3.2 UNPACKING INSTRUCTIONS

CAUTION: The maximum limits for physical shock can be exceeded if the

drive is not handled properly. Special care should be
taken not to bump or drop the drive. It is highly recommended
that Maxtor Quickview 300 drives are not stacked or placed on
any hard surface after they are unpacked. Such handling could
cause media damage.

1. Open the shipping container and remove the packing assembly
that contains the drive.

2. Remove the drive from the packing assembly.

CAUTION: During shipment and handling, the antistatic electrostatic dis-

charge (ESD) bag prevents electronic component
damage due to electrostatic discharge. To avoid accidental dam­age to the drive, do not use a sharp instrument to open the ESD
bag and do not touch PCB components. Save the packing mate­rials for possible future use.

3. When you are ready to install the drive, remove it from the ESD
bag.

3.3 HARDWARE OPTIONS

3.3.1 PATA Interface Connector

The configuration of a Quickview 300 PATA hard disk drive depends on
the host system in which it is to be installed. This section describes the
hardware options that you must take into account prior to installation.

Figure 3-3 Jumper Locations on the PATA Interface Connector

3-4 Quickview 300 80/100/120/160/200/250/300GB PATA

Installation

The configuration of the following three jumpers controls the drive’s five
modes of operation:

• CS – Cable Select

• DS – Drive Select

• CLJ– Cylinder Limitation Jumper

• POSB - Power on standby (Remote Command)

The AT PCB has two jumper locations provided to configure the drive in
a system. The default configuration for the drive as shipped from the
factory is with a jumper across the CS location, and open positions in
the DS and CLJ positions.

Table 3-1 defines the operation of the master/slave jumpers and their
function relative to pin 28 on the interface. 1 indicates that the specified
jumper is installed; 0 indicates that the jumper is not installed.

Table 3-1 AT Jumper Options

CS DS PIN 28 PIN 42 PIN 44 DESCRIPTION

become ready on a few seconds after power if
jumpers on pin 42 and pin 44 are set.
(Feature = 7,CMD = 0xEF Hex to spin up
drive)

Note: In Table 3-1, a 0 indicates that the jumper is removed,

a 1 indicates that the jumper is installed, and an X indi­cates that the jumper setting does not matter.

3.3.1.1 Cable Select (CS) Jumper

When a Quickview 300 PATA hard disk drive and another PATA hard
disk drive are daisy-chained together, they can be configured as Master
or Slave either by the CS or DS jumpers. To configure the drive as a

Quickview 300 80/100/120/160/200/250/300GB PATA 3-5

Installation

Master or Slave with the CS feature, the CS jumper is installed (1). The
drive's position on the 80 pin conductor Ultra ATA data cable then
determines whether the drive is a Master (Device 0) or a Slave (Device

1). If the drive is connected to the end of the Ultra (cable Select) data
cable the drive is a Master. If the drive is connected to the middle
connection it is set as a Slave.

Once you install the CS jumper, the drive is configured as a Master or
Slave by the state of the Cable Select signal: pin 28 of the PATA bus
connector. Please note that pin 28 is a vendor-specific pin that Maxtor
is using for a specific purpose. More than one function is allocated to
CS, according to the PATA CAM specification (see reference to this
specification in Chapter 1). If pin 28 is a 0 (grounded), the drive is
configured as a Master. If it is a 1 (high), the drive is configured as a
Slave. In order to configure two drives in a Master/Slave relationship
using the CS jumper, you need to use a cable that provides the proper
signal level at pin 28 of the PATA bus connector. This allows two drives
to operate in a Master/Slave relationship according to the drive cable
placement.

The Quickview 300 PATA hard disk drives are shipped from the factory
as a Master (Device 0 - CS jumper installed). To configure a drive as a
Slave (Device 1- DS scheme), the CS jumper must be removed. In this
configuration, the spare jumper removed from the CS position may be
stored on the PK jumper pins.

3.3.1.2 Drive Select (DS) Jumper

You can also daisy-chain two drives on the PATA bus interface by using
their Drive Select (DS) jumpers. To use the DS feature, the CS jumper
must not be installed.

To configure a drive as the Master (Device 0), a jumper must be installed
on the DS pins.

Note: The order in which drives are connected in a daisy chain

has no significance.

3.3.1.3 Master Jumper Configuration

In combination with the current DS or CS jumper settings, the Slave
Present (SP) jumper can be implemented if necessary as follows:

The CS position doubles as the Slave present on this drive.

• When the drive is configured as a Master (DS jumper installed

or CS jumper installed, and the Cable Select signal is set to
(0), adding an additional jumper (both jumpers DS and CS now
installed) will indicate to the drive that a Slave drive is
present. This Master with Slave Present jumper configuration
should be installed on the Master drive only if the Slave drive
does not use the Drive Active/Slave Present (DASP–) signal
to indicate its presence.

