2.6 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:

DiamondMax 20 PATA Product Manual, Rev. A 13

Page 22

• 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 av erage of at least 5,000 measurements of seeks betwee n random tracks, less overhead.

*Typical seek times (msec) Read Write

Track-to-track <0.8 <1.0 Average <11.0 <12.0 Average latency 4.16 4.16

*Measured in quiet mode 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.

2.8 Power specifications

The drive receives DC power (+5V or +12V) through a four-pin standard drive power connector.

2.8.1 Power consumption

Power requirements for the dr i ves ar e lis ted i n th e table s beg inn in g o n page 15. Typical power meas ur em ents are based on an av erage of driv es te sted, under nomin al co nditio ns, u sing +5.0V and + 12.0V input voltage a t 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 operatio n. Se rvo electr onics ar e active. S eek mode power repres ents the worstcase power consump tion, using only random se eks with read or write laten cy time. This mod e is not typic al and is provided for worst-case information.

• Read/write power and current

Read/write power is me asured with the he ads on track, b ased on a 16-sec tor 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 mea sure d using 40 percent random s eek s, 40 p er cent r ead /write mo de ( 1 wri te fo r e ach 10 reads) and 20 percent drive idle mode.

• Idle mode power

Idle mode power is measur ed wi th th e driv e up to s pee d, wi th ser vo ele ctron ics act ive and with the heads in a random track location.

• Standby mode

During Standby mode, the driv e accepts commands, but the drive is not spinning, and the ser vo and read/ write electronics are in power-down mode.

2.8.2 Conducted noise

Input noise ripple is mea su red at the ho st system power supply acr o ss an equ iv al ent 80 -ohm r es isti ve 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 expect ed to ope rate wi th a max imum of 1 0 0 mV peak -to-peak squa re-wav e injected noise at up to 10 MHz.

Note. Equival ent resistance is calcul ated by dividing the nomina l voltage by the typical RMS read/write

current.

2.8.3 Voltage tolerance

5V ± 5% 12V ± 10%

2.8.4 Power-management modes

The drive provides programmab le power mana gement to provide grea ter energy efficiency. In most systems, you can control power management through the system setup program. The drive features the following power-management modes :

Power mode Heads Spindle Buffer

Active Tracking Rotating Enabled Idle Tracking Rotating Enabled Standby Parked Stopped Enabled Sleep Parked Stopped Disabled

• Active mode

The drive is in Active mode during the read/write and seek operations.

• Idle mode

The buffer remains en abled, and the drive a ccepts a ll comm ands and re turns to Ac tive 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 dri ve can also enter Stand by mode automaticall y after the drive has be en 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 enab led, the heads are parked and the spi ndle 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 he ads are p arke d and the spind le is at rest. T he dr ive leav es Slee p mo de after it rece ives 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 perfo rms an Active function (read, wr ite or seek), the standby time r is reinitialized and begins counting down from its specified delay times to zero. If the standby timer reaches zero before any drive

18 DiamondMax 20 PATA Product Manual, Rev. A

2.14 Environmental protection

Seagate designs its prod ucts to meet environ mental protectio n requirem ents worldwide, in cluding regul ations restricting certain chemical substances.

2.14.1 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. Although amendments to the Euro-pean Union’s Restri ction of Hazardous Substances (Ro HS) Dire cti ve ha ve not bee n finalized, to the best of our knowledge the disc drives documented in this publication will comply with the final RoHS Directive require-ments.

A number of parts and materials in Seag ate products are procured from external suppl iers. We rely on the rep-resentations of our suppliers regarding the presence of RoHS substances in these parts and materials. Our supplier contracts r equire compliance with our chem ical substance restrictions, a nd our suppliers document their compliance with our requirements by providing material content declarations for all parts 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 ongoing 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 su bstances are not utiliz ed in our manufacturi ng operations, labora-tory analyti cal validatio n testing, and an internal auditing pr ocess to ens ure that all standar d operatin g procedures are complied with.

2.15 Corrosive environment

Seagate electronic driv e components pass accelerated corr osion testing equivalent to 10 ye ars exposure to light industrial envir onments containi ng sulfuro us gases, chlorine an d nitric oxide , classes G and H per ASTM B845. However, this accelerated testing cannot duplicate every potential application environment. Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as elec tronic drive componen t reliabi lity ca n be affected by th e installati on environm ent. The s ilver, 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 damaging. In addition, electr onic components should never be ex pose d to c ondensin g water on the surfac e of th e pri nted cir cuit bo ard a ssembly (PCBA ) or exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corr osive compoun ds should be m inimized or e liminated. Th e useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives.

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 dr ive may be ex posed to pote ntial handli ng and electros tatic discharge (ESD) hazards. Observe the following standard handling and static-discharge precautions:

Caution:

• Before handling the drive, put on a grounded wrist strap, or ground yourself frequently by touching the metal

chassis of a com puter that is plugge d into a grounded outl et. Wear a grounded wris t strap throughout th e 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 co ntain in for ma tio n nee ded to service the drive . O ther l abe ls ar e 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 d isc drives. Prop er precautions should be taken to en sure full functio nality and preven t 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 h ole.

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. Covering or sealing this hole voids the warranty.

3.3.3 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.

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.

Computer

Motherboard

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 detec ts the 80-conduc tor cable by sensing a capacitor at the host side thr ough the CBLID– signal. The result is repor ted 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 driv e in any o rientation u sing four screws in the s ide-mountin g hole s or four screws i n the bottom-mounting holes. See Figure 6 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.

• 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.
