PRODUCT DESCRIPTION
2.1
PRODUCT DESCRIPTION
Maxtor drive leadership continues with the DiamondMax 8S 40GB Serial ATA drive
- a single head, 7200RPM product. The DiamondMax 8S 40GB Serial ATA drives
combine performance and value with the Serial ATA interface making a perfect
choice for entry level consumers and commercial/business desktop systems
transitioning to the new interface.
The Serial ATA interface provides the fastest desktop interface with maximum data
transfer rates of 1.5 Gb/s and additional features.
• Native Command Queuing to improve performance
• MHX Dual Processor Architecture maximizes the performance potential of
Serial ATA
Fluid Dynamic Bearing (FDB) motors minimize drive acoustics, allowing the drive to
operate with low sound output. DiamondMax 8S 40GB Serial ATA is designed for
higher reliability. The drive’s inner diameter load/unload ramp locks the recording
head into a protective carrier to cradle the head during shipment and any other time
the drive is not in operation.
DiamondMax 8S 40GB Serial ATA drive delivers high reliability and data integrity
and is enhanced using Maxtor developed Shock Protection System (SPS) and Data
Protection System (DPS). SPS and DPS give the user enhanced protection against
both operating and non-operating shock and verify essential functions in seconds to
minimize costly drive returns.
• Serial ATA, 1.5 Gb/s
• Native Command Queuing to improve performance
• MHX Dual Processor Architecture maximizes the performance potential of
Serial ATA
• No need to add or remove jumpers for simplified system configurations

2.2
THE SERIAL ATA INTERFACE
Serial ATA is the next generation ATA interface. It provides faster data transfer speeds,
more bandwidth, more potential for speed increases in future generations and better
data integrity. Serial ATA hardware is smaller and more compact than traditional
parallel ATA components. A powerful command set and hot plug features make Serial
ATA very attractive for RAID applications.
With a maximum external interface data transfer speed of 1.5 Gb/s, Serial ATA
improves hard drive performance to keep pace with increasing data intensive
environments such as audio/video, consumer electronics and entry-level servers.
Serial ATA brings these powerful benefits for storage solutions:
• Performance increase to 1.5Gb/s maximum external (burst) data transfer rate
• Thin cables for easy routing and improved cooling inside a PC chassis or JBOD
box
• Maximum cable length increases to 1 meter for increased design and layout
flexibility in a system
• Thinner cables improve system airflow and cooling efficiency
• Backward compatible with existing parallel ATA software and drivers, to allow
upgrading from ATA hardware to Serial ATA hardware without having to
change software drivers or applications.
For additional information about how Serial ATA emulates parallel ATA, refer to the
“Serial ATA: High Speed Serialized AT Attachment, revision 1.0a” specification. The

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 DiamondMax 8 SATA 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 dam-
age to the drive, do not use a sharp instrument to open the ESD
bag and do not touch PCB components. Save the packing mate-
rials for possible future use.
3. When you are ready to install the drive, remove it from the ESD bag.

HARDWARE OPTIONS
The configuration of a Maxtor DiamondMax 8S 40GB SATA 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.
4.3.1
4.3.2
Jumper Position
The DiamondMax 8S 40GB SATA interface connector shown in Figure 4-4
includes a position for a jumper. See section 4.3.2 Staggered Spin-up, for details on
how the jumper is used.
Staggered Spin-up
The staggered spin-up feature allows the host to control when a SATA drive initiates
spin-up. In a system with many drives, the host may choose not to spin all disk drives
at one time, but instead spin up the drives in a sequence. In the latter case, the host
“staggers” the time at which each drive spins-up.
DiamondMax 8S 40GB SATA implements the staggered spin-up feature as defined
by the SATA II Extensions to Serial ATA 1.0a revision 1.2 specification. After
power is applied to the drive, and before the first FIS is received, the drive samples
pin 11 on the power connector (See Figure 4-4 ). If the pin is sampled as low or
grounded, then Staggered Spin-up is disabled and the drive automatically spins up.
If the pin is sampled as floating or high, then Staggered Sign-up is enabled and the
drive waits for COMRESET and PHY initialization before spinning up. For more
details on SATA PHY initialization, see section 6.8 of the Serial ATA: High speed
Serialized AT Attachment Specification, revision 1.0a.