3.3.1.4 Power On Standby

Upon power on, the drive will not spin up and will be in a power saving mode,
irrespective of the other jumper settings.

To spin up the drive, issue a Set Feature (OxEF) command with a sub-code 7.

In the power saving mode, the drive will reject all other commands.

Jumpers Setup

Drive will spin up as normal drive and become ready in a few seconds after power
up if the jumpers on pin 42 and pin 44 were not set.

3.3.1.5 Cylinder Limitation Jumper (CLJ)

For user capacities below 66,055,248 sectors (32GB), inserting the CLJ
jumper limits the Number of Cylinders field 1 to a value of 16,383, as
reported in IDENTIFY DEVICE data word. This allows software drivers
to determine that the actual capacity is larger than indicated by the
maximum CHS, requiring LBA addressing to use the full capacity.

3.3.2 PATA BUS ADAPTER

There are two ways you can configure a system to allow the Maxtor
hard disk drives to communicate over the PATA bus of an IBM or IBM­compatible PC:

1. Connect the drive to a 40-pin PATA bus connector (if available) on
the motherboard of the PC.

2. Install an IDE-compatible adapter board in the PC, and connect
the drive to the adapter board.

3.3.2.1 40-Pin PATA Bus Connector

Most motherboards have a built-in 40-pin PATA bus connector that is
compatible with the 40-pin PATA interface of the Quickview 300 80/
100/120/160/200/250/300GB PATA hard disk drives. If the
motherboard has an PATA connector, simply connect a 80-pin
conductor ribbon cable between the drive and the motherboard.

You should also refer to the motherboard instruction manual to ensure
signal compatibility.

Installation

3.3.2.2 Adapter Board

If your PC motherboard does not contain a built-in 40-pin PATA bus
interface connector, you must install an PATA bus adapter board and
connecting cable to allow the drive to interface with the motherboard.

Please carefully read the instruction manual that comes with your
adapter board, as well as Chapter 5 of this manual to ensure signal
compatibility between the adapter board and the drive. Also, make sure
that the adapter board jumper settings are appropriate.

3.4 COMBINATION CONNECTOR (J1)

J1 is a three-in-one combination connector. The drive’s DC power can
be applied to section A. The PATA bus interface (40-pin) uses section
C. The connector is mounted on the back edge of the printed-circuit
board (PCB), as shown in Figure 3-5.

3.4.3 PATA Bus Interface Connector (J1, Section C)

On the Quickview 300 80/100/120/160/200/250/300GB PATA hard
disk drives, the PATA bus interface cable connector (J1, section C) is a
40-pin Universal Header, as shown in Figure 3-5.

To prevent the possibility of incorrect installation, the connector has
been keyed by removing Pin 20. This ensures that a connector cannot
be installed upside down.

See Chapter 5, “PATA Bus Interface and PATA Commands,” for more
detailed information about the required signals. Refer to Table 5-1 for
the pin assignments of the PATA bus connector (J1, section C).

3.5.2 Clearance

Clearance from the drive to any other surface (except mounting
surfaces) must be a minimum of 1.25 mm (0.05 inches).

3.5.3 Ventilation

The Maxtor Quickview 300 80/100/120/160/200/250/300GB PATA
hard disk drives operate without a cooling fan, provided the base casting
temperature as measured where the motor is attached to the base
casting does not exceed 158

°F (70°C).

3.5.4 For Systems With A Motherboard PATA Adapter

You can install the Maxtor Quickview 300 80/100/120/160/200/250/
300GB PATA hard disk drives in an AT-compatible system that contains
a 40-pin PATA bus connector on the motherboard.

To connect the drive to the motherboard, use a 80 conductor ribbon
cable 18 inches in length or shorter. Ensure that pin 1 of the drive is
connected to pin 1 of the motherboard connector.

3.6 For Systems With An PATA Adapter Board

To install the 80/100/120/160/200/250/300GB PATA hard disk drive
in an AT-compatible system without a 40-pin PATA bus connector on
its motherboard, you need a third-party IDE-compatible adapter board.

3.6.1 Adapter Board Installation

Carefully read the manual that accompanies your adapter board before
installing it. Make sure that all the jumpers are set properly and that
there are no address or signal conflicts. You must also investigate to see
if your AT-compatible system contains a combination floppy and hard
disk controller board. If it does, you must disable the hard disk drive
controller functions on that controller board before proceeding.

Once you have disabled the hard disk drive controller functions on the
floppy/hard drive controller, install the adapter board. Again, make sure
that you have set all jumper straps on the adapter board to avoid
addressing and signal conflicts.

Note: For Sections 3.5.4 thru 3.6, power should be turned off

on the host system before installing the drive.

3-14 Quickview 300 80/100/120/160/200/250/300GB PATA

3.6.1.1 Connecting the Adapter Board and the Drive

Use a 40-pin cable to connect the drive to the board.

See figure 3-8 to connect the drive to the board:

1. Insert the 80-pin conductor cable into the mating connector of the adapter
board. Make sure that pin 1 of the connector matches with pin 1 on the
cable.

