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.

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 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 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.

• 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
10

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.

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:
• The SeaShell™ replaces electrostatic discharge (ESD) bags. The SeaShell package is a shock-ribbed,
transparent clamshell enclosure that limits a drive’s exposure to ESD and also protects against external
shocks and stresses. The design permits attaching cables, software loading and label/barcode scanning
without removing the drive from the SeaShell. This minimizes handling damage. Keep the drive in the Sea-
Shell 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 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
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.
Figure 1.
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—doing so voids the warranty.

Jumper settings
3.3.1
Master/slave configuration
The options jumper block shown in Figure 1 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.

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 1. 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 “F1H Report Full Capacity Available” causes Identify Data words 60 and 61 to report the full capacity.
See Section 4.1.3 on page 30 for more details on the Set Features command.
Barracuda 7200.7 Product Manual, Rev. E
19
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.
Master
Pin 1

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 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 1 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.

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-6 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:
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.