Installation
For systems using Serial ATA cables, the Serial ATA II specification mandates that
host systems connecting to disk drives using SATA cables must ground Pin 11,
resulting in disabling staggered spin-up. Typical desktop systems use this
configuration.
In backplane (non-cabled) environments or other systems that do not ground Pin
11, DiamondMax 8S 40GB SATA samples pin 11 after power up and before the first
FIS is received, detects the floating or high condition of Pin 11, and enables
staggered spin-up. In such a system, the host initiates spin-up by sending a
COMRESET signal to the drive.
Where Pin 11 has been grounded, but the system builder wants Staggered Spin-up
enabled, DiamondMax 8S drives allow use of a jumper to turn on Staggered Spin-
up mode. Using a jumper will force a staggered spin-up, overriding whatever state
is on Pin 11.
Putting a jumper across the jumper pins (See Figure 4-4) forces the drive to delay
spin-up, whether Pin 11 is grounded or not. In older systems where Pin 11 is
grounded, this method provides the ability to sequentially spin-up each drive in the
system. Table 4-1 shows the different configuration for staggered spin-up when
using Pin 11 or jumper.

Any State
Note: 1. Pin 11 must not exceed 3.6V.
Note: 2. If a jumper is required, Maxtor recommends a 2 position, low
profile shunt with 2 mm pitch and gold finish.
CAUTION: The PCB is very close to the mounting holes. Do not exceed the specified penetration for the
mounting screws. The specified screw penetration allows full use of the mounting hole threads,
while avoiding damaging or placing unwanted stress on the PCB. Figure 4-5 specifies the mini-
mum clearance between the PCB and the screws in the mounting holes.
The Maxtor hard drive design allows greater shock tolerance than that afforded by larger, heavi-
er drives. The drive may be mounted in any attitude using four size 6-32 screws with 3 mm
maximum penetration and a maximum torque of 5-inch pounds. Allow adequate ventilation to
the drive to ensure reliable operation.

4.4
MOUNTING
Drive mounting orientation, clearance, and ventilation requirements are described
in the following subsections.
4.4.1
Orientation
The mounting holes on the Maxtor DiamondMax 8S 40GB SATA hard disk drives
allow the drive to be mounted in any orientation. Figure 4-5 shows the location of
the three mounting holes on each side of the drive. The drive can also be mounted
using the four mounting hole locations on the PCB side of the drive.
Note: It is highly recommended that the drive is hard mounted on to
the chassis of the system being used for general operation, as well
as for test purposes. Failure to hard mount the drive can result in
erroneous errors during testing. Drives can be mounted in any
Figure 4-5 Mounting Screw Clearance
Maxtor DiamondMax 8S 40GB SATA

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

Installation
4.4.2
Ventilation
The Maxtor DiamondMax 8S 40GB SATA hard disk drives operate without a
cooling fan, provided the ambient air temperature does not exceed 140° F
(60° C).
4.5
COMMBINATION CONNECTOR (J1)
The DiamondMax 8S 40GB SATA is equipped with a serial ATA interface
connector with integrated power connector, as shown in Figure 4-4.
4.5.1
4.5.2
DC Power (J1, Section A)
The recommended mating connectors for the +5 VDC and +12 VDC input power
are listed in Table 4-2. Device Plug Connector Pin Definitions.
External Drive Activity LED
DiamondMax 8S 40GB SATA supports the activity LED through Pin 11 as defined
by the SATA II Extensions to Serial ATA 1.0a r1.2 specification. In systems with
SATA cables, the Serial ATA II spec mandates that pin 11 is grounded. However,
in a backplane environment or other system where Pin 11 is not grounded,
DiamondMax 8S may drive an “activity indicator LED” via pin 11.
After power up and before the first FIS is received, the drive samples pin 11 to detect
whether to enable/disable staggered spinup mode (see section 4.3.2). After sampling
Pin 11, Pin 11 is driven by the disk drive as needed to turn the LED on. Note that
pin 11 behaves like an open collector output, sinking current to activate an LED.
4.5.3
SATA Bus Interface Connector
There are two ways you can configure a system to allow the Maxtor DiamondMax
8S 40GB SATA hard disk drives to communicate over the Serial ATA bus of an IBM
or IBM-compatible PC:
1. Connect the drive to a Serial ATA bus connector on the motherboard of the PC.
2. Install an SATA adapter board in the PC, and connect the drive to the adapter
board.
To prevent the possibility of incorrect installation, the connector is polarized. This
ensures that a connector cannot be installed upside down.
See Chapter 6 “Cables and Connectors Specifications” in the “Serial ATA: High
Speed Serialized AT Attachment, Revision 1.0a” specification for more information
about cable and power requirements.