2. Insert the other end of the cable into the header on the drive.
When inserting this end of the cable, make sure that pin 1 of the
cable connects to pin 1 of the drive connector.

ATA BUS INTERFACE AND ATA COMMANDS

This chapter describes the interface between the Quickview 300 hard
disk drives and the PATA bus. The commands that are issued from the
host to control the drive are listed, as well as the electrical and
mechanical characteristics of the interface.

5.1 INTRODUCTION

Maxtor Quickview 300 hard disk drives use the standard ATA/ATAPI
interface. Support of various options in the standard are explained in
the following sections.

5.2 MECHANICAL INTERFACE

5.2.1 Signal Cable and Connector

The Quickview 300 hard disk drive contains a 40-pin unitized
connector for both signal and power connections as well as
configuration jumpers. The dimensions and specifications of the
unitized connector comply with Annex. A in the ATA/ATAPI standard.

The Quickview 300 drives require the use of an 80 conductor cable
(ATA/ATAPI-6, Annex. A, Figure A.4 and description) to support the
drive’s Ultra DMA capability.

5.3 ELECTRICAL INTERFACE

5.3.1 PATA Bus Interface

5.3.1.1 Electrical Characteristics

Signals on the PATA interface are assigned to connector pins according
to Annex. A in the ATA/ATAPI-6 standard for the 80 conductor cable
assembly. The signaling protocol complies with clause 9 and signal timing
complies with clause 10 of the standard.

The Quickview 300 hard disk drives support all Ultra DMA Data Transfer
modes (0 - 5) defined in the ATA/ATAPI-6 standard and are ATA/ATAPI­7 compliant. In addition, these drives support Mode 6, and can send and
receive data at the full 133MB/s transfer rate.

Quickview 300 80/100/120/160/200/250/300GB PATA 5-1

ATA Bus Interface and ATA Commands

Hosts may assert the RESET- signal for longer than the minimum. When
power is applied with RESET- asserted, the Quickview 300 disk media
will not begin to spin up until RESET- is negated. This may reduce
maximum current consumption for the overall system.

5.4 REGISTER ADDRESS DECODING

The Quickview 300 hard disk drives allow their host systems to address
the full set of command and control registers as specified in clause 7 of
the ATA/ATAPI-6 standard.

5.5 COMMAND INTERFACE

5.5.1 General Feature Set

The µProcessor, Disk Controller, and PATA Interface electronics are
contained in a proprietary ASIC developed by Maxtor.

Identify Drive Command

This command allows the host to receive parameter information from the
drive.

When the command is received, the drive:

1.Sets BSY

2. Stores the required parameter information in the sector buffer

3. Sets the DRQ bit

4. Generates an interrupt

The host may then read the information out of the sector buffer.
Parameter words in the buffer are shown in Table 5-2.

Note: All reserved bits or words should be zeroes.

BREAKING THE 137 GIGABYTE STORAGE

This appendix provides information about the 137GB storage barrier. It
discusses the history, cause and the solution to overcome this barrier.

A.1 Breaking the 137 Gigabyte Storage Barrier

Capacity barriers have been a fact of the personal computer world since
its beginnings in the early 1980’s. At least 10 different capacity barriers
have occurred in the storage industry over the last 15 years. The most
notable barriers seen previously have been at 528 megabytes and then at

8.4 gigabytes.

The ANSI NCITS T13 Technical Committee (also known as the ANSI ATA
committee) has broken this barrier by incorporating a proposal from
Maxtor into the ATA/ATAPI-6 draft standard that defines a method for
48-bit addressing on a single drive, giving more than 144 petabytes
(144,000 gigabytes) of storage.

Appendix A

BARRIER

In addition, the proposal from Maxtor that was incorporated into ATA/
ATAPI-6 defines a method for extending the maximum amount of data
that can be transferred per command for ATA devices from 256 sectors
(about 131 kilobytes) to 65,536 sectors (about 33 megabytes). This new
method is particularly useful for applications that use extremely large
files, such as those for A/V or multimedia.

The following sections will describe issues surrounding the 137-gigabyte
barrier and the solution for breaking it.

A.1.1 History

Many of the “barriers” in the past resulted from BIOS and operating
system issues caused by failure to anticipate the remarkable increases in
device storage capacity by the people who designed hard disk structures,
access routines, and operating systems many years ago. They thought,
“Who will ever have xxx much storage?” In some cases, the barriers were
caused by hardware or software bugs not found until hard disks had
grown in size beyond a certain point where the bugs would occur.

Past barriers often frustrated people trying to add a new hard disk to an
older system when they discovered that not all of the designed capacity

Quickview 300 80/100/120/160/200/250/300GB PATA A-1

Breaking the 137GB Storage Barrier

t

of the hard disk was accessible. This inability to access the entire drive is
referred to as a “capacity barrier” and it has been seen and overcome
many times in the computer and disk drive industry.

