2.7 Seek time

Seek measurements are taken with nominal power. All times are measured using drive diagnostics. The sp ec ifications 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 speci fications.

2.9 Power specifications

The drive receives DC power (+5V) through the interface connector.

2.9.1 Power consumption

Power requirements for the drives are listed in the table below. 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 towar d a specific position on the disc surface and do es not execute a read or write operation. Servo electron ics a re active . Seek m ode p ower is measur ed based on three random seek operations every 100 msecs. This mode is not typical.

• Read/write power and current Read/write power is measured with the heads on track, based on three 63 sector read or write operations

every 100 msecs.

• 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.

Figure 1. Typical 5V startup and operation cu rre nt profile

2.9.2 Conducted noise

Input noise ripple is measured at the host system powe r supply across an equivalent 15-ohm resistive load on the +5 volt line.

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 cur-

rent.

EE25.2 Series Product Manual, Rev. E 17

2.9.4 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 Buffer Std timing

Active (operating) Tracking Rotating Enabled Idle, performance Tracking Rotating Enabled Idle, active Floating Rotating Disabled 100ms Idle, low power Parked Rotating Disabled 5.00 secs Standby Parked Stopped Disabled Set by host Sleep Parked Stopped Disabled Set by host

• 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 comman d. 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 comma nd 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.

2.16 Environmental protection

Seagate designs its products to meet environme ntal protection requirements worldwide, including regulations restricting certain chemical substances.

2.16.1 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.

A number of parts and materials in Seagate products are procured from external suppliers. We rely on the representations of our suppliers regarding the presence of RoHS substances in these parts and materials. Our supplier contracts require compliance with our che mical substance restrictions, and our suppliers document their compliance with our requirements by providing material conten t declarations for all p arts 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 on going compliance with the RoHS Directive and all laws and regulations which restrict chemical content in electronic products. These systems include standard operat-ing procedures that ensure that restricted substances are not utilized in our manufacturing operations, labora-tory analytical validation testing, and an internal auditing process to ensure that all standard operating procedures are complied with.

2.17 Corrosive environment

Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing cannot duplicate every potential application environment.

Users should use caution exposin g any electronic c omponents to uncontrolled chemical pollutants and corrosive chemicals as electronic drive component reliability can be affected by the installation environment. The silver, 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 da maging. In addi tion, electronic comp onent s should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should be minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives.

• The drive is 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 Drive mounting

You can mount the drive using four screws in the side-mounting holes or four screws in the bottom-mounting holes. See Figure 2 for drive mounting dimensions (dimensions in inches with mm in parentheses). Follow these important mounting precautions when mounting the drive:

• Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire pe rimeter of the drive for cooling.

• Use only M3 x 0.5 mounting screws.

• Do not overtighten the mounting screws (maximum torque: 4.0 inch-lb).

• Four (4) threads (0.080 inches) minimum screw engagement recommended.

• If mounting drive using the bottom holes, ensure the coplanarity of the mating surface is 0.010 inches or less.

SATA interface connector

See Section 3.4.1 beginning on page 30 for SATA drives. See Section 3.4.2 beginning on page 31 for PATA drives.

3.4.1 How to configure and connect Serial ATA (SATA) drives

3.4.1.1 How to configure the drive

Each drive on the SATA interface connects in a point-to-point configuration with the SATA host adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point relationships. If two drives are attached on one SATA host adapter, the host operating system views the two devices as if they were both “masters” on two separate ports. This m eans both drives behave as if they are Device 0 (master) devices.

SATA drives are designed for easy installation with no jumpers, terminators, or other settings. It is not necessary to set any jumpers on this drive for proper operation. The jumper block adjacent to the signal connector is for factory use only.

4.5 Set Features command

This command controls the implementation of various feat ures that the drive support s. When the drive receives this command, it sets BSY, checks the contents of the Features register, clears BSY and generates an interrupt. 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:

02 03

05 55 82 AA F1

Enable write cache (default).

Set transfer mode (based on value in Sector Count register).

Sector Count register values: 00

Enable advanced power management

Disable read look-ahead (read cache) feature.

Disable write cache.

Enable read look-ahead (read cache) feature (default).

Report full capacity available

Set PIO mode to default (PIO mode 2). Set PIO mode to default and disable IORDY (PIO mode 2). PIO mode 0 PIO mode 1 PIO mode 2 PIO mode 3 PIO mode 4 (default) Multiword DMA mode 0 Multiword DMA mode 1 Multiword DMA mode 2 Ultra DMA mode 0 Ultra DMA mode 1 Ultra DMA mode 2 Ultra DMA mode 3 Ultra DMA mode 4 Ultra DMA mode 5

Note. At power-on or after a hardware or software reset the default values of the features are as indicated

above.

4.6 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. commands and implementation, see the Draft ATA-5 Standard.

SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4

) that elimi-

nates unnecessary drive returns. The diagnostic software ships with all new drives and is also available at: http://seatools.sea

gate.com.

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.

If an appropriate code is not written to the Features Register, the command is aborted and 0x 04 (abort) is writ- ten to the Error register.