4.6
FOR SYSTEMS WITH A MOTHERBOARD CONTAINING AN
EMBEDDED SATA HOST
You can install the Maxtor DiamondMax 8S 40GB SATA hard disk drive in a SATA
compatible system that contains a SATA bus connector on the motherboard. To
connect the DiamondMax hard disk drive to the motherboard use a SATA cable to
connect the drive to the motherboard. Note that power and signal cables should be
connected before power is applied to the drive or motherboard.
4.7
FOR SYSTEMS WITH AN ADD-IN SATA ADAPTER BOARD
If your PC motherboard does not contain a built-in Serial ATA bus interface
connector, you must install a Serial ATA bus adapter board and connecting cable to
allow the drive to interface with the motherboard. Maxtor does not supply such an
adapter board, but they are available from several third-party vendors.
Please carefully read the instruction manual that comes with your adapter board to
ensure signal compatibility between the adapter board and the drive. Also, make sure
that the adapter board jumper settings are appropriate.
4.7.1
Connecting the Adapter Board and the Drive
1. Locate an available Serial ATA (SATA) port on your motherboard or on a SATA
PCI card and plug in one end of the SATA interface cable.
2. Locate the SATA port on the rear of the hard drive and plug in the SATA
interface cable as shown in Figure 4-7.
3. Secure the drive to the system chassis by using the mounting screws, as shown in
Figure 4-8.
Note: If you have an existing installation of Windows 2000 or XP, you
must install a Windows driver for the SATA interface before
connecting the drive. Suppliers of host adapters, motherboards,
and systems with embedded SATA, typically supply SATA driv-
ers. For maximum compatibility, Maxtor recommends down-
loading and installing the latest SATA driver from the website of
the host adapter, motherboard, or system manufacturer.

Note 2. Host system should ground P4,P5, and P6. Failure to do so may cause
improper drive operation.
The following points should be noted:
All pins are in a single row, with a 1.27 mm (.050”) pitch.
• The comments on the mating sequence apply to the case of
backplane blind mate connector only. In this case, the mating
sequences are: (1) the ground pins P4 and P12; (2) the pre-
charge power pins and the other ground pins; and (3) the
signal pins and the rest of the power pins.
• There are three power pins for each voltage. One pin from
each voltage is used for pre-charge in the backplane blind-
mate situation.
• If a device uses 3.3 V, then all V33 pins must be terminated.
Otherwise, it is optional to terminate any of the V33 pins. If a
device uses 5.0 V, then all V5 pins must be terminated.
Otherwise, it is optional to terminate any of the V5 pins.
• If a device uses 12.0 V, then all V12 pins must be terminated.
Otherwise, it is optional to terminate any of the V12 pins.

GLOSSARY
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.
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.
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.
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.
BLOCK – A sector or group of sectors. By
default, a block of data consists of 512 bytes.
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.
ALLOCATION – The process of assigning
particular areas of the disk to particular files.
See also allocation unit.
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.
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.
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.
C
B
CACHE – Random-access memory used as a
buffer between the CPU and a hard disk.
Information more likely to be read or changed
is placed in the cache, where it can be accessed
more quickly to speed up general data flow.
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.
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.
BAD BLOCK – A block (usually the size of
a sector) that cannot reliably hold data because
of a media flaw or damaged format markings.
CDB – Command Descriptor Block. The
BAD TRACK TABLE – A label affixed to

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.
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.
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.
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.
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
CPU – Acronym for Central Processing Unit.
The microprocessor chip that performs the
bulk of data processing in a computer.
embedded on the drive printed-circuit board.
DISKWARE – The program instructions
and data stored on the disk for use by a
processor.
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.
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.
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.
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.
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.
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.
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
Maxtor DiamondMax 8S 40GB SATA
G-2
GLOSSARY
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.
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.
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.
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.
EOF - End Of Frame
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.
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.
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.
FRAME - A frame is an indivisible unit of
information exchanged between a host and
device. A frame consists of a SOF (Start Of
Frame) primitive, a Frame Information
Structure, a CRC calculated over the
contents of the FIS, and an EOF (End Of
Frame) primitive.
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

G
GIGABYTE (GB) – One billion bytes (one
thousand megabytes).
GUIDE RAILS – Plastic strips attached to
the sides of a disk drive mounted in an IBM
AT and compatible computers so that the
drive easily slides into place.