The 137-gigabyte barrier is the result of the original design specification
for the ATA interface that provided only 28 bits of address for data. This
specification means a hard disk can have a maximum of 268,435,456
sectors of 512 bytes of data which puts the ATA interface maximum at

137.4 gigabytes.

A.1.2 Solving the 137 Gigabyte Capacity Barrier

As described earlier, the issue causing the 137-gigabyte barrier is the 28­bit addressing method of the original ATA specification. A change to
expand this method was required to provide more address bits for the
interface, allowing significant growth for many years to come. A critical
issue in expanding the addressing capability was maintaining
compatibility with the existing installed base of products.

The new ATA standard, ATA/ATAPI-6, resolves this issue by increasing
the maximum number of bits used for addressing from 28 to 48. This
solution increases the maximum capacity of an ATA device to 144
petabytes while maintaining compatibility with current ATA products.

A.1.3 How is the Extension Implemented?

The 48-bit Address feature set provides a method to address devices with
capacities up to approximately 144 petabytes by increasing the number
of bits used to specify logical block addresses (LBAs) from 28 to 48. The
feature set also provides a method to increase the number of sectors that
can be transferred by a single command from 256 to 65,536 by
increasing the number of bits specifying sector count to 16 bits.

Breaking the 137GB Storage Barrier

New commands specific to this feature set have been defined so that
devices can implement the new feature set in addition to previously
defined commands. Devices implementing the 48-bit Address feature set
commands will also implement commands that use 28-bit addressing in
order to maintain interoperability with older system components. In
addition, 8-bit and 48-bit commands may be intermixed.

The 48-bit Address feature set operates in LBA addressing only. Support
of the 48-bit Address feature set is indicated in the IDENTIFY DEVICE
response data. In a device implementing the 48-bit Address feature set,
the registers used for addressing are, in fact, a two-byte deep FIFO. Each
time one of these registers is written, the new content written is placed
into the “most recently written” location and the previous content of the
register is moved to “previous content” location. A host may read the
“previous content” of the registers by first setting a bit in the Device
Control register to 1 and then reading the desired register.

A.1.4 What Do the Drives Need to Meet the Spec?

The challenge to drive manufacturers is to develop and implement new
interface chips on drives that can accept and decode the new 48-bit
addressing scheme. Many functions of decoding the commands sent to
and from the drive are automated in the silicon of the drive interface
ASIC, and this is where drive manufacturers must update their designs.
Maxtor is the leader in development efforts and is the first to deliver a
product with the capacity and drive technology to deliver greater than
137 gigabytes of capacity.

Breaking the 137GB Storage Barrier

A.1.5 What Else is Involved?

Effort is required from OS vendors to increase storage device addressing
up to 48 bits or more. This increase will be a significant challenge for
many OS vendors that have 32-bit code models. Adapting to 48-bit
commands will be easy, but most vendors will stop filling data at the 32­bit boundary and pad the upper 16 bits with zeros, leaving that space
empty.

The BIOS companies will also have to perform some work to recognize
the increased capacity of the devices attached to the bus and allow the
extended 48-bit commands to pass on to the devices. Boot partitions will
also be an issue for the capacity of the drive if the BIOS does not
recognize the 48-bit addressing scheme at or before the system boots the
OS from the hard drive.

Independent software driver efforts for legacy operating systems
(Windows NT 4, Windows 98, and so on) will need to be implemented to
allow higher-capacity devices to work on installed systems and recognize
the maximum available capacity of the drive over the 137-gigabyte limit.

A.1.6 What is the Next Barrier?

While it is true that the ATA/ATAPI-6 standard defines a method to
provide a total capacity for a device of 144 petabytes, the next limit will
be imposed not by the ATA devices but by many of the popular operating
systems in use today. This limit will be at 2.2 terabytes (2,200
gigabytes). This barrier exists because many of today’s operating
systems are based on 32-bit addressing. These operating systems include
many flavors of Linux, Mac OS 9.x, and Windows 95, 98, ME, NT 4,

GLOSSARY

A

ACCESS – (v) Read, write, or update
information on some storage medium, such as
a disk. (n) One of these operations.

ACCESS TIME – The interval between the
time a request for data is made by the system
and the time the data is available from the
drive. Access time includes the actual seek
time, rotational latency, and command
processing overhead time. See also seek,
rotational latency, and overhead.

ACTUATOR – Also known as the positioner.
The internal mechanism that moves the
read/write head to the proper track. The
Maxtor actuator consists of a rotary voice coil
and the head mounting arms. One end of each
head mounting arm attaches to the rotor with
the read/write heads attached at the opposite
end of each arm. As current is applied to the
rotor, it rotates, positioning the heads over the
desired cylinder on the media.

ALLOCATION – The process of assigning
particular areas of the disk to particular files.
See also allocation unit.

