Introduction
1-4 Maxtor DiamondMax 17 80-160GB Serial ATA Hard Drive
Serial ATA is a high-speed link replacement for the Parallel ATA attachment of mass
storage devices. The serial link employed is a high-speed differential layer that utilizes
Gigabit technology and 8b/10b encoding. This chapter will provide you with an
overview of key features of the DiamondMax 17 80-160GB Serial ATA hard disk
drive, performance data, reliability, and versatility data. Performance and installation
data are provided in chapters 3 and 4 respectively.
2.1 PRODUCT OVERVIEW
Maxtor is the one of the industry leader’s in developing Serial ATA (SATA) and
providing Serial ATA hard drives in volume.
Serial ATA 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 feature make SATA very attractive for ATA RAID
applications.
Chapter 2
General Description
The latest version of the Serial ATA interface used in the DiamondMax 17 doubles
the original maximum (burst) data transfer speed of 1.5Gb per second to 300MB per
second. This increase maximizes drive throughput for future growth in drive transfer
rates supporting data intensive environments.
The DiamondMax 17 Serial ATA hard disk drive features an embedded hard disk
drive controller, and uses ATA commands to optimize system performance. Because
the drive manages media defects and error recovery internally, these operations are
fully transparent to the user.
The innovative design of the DiamondMax 17 Serial ATA hard disk drive
incorporates leading edge technologies with transfer speeds up to 300MB/second,
Advanced Cache Management, Shock Protection System (SPS), Data Protection
System (DPS), Quiet Drive Technology (QDT), and Fly Height Adjust Technology.

full use of the mounting hole threads, while avoiding damaging or
placing unwanted stress on the PCB. The DiamondMax 17 80-160GB
Serial ATA specifies the minimum clearance between the PCB and the
screws in the mounting holes. To avoid stripping the mounting hole
threads, the maximum torque applied to the screws must not exceed
8 inch-pounds. A maximum screw length of 0.25 inches may
be used.
Figures 3-6 and 3-7 show airflow recommended for adequate cooling. Clearance from
the drive to any surface above and below the drive must be a minimum of 1.25mm.
Maxtor leaves the design and application of cooling and clearance for the disk drive
to the user, but the drive must maintain a case temperature at or below 60 ° C.

3.6 FOR SYSTEMS WITH AN ATA ADAPTER BOARD
To install the DiamondMax 17 80-160GB Serial ATA hard disk drive in an ATcompatible system without a Serial ATA connector, you need a third-party IDEcompatible adapter board.
To connect the DiamondMax 17 80-160GB Serial ATA drives, use the Serial ATA
cable, 1 meter long or shorter. The Serial ATA cable connectors are keyed to ensure
proper orientation.
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.

3.7 TECHNIQUES IN DRIVE CONFIGURATION
3.7.1 Operating System Limitations
Most popular operating systems available today have additional limitations which
affect the use of large capacity drives. However, these limitations can not be corrected
on the BIOS and it is up to the operating system manufacturers to release improved
versions to address these problems.
DOS and Windows 95 use a File Allocation Table (FAT) size of 16 bits which will only
support partitions up to 2.1GB. Windows 95 OSR2, Windows 98, and Windows ME
use a FAT size of 32 bits, allowing partitions of up to 2.2 terrabytes. Windows NT,
2000, and XP use NTFS, which allows partition sizes up to 16 terrabytes.
3.8 SYSTEM STARTUP AND OPERATION
Once you have installed the DiamondMax 17 80-160GB Serial ATA hard disk drive,
and adapter board (if required) in the host system, you are ready to partition and
format the drive for operation. To set up the drive correctly, follow these steps:
Installation
1.
Power on the system.
2. Run the SETUP program. This is generally on a Diagnostics or Utilities disk,
or within the system’s BIOS. Some system BIOS have an auto-detecting feature
making SETUP unnecessary.
3. Enter the appropriate parameters.
The SETUP program allows you to enter the types of optional hardware installed—
such as the hard disk drive type, the floppy disk drive capacity, and the display adapter
type. The system’s BIOS uses this information to initialize the system when the power
is switched on. For instructions on how to use the SETUP program, refer to the
system manual for your PC.
During the AT system CMOS setup, you must enter the drive type for the
DiamondMax 17 80-160GB Serial ATA hard drive. The drive supports the translation
of its physical drive geometry parameters such as cylinders, heads, and sectors per track
to a logical addressing mode. The drive can work with different BIOS drive-type
tables of the various host systems.
You can choose any drive type that does not exceed the capacity of the drive.
Table 3-2 gives the logical parameters that provide the maximum capacity on the
DiamondMax 17 80-160GB Serial ATA hard disk drives.

3.8.1 Big Drive Enabler (software download)
Maxtor’s Big Drive Enabler is a one step executable that enables support for drives
larger than 137 Gigabytes in Windows 2000 Service Pack 3 and XP Service Pack 1.
This utility takes the guess work out of editing the windows registry. The Big Drive
Enabler fixes an operating system limitations. This utility is needed anytime a hard
drive larger than 137GB is connected to a system’s ATA bus, regardless of any system
BIOS that supports 48-bit LBA.
Note: Failure to install the required service packs and install the Enabler Big LBA patch
can result in data loss when accessing the hard disk beyond 137GB. Refer to
Maxtor Knowledge Base Answer ID 960 and Microsoft Knowledge Base Article

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
of the disk to particular files. See also allocation unit.

positioning information and contains no data.
DEFECT MANAGEMENT
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.
DISK CONTROLLER

the disk. The Maxtor disk drives all have controllers
embedded on the drive printed-circuit board.
DISKWARE

FILE SERVER
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.

The number is usually stated as flux changes per inch (FCI),
with typical values in the thousands.
FLYING HEIGHT
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.

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.
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.
H
HALF HEIGHT – Term used to describe a 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 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.
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

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

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.
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.

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
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.

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

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.

capacity. See also kilobyte.
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 internal functions of the
drive and to support the embedded controller.
MICROSECOND (µs) – One millionth of a second
(.000001 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 = 1,000,200 / 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.

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 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.
POSITIONER – See actuator.
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.
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.
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.
Glossary
ROM
– Acronym for
of an ROM in the controller that contains programs that can
be accessed and read but not modified by the system.
ROTARY ACTUATOR
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 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.).

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 –
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.
SUBSTRATE
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.
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.
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.
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.

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.