GLOSSARY
HARD DISK – A type of storage medium
that retains data as magnetic patterns on a rigid
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.
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.
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.
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).
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.
J
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.
HOME – Reference position track for
re-calibration of the actuator, usually the
outer track (track 0).
JBOD - Just a Bunch of Drives
HOST ADAPTER – A plug-in board that
forms the interface between a particular type
of computer system bus and the disk drive.
K
KILOBYTE (kB) – A unit of measure
consisting of 1,024 (210) bytes.
I
INITIALIZE – See low level formatting.
L
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.
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.
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.
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.
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.
LOOK AHEAD – The technique of
buffering data into cache RAM by reading
Maxtor DiamondMax 8S 40GB SATA

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 /

included in this number as this type of repair
is not performed in the field.
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

the data is stored inside the disk in the form of
magnetic flux or polarity changes.
O
OVERHEAD – The processing time of a
command by the controller, host adapter or
drive prior to any actual disk accesses taking
place.
MEGABYTE (MB) – A unit of

magnetic coatings are combinations of iron or
other metal oxides, and the term has become
a general one for the magnetic coating on tape
or disk.
See also kilobyte.
MEGAHERTZ – A measurement of
frequency in millions of cycles per second.
P
MHz – See megahertz.
PARTITION – A portion of a hard disk
devoted to a particular operating system and
accessed as one logical volume by the system.
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
internal functions of the drive and to support
the embedded controller.
PERFORMANCE– A measure of the speed
of the drive during normal operation. Factors
affecting performance are seek times, transfer
rate and command overhead.
PERIPHERAL– A device added to a system
as an enhancement to the basic CPU, such as
a disk drive, tape drive or printer.

GLOSSARY
PLATED MEDIA – Disks that are covered
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.
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.
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.
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.
POH – Acronym for power on hours. The unit
of measurement for Mean Time Between
Failure as expressed in the number of hours
that power is applied to the device regardless
of the amount of actual data transfer usage.
See MTBF.
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.
POSITIONER – See actuator.
ROM – Acronym for read only memory.
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.
R
RAM – Acronym for random access memory.
An integrated circuit memory chip which
allows information to be stored and retrieved
by a microprocessor or controller. The
information may be stored and retrieved in
any order desired, and the address of one
storage location is as readily accessible as any
other.
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.
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.
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.).
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.
S
Serial ATA (SATA) - Serial ATA (Serial
Advanced Technology Attachment or SATA)
is a standard for connecting hard drives to
computers. The Serial ATA standard defines a
physical interface that uses serial signaling
technology unlike the ATA standard
(sometimes referred to as Parallel ATA that
uses parallel technology.
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.

GLOSSARY
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.
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.
SOF - Start Of Frame
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.
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.
SUBSTRATE – The material the disk
platter is made of beneath the magnetic
coating. Hard disks are generally made of
aluminum or magnesium alloy (or glass, for
optical disks) while the substrate of floppies is
usually mylar.
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.
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.
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.
T
THIN FILM – A type of coating, used for
disk surfaces. Thin film surfaces allow more
bits to be stored per disk.
SHOCK RATING – A rating (expressed in
Gs) of how much shock a disk drive can
sustain without damage.
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.
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.
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.
SOFT SECTORED – Disks that mark the
beginning of each sector of data within a track
by a magnetic pattern.
TRACK DENSITY – How closely the
tracks are packed on a disk surface. The
number is specified as tracks per inch (TPI).
SPINDLE – The center shaft of the disk
upon which the drive’s platters are mounted.
TRACK TO TRACK SEEK TIME – The
time required for the read/write heads to
move to an adjacent track.
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
TRANSFER RATE– The rate at which the
Maxtor DiamondMax 8S 40GB SATA

GLOSSARY
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.
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.
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.
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.