B

BACKUP – A copy of a file, directory, or
volume on a separate storage device from the
original, for the purpose of retrieval in case the
original is accidentally erased, damaged, or
destroyed.

BAD BLOCK – A block (usually the size of
a sector) that cannot reliably hold data because
of a media flaw or damaged format markings.

BAD TRACK TABLE – A label affixed to
the casing of a hard disk drive that tells which
tracks are flawed and cannot hold data. The
listing is typed into the low-level formatting
program when the drive is being installed.
Because Maxtor disk drive’s
defect-management scheme handles all such
flaws automatically, there is no need to
concern yourself with bad track tables.

BIT – Abbreviation for binary digit. A binary
digit may have one of two values—1 or 0.
This contrasts with a decimal digit, which
may have a value from 0 to 9. A bit is one of
the logic 1or logic 0 binary settings that make
up a byte of data. See also byte.

ALLOCATION UNIT – An allocation
unit, also known as a cluster, is a group of
sectors on the disk that can be reserved for the
use of a particular file.

AVERAGE SEEK TIME – The average
time it takes for the read/write head to move
to a specific location. To compute the average
seek time, you divide the time it takes to
complete a large number of random seeks all
over the disk by the number of seeks
performed.

Quickview 300 80/100/120/160/200/250/300GB PATA G-1

BLOCK – A sector or group of sectors. By

default, a block of data consists of 512 bytes.

Glossary

BPI – Abbreviation for bits per inch. A
measure of how densely information is packed
on a storage medium. Flux changes per inch is
also a term commonly used in describing
storage density on a magnetic surface.

BUFFER – An area of RAM reserved for
temporary storage of data that is waiting to be
sent to a device that is not yet ready to receive
it. The data is usually on its way to or from the
disk drive or some other peripheral device.

BUS – The part of a chip, circuit board, or
interface designed to send and receive data.

BYTE – The basic unit of computer
memory, large enough to hold one character
of alphanumeric data. Comprised of eight bits.
See also bit.

C

CACHE – Random-access memory used as a
buffer between the CPU and a hard disk.
Information more likely to b e r ea d o r c ha ng ed
is placed in the cache, where it can be accessed
more quickly to speed up general data flow.

CAPACITY – The amount of information
that can be stored on a disk drive. The data is
stored in bytes, and capacity is usually
expressed in megabytes.

CDB – Command Descriptor Block. The
SCSI structure used to communicate requests
from an initiator (system) to a target (drive).

CLEAN ROOM – An environmentally
controlled dust-free assembly or repair facility
in which hard disk drives are assembled or can
be opened for internal servicing.

CLUSTER – A group of sectors on a disk
drive that is addressed as one logical unit by
the operating system.

CONTROLLER – Short form of disk
controller. The chip or complete circuit that

translates computer data and commands into a
form suitable for use by the disk drive.

CONTROLLER CARD – An adapter
holding the control electronics for one or
more hard disks, usually installed in a slot in
the computer.

CPU – Acronym for Central Processing Unit.
The microprocessor chip that performs the
bulk of data processing in a computer.

CRC – Acronym for Cyclic Redundancy Check.
An error detection code that is recorded
within each sector and is used to see whether
parts of a string of data are missing or
erroneous.

CYLINDER – On a disk drive that has more
than one recording surface and heads that
move to various tracks, the group of all tracks
located at a given head position. The number
of cylinders times the number of heads equals
the number of tracks per drive.

D

DATA SEPARATOR – On a disk drive
that stores data and timing information in an
encoded form, the circuit that extracts the
data from the combined data and clock signal.

DEDICATED SERVO – A surface separate
from the surface used for data that contains
only disk timing and positioning information
and contains no data.

DEFECT MANAGEMENT – A method
that is implemented to ensure long term data
integrity. Defect management eliminates the
need for user defect maps. This is
accomplished by scanning the disk drives at
the factory for defective sectors. Defective
sectors are deallocated prior to shipment. In
addition, during regular use, the drive
continues to scan and compensate for any new
defective sectors on the disk.

DISK – In general, any circular-shaped
data-storage medium that stores data on the
flat surface of the platter. The most common
type of disk is the magnetic disk, which stores
data as magnetic patterns in a metal or
metal-oxide coating. Magnetic disks come in
two forms: floppy and hard. Optical recording
is a newer disk technology that gives higher
capacity storage but at slower access times.

Glossary

DISK CONTROLLER – A plug-in board,
or embedded circuitry on the drive, that
passes information to and from the disk. The
Maxtor disk drives all have controllers
embedded on the drive printed-circuit board.

DISKWARE – The program instructions
and data stored on the disk for use by a
processor.

DMA – Acronym for direct memory access. A
process by which data moves directly between
a disk drive (or other device) and system
memory without passing through the CPU,
thus allowing the system to continue
processing other tasks while the new data is
being retrieved.

DRIVE – Short form of disk drive.

DRIVE GEOMETRY – The functional

dimensions of a drive in terms of the number
of heads, cylinders, and sectors per track. See
also logical format.

