure the drive for operatio n. It is the 8-pin dual
header between the in terface connec tor and the power connector. Use the following settings to con figure the
drive as a master or a slave.

Master or single drive. The drive is configured at the factor y for a master or single-drive operation with a
jumper set on pins 7 and 8.

3.3.2 Cable-select option

Computers that use cable select det ermine the master and slave drives by selecting or dese lecting pin 28,
CSEL, on the interface bus. Master and slav e dr ives are det ermi ned by their phys ical pos i tio n on the cab le. To
enable cable selec t, set a jumper on pins 5 and 6 as shown i n Figure 1. Refer to your computer manual to
determine whether your computer supports this option.

3.3.3 Alternate capacity jumper

Some older comput ers may “hang ” at startup if their B IOS de tects a disc drive with a ca pacity gre ater than 3 2
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 capacitie s greater than 32 Gbytes, the al ternate capacity jumper changes the total available
LBA sectors to 32 Gb ytes to solve is sues with some BI OS during power on . The ATA Set Features subc om­mand “F1

Report Full Capacity Avai lable” causes Identif y Data words 60 and 61 to r eport the full capacity.

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 even­numbered conductors connected to the ground pins to improve signal integrity.

Note. If you are using a 40-pin, 80-conducto

cable, attach the blue connector to the

Figure 1. Ultra ATA cable connectors

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 detec ts the 80-conduc tor cable by sens­ing a capacitor at the host side thr ough the CBLID– signal. The result is repor ted 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 driv e in any o rientation u sing four s crews in the side -mountin g holes or four screws i n the
bottom-mounting holes. See Figure 1 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.

• 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.

4.0 ATA interface

These drives use t he industry-standard ATA task file interface that s upports 16-bit data transfer s. It supports
ATA programmed input/output (PIO) modes 0–4; m ultiwor d DMA m odes 0– 2, and Ul tra DMA mod es 0–5. The
drive also supports the use of the IORDY signal to provide reliable high-speed data transfers.

You can use a daisy-chai n cabl e to co nnect two drive s to a single AT host bus. For detailed i nform ation abou t
the ATA interface, re fer to the draft of AT Attachment with Packet Interface Extension (ATA/ATAPI-6), NCITS
T13 1410D, subsequently referred to as the Draft ATA-6 Standard.

4.1 ATA interface signals and connector pins

Figure 1 on page 26 summarizes the signal s on the ATA interface connector that the drive supports. For a
detailed description of these signals, refer to the Draft ATA-6 Standard.

S.M.A.R.T. provides near-term failure pred iction for disc drives. When S.M .A.R.T. is enabled, the drive moni­tors predetermined driv e attr i bute s tha t are susceptible t o d egrad ati on ov er time. If self-mon ito ring de ter mines
that a failure is likely, S.M.A.R.T. makes a status report a vailable to the host. Not a ll failures are predi ctable.
S.M.A.R.T. predictability is limite d to the attributes the dr ive can monitor. For more information on S.M.A.R.T.
commands and implementation, see the Draft ATA-6 Standard.
