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 and +12V) through a four-pin standard drive power connector.  
2.7.1  
Power consumption  
Power requirements for the drives are listed in the table on page 7. 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.  
• Operating power and current  
Operating power is measured using a standard Consumer Storage Profile.  
• 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  
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.

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:  
• Keep the drive in the electrostatic discharge (ESD) bag 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.

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, drive reliability may be compromised  
and could lead to permanent damage—doing so voids the warranty.

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 DiscWizardor 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 27 for more details on the Set Features command.  
DB35 Series Product Manual, Rev. B  
17  
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.

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 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.

Identify Device command  
The Identify Device command (command code ECH) transfers information about the drive to the host following  
power up. The data is organized as a single 512-byte block of data, whose contents are shown in the Table 6  
on page 22. All reserved bits or words should be set to zero. Parameters listed with an “x” are drive-specific or  
vary with the state of the drive. See Section 2.0 on page 3 for default parameter settings.  
The following commands contain drive-specific features that may not be included in 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:

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.

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