E

ECC – Acronym for error correction code. The
recording of extra verifying information
encoded along with the disk data. The
controller uses the extra information to check
for data errors, and corrects the errors when
possible.

EMBEDDED SERVO – A timing or
location signal placed on the disk’s surface on
the tracks that also store data. These signals
allow the actuator to fine-tune the position of
the read/write heads.

ENCODING – The protocol by which
particular data patterns are changed prior to
being written on the disk surface as a pattern
of On and Off or 1 and 0 signals.

EXTERNAL DRIVE – A drive mounted in
an enclosure separate from the PC or
computer system enclosure, with its own
power supply and fan, and connected to the
system by a cable.

F

FAT – Acronym for file allocation table. A data
table stored on the outer edge of a disk that
tells the operating system which sectors are
allocated to each file and in what order.

FCI – Acronym for flux changes per inch. See
also BPI.

FILE SERVER – A computer that provides
network stations with controlled access to
shareable resources. The network operating
system is loaded on the file server, and most
shareable devices (disk subsystems, printers)
are attached to it. The file server controls
system security and monitors
station-to-station communications. A
dedicated file server can be used only as a file
server while it is on the network. A non
dedicated file server can be used
simultaneously as a file server and a
workstation.

FLUX DENSITY – The number of
magnetic field patterns that can be stored in a
given length of disk surface. The number is
usually stated as flux changes per inch (FCI),
with typical values in the thousands.

FLYING HEIGHT – The distance between
the read/write head and the disk surface
caused by a cushion of air that keeps the head
from contacting the media. Smaller flying
heights permit more dense storage of data, but
require more precise mechanical designs.

FORMAT – To write onto the disk surface a
magnetic track pattern that specifies the
locations of the tracks and sectors. This
information must exist on a disk before it can
store any user data. Formatting erases any
previously stored data.

FORMATTED CAPACITY – The
amount of room left to store data on the disk
after the required space has been used to write
sector headers, boundary definitions, and
timing information generated by a format
operation. All Maxtor drive capacities are
expressed in formatted capacity.

FORM FACTOR – The physical outer
dimensions of a device as defined by industry
standard. For example, most Maxtor disk
drives use a 3 1/2-inch form factor.

AT and compatible computers so that the
drive easily slides into place.

H

drive that occupies half the vertical space of
the original full size 5 1/4-inch drive. 1.625
inches high.

HARD DISK – A type of storage medium
tha t ret ai ns da ta as ma g net ic pa tt er ns on a r ig id
disk, usually made of an iron oxide or alloy
over a magnesium or aluminum platter.
Because hard disks spin more rapidly than
floppy disks, and the head flies closer to the
disk, hard disks can transfer data faster and
store more in the same volume.

HARD ERROR – A repeatable error in disk
data that persists when the disk is reread,
usually caused by defects in the media surface.

HEAD – The tiny electromagnetic coil and
metal pole piece used to create and read back
the magnetic patterns (write and read
information) on the media.

HIGH-CAPACITY DRIVE – By industry
conventions typically a drive of 1 gigabytes or
more.

I

INITIALIZE – See low level formatting.

INITIATOR – A SCSI device that requests

another SCSI device to perform an operation.
A common example of this is a system
requesting data from a drive. The system is the
initiator and the drive is the target.

INTERFACE – A hardware or software
protocol, contained in the electronics of the
disk controller and disk drive, that manages
the exchange of data between the drive and
computer.

INTERLEAVE – The arrangement of
sectors on a track. A 1:1 interleave arranges
the sectors so that the next sector arrives at the
read/write heads just as the computer is ready
to access it. See also interleave factor.

INTERLEAVE FACTOR – The number
of sectors that pass beneath the read/write
heads before the next numbered sector
arrives. When the interleave factor is 3:1, a
sector is read, two pass by, and then the next
is read. It would take three revolutions of the
disk to access a full track of data. Maxtor
drives have an interleave of 1:1, so a full track
of data can be accessed within one revolution
of the disk, thus offering the highest data
throughput possible.

INTERNAL DRIVE – A drive mounted
inside one of a computer’s drive bays (or a
hard disk on a card, which is installed in one
of the computer’s slots).

J

HIGH-LEVEL FORMATTING –
Formatting performed by the operating
system’s format program. Among other
things, the formatting program creates the
root directory and file allocation tables. See
also low-level formatting.

HOME – Reference position track for
re-calibration of the actuator, usually the
outer track (track 0).

HOST ADAPTER – A plug-in board that
forms the interface between a particular type
of computer system bus and the disk drive.

G-4 Quickview 300 80/100/120/160/200/250/300GB PATA

JUMPER – A tiny box that slips over two
pins that protrude from a circuit board. When
in place, the jumper connects the pins
electrically. Some board manufacturers use
Dual In-Line Package (DIP) switches instead
of jumpers.

