operation:  
– CS – Cable Select  
– DS – Drive Select  
– CLJ– Cylinder Limitation Jumper  
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.

Installation  
3.3.1.1  
Cable Select (CS) Jumper  
When a DiamondMax 17 80-160GB AT hard disk drive and another ATA 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 Master or Slave with the CS  
feature, the CS jumper is installed (1). The drive's position on the 80 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 ATA 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 ATA 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 ATA bus  
connector. This allows two drives to operate in a Master/Slave relationship  
according to the drive cable placement.  
The DiamondMax 17 80-160GB AT 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  
3.3.1.3  
Drive Select (DS) Jumper  
You can also daisy-chain two drives on the ATA 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.  
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:  
Note: 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  
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.  
A summary of these effects for the DiamondMax 17 80-160GB AT drives is shown  
in the following table:

ATA Bus Adapter  
There are two ways you can configure a system to allow the DiamondMax 17  
80-160GB AT hard disk drives to communicate over the ATA bus of an IBM  
or IBM-compatible PC:  
1. Connect the drive to a 40-pin ATA 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.

Installation  
3.3.2.1  
40-Pin ATA Bus Connector  
Most PC motherboards have a built-in 40-pin ATA bus connector that is  
compatible with the 40-pin ATA interface of the DiamondMax 17 80-160GB  
AT hard disk drives. If the motherboard has an ATA connector, simply connect  
a 40-pin ribbon cable between the drive and the motherboard.  
You should also refer to the motherboard instruction manual to ensure signal  
compatibility.  
3.3.2.2  
Adapter Board  
If your PC motherboard does not contain a built-in 40-pin ATA bus interface  
connector, you must install an ATA 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.

The mounting holes on the DiamondMax 17 80-160GB AT hard disk drives allow  
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.  
Note: Drives can be mounted in any orientation. Normal position is with the PCB  
facing down.  
All dimensions are in millimeters. For mounting, #6-32 UNC screws are  
recommended.

CAUTION: The PCB is very close to the mounting holes. Do not ex-  
ceed the specified length for the mounting screws. The  
specified screw length allows full use of the mounting hole  
threads, while avoiding damaging or placing unwanted stress  
tween 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.

Clearance  
Clearance from the drive to any other surface (except mounting surfaces) must be a  
minimum of 1.25 mm (0.05 inches).  
Ventilation  
The DiamondMax 17 80-160GB AT hard disk drives operate without a cooling fan,  
provided the base casting temperature as measured where the motor is attached to the  
base does not exceed 140°F (60°C). Drive reliability and warranty will be limited if  
the drive is exposed to temperatures greater than 60°C when operating and/or  
temperatures greater than 70°C when in storage/not operating.  
Figures 3-8 and 3-9 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.

FOR SYSTEMS WITH AN ATA ADAPTER BOARD  
To install the DiamondMax 17 80-160GB AT hard disk drive in an AT-compatible  
system without a 40-pin ATA 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.  
computer before installing the drive.

Installation  
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 3-10.  
To connect the drive to the board:  
1. Insert the 40-pin cable connector 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.  
3. Secure the drive to the system chassis by using the mounting screws.

TECHNIQUES IN DRIVE CONFIGURATION  
The 8.4-Gigabytes Barrier  
3.7.1  
Newer BIOS’s allow users to configure disk drives to go beyond the 528MB barrier  
by using several BIOS translation schemes. However, while using these translations  
the BIOS using Int 13 functions are limited to 24 bits of addressing which results in  
another barrier at the 8.4GB capacity.  
To overcome this barrier a new set of Int 13 extensions are being implemented by  
most BIOS manufacturers. The new Int 13 extension allows for four words of  
addressing space (64 bits) resulting in 9.4 Terrabytes of accessible space.  
Whenever possible the DiamondMax 17 80-160GB AT drive should be used on  
systems with BIOS that support Int 13 extensions. If that is not possible the  
following are some techniques that can be used to overcome this barrier:  
– Use a third party software that supplements the BIOS and adds Int 13  
extension support.  
– Obtain a BIOS upgrade from the system board manufacturer. Many system  
board manufacturers allow their BIOS to be upgraded in the field using  
special download utilities. Information on BIOS upgrades can be obtained on  
the System Board Customer Service respective web sites on the Internet.  
– Insert the Cylinder Limitation Jumper (CLJ) on the drive (see Section 3.3.1.4).  
3.7.2  
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 2.1 GB. 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.

