7 sec  
Seek measurements are taken with nominal power at 25°C ambient  
temperature. All times are measured using drive diagnostics. Seek time  
specifications 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.  
Full-stroke seek time is one-half the time needed to seek from the first  
data cylinder to the maximum data cylinder and back to the first data  
cylinder. The full-stroke typical value is determined by averaging 100  
full-stroke seeks in both directions.

ST310014ACE Product Manual, Rev. D  
Note. These drives are designed to meet the seek times represented  
in this manual consistently. 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 com-  
mand overhead or measure logical seeks may produce results  
that vary from these specifications.  
1.7 Power specifications  
The drive receives DC power (+5V or +12V) through a four-pin standard  
drive power connector.  
1.7.1 Power consumption  
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 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  
The read/write actuator arm moves in a random seek mode, with 80%  
of the time spent seeking randomly among all the logical blocks, and  
20% of the time idle. The current is measured over a 10-second period.  
No data is read or written during this test.  
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  
The read/write actuator arm moves in a random read/write mode, with  
80% of the time spent seeking, reading, and writing randomly among  
all the logical blocks, and 20% of the time idle. The current is measured  
over a 10-second period.  
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

1.7.2 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 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 volt-  
age by the typical RMS read/write current.  
1.7.3 Voltage tolerance  
Voltage tolerance (including noise): 5V 5% and 12V 10%  
1.7.4 Power-management modes  
The drive provides programmable power management to provide great-  
er energy efficiency. In most systems, you can control power manage-  
ment through the system setup program. The drive features the following  
power-management modes:

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.  
1.8 Environmental tolerances  
1.8.1 Ambient temperature  
Ambient temperature is defined as the temperature of the environment  
immediately surrounding the drive. Actual drive case temperature should  
not exceed 65°C (149°F) within the operating ambient conditions. Rec-  
ommended measurement locations are shown in Figure 4 on page 19.  
Above 1,000 feet (305 meters), the maximum temperature is derated  
linearly to 112°F (44°C) at 10,000 feet (3,048 meters).

1.8.5 Shock  
All shock specifications assume that the drive is mounted securely with  
the input shock applied at the drive mounting screws. Shock may be  
applied in the X, Y or Z axis.  
1.8.5.1 Operating shock  
These drives comply with the performance levels specified in this docu-  
ment when subjected to a maximum operating shock of 63 Gs (based  
on half-sine shock pulses of 2 msec). Shocks should not be repeated  
more than two times per second.  
1.8.5.2 Nonoperating shock  
The nonoperating shock level that the drive can experience without  
incurring physical damage or degradation in performance when subse-  
quently put into operation is 350 Gs (based on nonrepetitive half-sine  
shock pulses of 1 and 2 msec duration).  
1.8.6 Vibration  
All vibration specifications assume that the drive is mounted securely  
with the input vibration applied at the drive mounting screws. Vibration  
may be applied in the X, Y or Z axis.

1.9 Drive acoustics  
Drive acoustics are measured as overall A-weighted acoustic sound  
power levels (no pure tones). All measurements are generally consistent  
with ISO document 7779. Sound power measurements were taken  
under essentially free-field conditions over a reflecting plane. For all  
tests, the drive was oriented with the cover facing upward.  
Note. For seek mode tests, the drive was 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)

1.12.2 Electromagnetic compatibility  
Hard drives that display the CE mark comply with the European Union  
(EU) requirements specified in the Electromagnetic Compatibility Direc-  
tive (89/336/EEC). Testing is performed to the levels specified by the  
product standards for Information Technology Equipment (ITE). Emis-  
sion levels are defined by EN 55022, Class B and the immunity levels  
are defined by EN 55024.  
Seagate® uses an independent laboratory to confirm compliance with  
the EC directives specified in the previous paragraph. Drives are tested  
in representative end-user systems. Although CE-marked Seagate  
drives comply with the directives when used in the test systems, we  
cannot guarantee that all systems will comply with the directives. The

2.0 Configuring and mounting the drive  
This section contains the specifications and instructions for configuring  
and mounting the drive.  
2.1 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:  
The SeaShellreplaces 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  
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 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.

ST310014ACE Product Manual, Rev. D  
2.2 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 2. 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  
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.  
   
ST310014ACE Product Manual, Rev. D  
2.3 Jumper settings  
17  
2.3.1 Master/slave configuration  
The options jumper block shown in Figure 2 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.  
Masteror 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.  
Set a jumper on pins 5 and 6 and a jumper on pins 7 and 8. Use this  
jumper setting only if the drive does not work as a master with no jumpers  
installed.

ST310014ACE Product Manual, Rev. D  
2.3.2 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  
3 on page 17. Refer to your computer manual to determine whether your  
computer supports this option.  
2.3.3 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.  
Notes:  
1. 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  
sensing 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).  
2. When using a 40-pin 80-conductor cable, attach the blue con-  
nector to the motherboard, the black connector to the master  
drive, and the grey connector to the slave.

2.1 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  
3 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. Insert the screws no more than  
0.20 inch (5.08 mm) into the bottom mounting holes and no more than  
0.14 inch (3.55 mm) into the side mounting holes.  
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.

3.1.4 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 monitors predetermined drive attributes  
thataresusceptibletodegradationovertime. Ifself-monitoringdetermines  
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-Rev 6 Standard.  
SeaTools diagnostic software activates a built-in drive self-test (DST)  
S.M.A.R.T. command for D4H that eliminates 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.