Glossary

K

KILOBYTE (Kb) – A unit of measure
consisting of 1,024 (2

10

) bytes.

L

LANDING ZONE – A position inside the
disk’s inner cylinder in a non data area
reserved as a place to rest the heads during the
time that power is off. Using this area prevents
the heads from touching the surface in data
areas upon power down, adding to the data
integrity and reliability of the disk drive.

LATENCY – The period of time during
which the read/write heads are waiting for the
data to rotate into position so that it can be
accessed. Based on a disk rotation speed of
3,662 rpm, the maximum latency time is 16.4
milliseconds, and the average latency time is

8.2 milliseconds.

LOGICAL FORMAT – The logical drive
geometry that appears to an AT system BIOS
as defined by the drive tables and stored in
CMOS. With an installation program like
Disk Manager, the drive can be redefined to
any logical parameters necessary to adapt to
the system drive tables.

LOOK AHEAD – The technique of
buffering data into cache RAM by reading
subsequent blocks in advance to anticipate the
next request for data. The look ahead
technique speeds up disk access of sequential
blocks of data.

LOW-LEVEL FORMATTING –
Formatting that creates the sectors on the
platter surfaces so the operating system can
access the required areas for generating the file
structure. Maxtor drives are shipped with the
low-level formatting already done.

LOW PROFILE – Describes drives built to
the 3 1/2-inch form factor, which are only 1
inch high.

M

MB – See megabyte.

MEDIA – The magnetic film that is

deposited or coated on an aluminum substrate
which is very flat and in the shape of a disk.
The media is overcoated with a lubricant to
prevent damage to the heads or media during
head take off and landing. The media is where
the data is stored inside the disk in the form of
magnetic flux or polarity changes.

MEGABYTE (MB) – A unit of
measurement equal to 1,024 kilobytes, or
1,048,576 bytes except when referring to disk
storage capacity.

MEGAHERTZ – A measurement of
frequency in millions of cycles per second.

MHz – See megahertz.

MICROPROCESSOR – The integrated

circuit chip that performs the bulk of data
processing and controls the operation of all of
the parts of the system. A disk drive also
contains a microprocessor to handle all of the

the embedded controller.

MICROSECOND (µs) – One millionth of
a second (.000001 sec.).

MILLISECOND (ms) – One thousandth of
a second (.001 sec.).

MTTF – MTTF is a basic measure of
reliability for non-repairable systems. It is the
mean time expected until the first failure of a
piece of equipment. MTTF is a statistical
value and is meant to be the mean over a long
period of time and large number of units. For
constant failure rate systems, MTTF is the
inverse of the failure rate. If failure rate is in
failures/million hours, MTTF = 1,000,000 /
Failure Rate for components with
exponential distributions.

MTTR – Mean Time To Repair. The
average time it takes to repair a drive that has
failed for some reason. This only takes into
consideration the changing of the major
sub-assemblies such as circuit board or sealed
housing. Component level repair is not
included in this number as this type of repair
is not performed in the field.

O

OVERHEAD – The processing time of a
command by the controller, host adapter or
drive prior to any actual disk accesses taking
place.

OVERWRITE – To write data on top of
existing data, erasing it.

other metal oxides, and the term has become
a general one for the magnetic coating on tape
or disk.

P

PLATTER – An disk made of metal (or
other rigid material) that is mounted inside a
fixed disk drive. Most drives use more than
one platter mounted on a single spindle (shaft)
to provide more data storage surfaces in a
small package. The platter is coated with a
magnetic material that is used to store data as
transitions of magnetic polarity.

POH – Acronym for power on hours. The unit

with a hard metal alloy instead of an
iron-oxide compound. Plated disks can store
greater amounts of data in the same area as a
coated disk.

G-6 Quickview 300 80/100/120/160/200/250/300GB PATA

RAM DISK – A “phantom disk drive” for
which a section of system memory (RAM) is
set aside to hold data, just as if it were a
number of disk sectors. The access to this data
is extremely fast but is lost when the system is
reset or turned off.

READ AFTER WRITE – A mode of
operation that has the computer read back
each sector on the disk, checking that the data
read back is the same as recorded. This slows
disk operations, but raises reliability.

READ VERIFY – A disk mode where the
disk reads in data to the controller, but the
controller only checks for errors and does not
pass the data on to the system.

READ/WRITE HEAD – The tiny
electromagnetic coil and metal pole piece
used to create and read back the magnetic
patterns (write or read information) on the
disk. Each side of each platter has its own
read/write head.

Glossary

REMOVABLE DISK – Generally said of
disk drives where the disk itself is meant to be
removed, and in particular of hard disks using
disks mounted in cartridges. Their advantage
is that multiple disks can be used to increase
the amount of stored material, and that once
removed, the disk can be stored away to
prevent unauthorized use.

RLL – Run Length Limited. A method used
on some hard disks to encode data into
magnetic pulses. RLL requires more
processing, but stores almost 50% more data
per disk than the MFM method.