SYSTEM STARTUP AND OPERATION  
Once you have installed the DiamondMax 17 80-160GB AT 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:  
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.  
Note: The SETUP program allows you to enter the types of optional hardware in-  
stalled—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.  
Note: During the AT system CMOS setup, you must enter the drive type for the  
DiamondMax 17 80-160GB AT hard disk drives. 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.  
Note: You can choose any drive type that does not exceed the capacity of the drive.

Glossary  
BLOCK – A sector or group of sectors.  
A
ACCESS– (v) Read, write, or update information on some  
storage medium, such as a disk. (n) One of these operations.  
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.  
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.  
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.  
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.  
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
ALLOCATION – The process of assigning particular areas  
of the disk to particular files. See also allocation unit.  
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.  
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.  
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.  
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.  
CDB – Command Descriptor Block. The SCSI structure  
used to communicate requests from an initiator (system) to  
a target (drive).  
B
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.  
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.  
CLUSTER – A group of sectors on a disk drive that is  
addressed as one logical unit by the operating system.  
BAD BLOCK – A block (usually the size of a sector) that  
cannot reliably hold data because of a media flaw or  
damaged format markings.  
CONTROLLER – Short form of disk controller. The chip  
or complete circuit that translates computer data and  
commands.  
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.  
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.  
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.  
Maxtor DiamondMax 17 80-160GB AT Hard Disk Drive  
G-1  
 
Glossary  
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.  
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.  
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.  
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.  
D
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.  
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.  
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.  
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.  
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  
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.  
simultaneously as a file server and a workstation.  
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.  
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.  
DISKWARE – The program instructions and data stored  
on the disk for use by a processor.  
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.  
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.  
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.  
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.  
G-2 Maxtor DiamondMax 17 80-160GB AT Hard Disk Drive  
 
Glossary  
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.  
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.  
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.  
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.  
G
GIGABYTE (GB) – One billion bytes (one thousand  
megabytes).  
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.  
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.  
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.  
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.  
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).  
K
HARD ERROR – A repeatable error in disk data that  
persists when the disk is reread, usually caused by defects in  
the media surface.  
KILOBYTE (Kb) – A unit of measure consisting of 1,024  
10  
(2 ) bytes.  
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.  
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.  
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.  
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.  
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.

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  
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.  
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.  
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.  
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.  
O
LOW PROFILE– Describes drives built to the 3 1/2-inch  
OVERHEAD – The processing time of a command by the  
controller, host adapter or drive prior to any actual disk  
accesses taking place.  
form factor, which are only 1 inch high.  
M
OVERWRITE – To write data on top of existing data,  
erasing it.  
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.  
OXIDE – A metal-oxygen compound. Most 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.  
P
MEGABYTE (Mb) – A unit of measurement equal to  
1,024 kilobytes, or 1,048,576 bytes except when referring to  
disk storage capacity.  
PARTITION – A portion of a hard disk devoted to a  
particular operating system and accessed as one logical  
volume by the system.  
1 MB = 1,000,000 bytes when referring to disk storage  
capacity. See also kilobyte.  
PERFORMANCE – A measure of the speed of the drive  
during normal operation. Factors affecting performance are  
seek times, transfer rate and command overhead.  
MEGAHERTZ– A measurement of frequency in millions  
of cycles per second.  
PERIPHERAL – A device added to a system as an  
enhancement to the basic CPU, such as a disk drive, tape  
drive or printer.  
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.  
PHYSICAL FORMAT – The actual physical layout of  
cylinders, tracks, and sectors on a disk drive.  
PLATED MEDIA – Disks that are covered with a hard  
metal alloy instead of an iron-oxide compound. Plated

Glossary  
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.  
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.  
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.  
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.  
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.).  
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.  
S
SATA - Acronym for Serial ATA.  
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.  
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.  
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.  
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.  
SEEK – A movement of the disk read/write head in or out  
to a specific track.  
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.  
SERVO DATA – Magnetic markings written on the media  
that guide the read/write heads to the proper position.  
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.  
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.  
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.  
SHOCK RATING – A rating (expressed in Gs) of how  
much shock a disk drive can sustain without damage.  
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.  
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.

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