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 m ax imu m d ata cy l inder an d b ac k to the first data
cylinder. The full-stro ke t ypic al v alue is dete rm in ed by ave ragi ng 10 0
full-stroke seeks in both directi on s.

Typical seek times (msec) Read Write

Track-to-track 1.2 2.0
Average 9.9 10.9
Full-stroke 22.0 24.0
Average latency: 5.55 msec — —

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-on to Ready (sec) 6.5 (typical)
Standby to Ready (sec) 6.5 (typical)

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 f or 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 di sc surface and does not execute a read or
write operation. S ervo e lectron ics are ac tive. Seek mode p ower 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, b ased on a
16-sector write followed by a 32-msec delay, then a 16-sec tor 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 pe rcent
drive inactive.

Idle mode power

•

Idle mode power is measured with the dri ve up to speed, with servo
electronics active and with the heads in a random track location.

Standby mode

•

During Standby mode , the drive acc epts comm ands, 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 i s mea su re d a t the host system power su ppl y ac ro ss
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, th e dri ve is ex pected to op er ate with a ma xi mum
of 100 mV peak-to-peak square-wave injected noise at up to 10 MHz.

Note.

Equivalent resis tance is calcu lated by di viding the nomina l volt­age 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 great­er energy efficiency . In m ost sys tems, you can contr ol po wer mana ge­ment through the system setup program. The drive features the following
power-management modes:

Power Modes 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 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 hos t has set the sta ndby ti mer, the drive
can also enter Standby mo de automatical ly after the driv e has been
inactive for a specifia ble length of time. The standby ti mer delay is

U Series Family Product Manual, Rev. B 11

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 m ode after receiv ing a Slee p command from
the host. In S leep mode, the drive buffer is disabl ed, the heads are
parked and the spindle is at res t. The drive l eaves Sleep mode a fter
it receives a Hard Reset or Soft Reset from the host. After receiving a
reset, the drive exits Sleep mo de 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 reinitia lized and begins counting down from its
specified delay times to zero. If the standby timer reaches zero before
any drive activity is require d, the dr ive make s a tran siti on to Stan dby
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

drive may experience without incurring physical damage or degradation
in performance when subsequently put into operation.

5–21 Hz 0.2-inch displacement (peak to peak)
22–350 Hz 5.0 Gs acceleration (zero to peak)
351–500 Hz 1.0 Gs acceleration (zero to peak)

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)

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 cable s, software
loading and label/barc ode scanning with out removing the drive from
the SeaShell. This minimizes handling damage. Keep the drive in the
SeaShell package until you are ready to install it.

The drive is enclosed in a black, flexible cover called a SeaShield

•

not remove this per manent cover— it protects t he drive from el ectro­static discharge (ESD) and minor impact damage. The soft SeaShield
cover also incl udes instal lation inst ructions a nd jumper s ettings. Re­moving the SeaShield voids the warranty.

Before handling the drive, put on a grounde d wrist strap, or ground

•

yourself frequentl y by touching the metal chas sis of a com puter 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

•

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, antista tic su rfac e until you moun t

•

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.

2.2.2 Cable-select option

Computers that use cable-select determine the master and slave drives
by selecting or dese lecting p in 28, CSEL, on the interfac e bus. Mas ter
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” at startup if their BIOS detects a hard
drive that has values greater than either 4,092 (2.1 Gbytes) cylinders or
approximately 32 Gbyt es. To elim inate thi s problem , the drive inclu des
a capacity-limiting jumper that sets the drive’s default translation geometry
to 4,092 cylinders fo r mod el ST 3 204 10A an d l imits th e d riv e’s cap ac ity
to 2.1 Gbytes. The ST3 80020A, ST360020A and the ST340810A are
limited to 32 Gbyte s when the alternate capacity jumper i s used. To
realize the full capac ity of the drive, you can use thir d-party software
such as DiscWizard or Disk Manager.

If the alternate capa city j umper is used on dr ives under 32 Gbytes, the
drive’s true LBAs are found in ID words 60 and 61. On larg er-capacity
drives, the alternate capacity jumper “freezes” words 60 and 61 at a value
below the problem barrier point. The ATA Set Max command is used to
“unfreeze” and fill the real values in words 60 and 61 after the command
is issued.

Windows 98 or newer versions are needed to support drives with
capacities greater than 32 Gbytes.

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 cabl e uses even -numbered c onductors 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-cond uctor 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).

2.1 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 for drive mounting dimensions. Follow these important mounting
precautions when mounting the drive:

•

Allow a minimum clearanc e 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.

3.1.3 Set Features command

This command contr ol s the im pl eme ntation of various featu re s 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 interrupt. If the value in the register does not represent a feature that
the drive supports, th e command is aborted . Power-on d efault has the
read look-ahead and write caching features enabl ed. The acceptable
values for the Features register are defined as follows:

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 deg radation over time. If self-monitorin g determines
that a failure is likely, S.M.A.R.T. makes a status report available to the
host. Not all failur es are predi ctable. S.M.A.R. T. predict ability is lim ited to
the attributes the drive can monitor. For more information on S.M.A.R.T.
commands and implementation, see the

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 pack age th at supports S.M.A.R.T. to enabl e
this feature. The table below shows the S.M.A.R.T. command codes that
the drive uses.