Usually in the form of an ROM in the
controller that contains programs that can be
accessed and read but not modified by the
system.

ROTARY ACTUATOR – The rotary
actuator replaces the stepper motor used in the
past by many hard disk manufacturers. The
rotary actuator is perfectly balanced and
rotates around a single pivot point. It allows
closed-loop feedback positioning of the heads,
which is more accurate than stepper motors.

ROTATIONAL LATENCY – The delay
between when the controller starts looking
for a specific block of data on a track and
when that block rotates around to where it
can be read by the read/write head. On the
average, it is half of the time needed for a full
rotation (about 8 ms.).

S

SCSI – Acronym for Small Computer System
Interface, an American National Standards

Institute (ANSI) version of Shugart Associates'
SASI interface between the computer and
controller. SCSI has grown in popularity and
is one of the most flexible and intelligent
interfaces available.

SECTOR – A section of space along a track
on the disk, or the data that is stored in that
section. Hard disks most often have sectors
that are 512 data bytes long plus several bytes
overhead for error correcting codes. Each
sector is preceded by ID data known as a
header, which cannot be overwritten.

SEEK – A movement of the disk read/write
head in or out to a specific track.

SERVO DATA – Magnetic markings
written on the media that guide the
read/write heads to the proper position.

SERVO SURFACE – A separate surface
containing only positioning and disk timing
information but no data.

SETTLE TIME – The interval between
when a track to track movement of the head
stops, and when the residual vibration and
movement dies down to a level sufficient for
reliable reading or writing.

SHOCK RATING – A rating (expressed in
Gs) of how much shock a disk drive can
sustain without damage.

SOFT ERROR – An error in reading data
from the disk that does not recur if the same
data is reread. Often caused by power
fluctuations or noise spikes.

SOFT SECTORED – Disks that mark the
beginning of each sector of data within a track
by a magnetic pattern.

SPINDLE – The center shaft of the disk
upon which the drive’s platters are mounted.

SPUTTER – A type of coating process used
to apply the magnetic coating to some
high-performance disks. In sputtering, the
disks are placed in a vacuum chamber and the
coating is vaporized and deposited on the
disks. The resulting surface is hard, smooth,
and capable of storing data at high density.
Maxtor disk drives use sputtered thin film
disks.

STEPPER – A type of motor that moves in
discrete amounts for each input electrical
pulse. Stepper motors used to be widely used
for read/write head positioner, since they can
be geared to move the head one track per
step. Stepper motors are not as fast or reliable
as the rotary voice coil actuators which
Maxtor disk drives use.

SURFACE – The top or bottom side of the
platter which is coated with the magnetic
material for recording data. On some drives
one surface may be reserved for positioning
information.

T

THIN FILM – A type of coating, used for
disk surfaces. Thin film surfaces allow more
bits to be stored per disk.

TPI – Acronym for tracks per inch. The
number of tracks or cylinders that are written
in each inch of travel across the surface of a
disk.

U

UNFORMATTED CAPACITY – The
total number of bytes of data that could be fit
onto a disk. Formatting the disk requires some
of this space to record location, boundary
definitions, and timing information. After
formatting, user data can be stored on the
remaining disk space, known as formatted
capacity. The size of a Maxtor drive is
expressed in formatted capacity.

V

VOICE COIL – A type of motor used to
move the disk read/write head in and out to
the right track. Voice-coil actuators work like
loudspeakers with the force of a magnetic coil
causing a proportionate movement of the
head. Maxtor's actuator uses voice-coil
technology, and thereby eliminates the high
stress wearing parts found on stepper motor
type actuators.

TRACK – One of the many concentric
magnetic circle patterns written on a disk
surface as a guide to where to store and read
the data.

TRACK DENSITY – How closely the
tracks are packed on a disk surface. The
number is specified as tracks per inch (TPI).

TRACK TO TRACK SEEK TIME – The
time required for the read/write heads to
move to an adjacent track.

TRANSFER RATE – The rate at which the
disk sends and receives data from the
controller. Drive specifications usually
reference a high number that is the burst
mode rate for transferring data across the
interface from the disk buffer to system RAM.
Sustained data transfer is at a much lower rate
because of system processing overhead, head
switches, and seeks.

W

WEDGE SERVO – The position on every
track that contains data used by the closed
loop positioning control. This information is
used to fine tune the position of the
read/write heads exactly over the track
center.

WINCHESTER DISKS – Hard disks that
use a technology similar to an IBM model
using Winchester as the code name. These
disks use read/write heads that ride just above
the magnetic surface, held up by the air flow
created by the turning disk. When the disk
stops turning, the heads land on the surface,
which has a specially lubricated coating.
Winchester disks must be sealed and have a
filtration system since ordinary dust particles
are large enough to catch between the head
and the disk.

WRITE ONCE – In the context of optical
disks, technologies that allow the drive to
store data on a disk and read it back, but not
to erase it.
