1.5 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.


•

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.

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.

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

During seek mode, the read/write actuator arm moves toward a specific position on the disc surface and does not execute a read or

8 Barracuda ATA II 100 Family Product Manual, Rev. A 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 inactive.

•

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 powerdown mode.

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 voltage by the typical RMS read/write current.

1.7.4 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 Modes Heads

Spindle

Rotating

Rotating

Parked Stopped

Stopped

Buffer

Enabled

Enabled

Enabled

Disabled

•

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.

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 69°C (156°F) within the operating ambient conditions. Recommended measurement locations are shown in Figure 3 on page 20.

Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet (3,048 meters).

1.12 Agency certification

1.12.1 Safety certification

The drives are recognized in accordance with UL 1950 and CSA C22.2

(950) and meet all applicable sections of IEC950 and EN 60950 as tested by TUV North America.

1.12.2 Electromagnetic compatibility

Hard drives that display the CE mark comply with the European Union

(EU) requirements specified in the Electromagnetic Compatibility Directive (89/336/EEC). Testing is performed to the levels specified by the product standards for Information Technology Equipment (ITE). Emission 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 drive is designed for operation inside a properly designed enclosure, with properly shielded I/O cable (if necessary) and terminators on all unused I/O ports. Computer manufacturers and system integrators should confirm

EMC compliance and provide CE marking for their products.

Australian C-Tick (N176)

If these models have the C-Tick marking, they comply with the Australia/

New Zealand Standard AS/NZS3548 1995 and meet the Electromagnetic Compatibility (EMC) Framework requirements of the Australian

Communication Authority (ACA).

1.12.3 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 marketed to the customer. As a subassembly, no Federal Communications

Commission verification or certification of the device is required.

Seagate Technology, Inc. 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 installation. 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 suggestions. 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 Superintendent of Documents,

U.S. Government Printing Office, Washington, DC 20402. Refer to publication number 004-000-00345-4.


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 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

SeaShell package until you are ready for installation.

•

The drive has a cover called SeaShield .

Do not remove this permanent cover—it protects the drive from electrostatic discharge (ESD) and minor impact damage. The SeaShield cover also includes installation instructions and jumper settings. Removing the SeaShield voids the warranty.

•

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 factoryinstalled labels contain information needed to service the drive. Other labels are used to seal out dirt and contamination.


2.2 Jumper settings

2.2.1 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.

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.

Figure 2. Master/slave jumper settings

Circuit Board


2.2.2 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

2 on page 18. Refer to your computer manual to determine whether your computer supports this option.

2.2.3 Alternate capacity jumper

Some older computers may “hang” if their BIOS detects a hard drive that has more than 4,092 cylinders at startup. To eliminate this problem, the drive includes a capacity-limiting jumper that sets the drive’s default translation geometry to 4,092 cylinders (2.1 Gbytes). To realize the full capacity of the drive, you can use third-party software such as DiskWizard.

2.2.4 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.

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

connector 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 sidemounting holes or four screws in the bottom-mounting holes. See Figure

3 on page 20 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.


•

The screws should be inserted no more than 0.200 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.

3.0 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-5),

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 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.
