UNPACKING INSTRUCTIONS  
CAUTION: The maximum limits for physical shock can be exceeded if the  
drive is not handled properly. Special care should be  
taken not to bump or drop the drive. It is highly recommended  
that Maxtor Quickview 300 drives are not stacked or placed on  
any hard surface after they are unpacked. Such handling could  
cause media damage.  
1. Open the shipping container and remove the packing assembly  
that contains the drive.  
2. Remove the drive from the packing assembly.  
CAUTION: During shipment and handling, the antistatic electrostatic dis-  
charge (ESD) bag prevents electronic component  
damage due to electrostatic discharge. To avoid accidental 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  
3.3.1  
PATA Interface Connector  
The configuration of a Quickview 300 PATA hard disk drive depends on  
the host system in which it is to be installed. This section describes the  
hardware options that you must take into account prior to installation.  
Figure 3-3 Jumper Locations on the PATA Interface Connector  
3-4 Quickview 300 80/100/120/160/200/250/300GB PATA  
Installation  
The configuration of the following three jumpers controls the drive’s five  
modes of operation:  
• CS –  
• DS –  
Cable Select  
Drive Select  
• CLJ– Cylinder Limitation Jumper  
• POSB - Power on standby (Remote Command)  
The AT PCB has two jumper locations provided to configure the drive in  
a system. The default configuration for the drive as shipped from the  
factory is with a jumper across the CS location, and open positions in  
the DS and CLJ positions.  
Table 3-1 defines the operation of the master/slave jumpers and their  
function relative to pin 28 on the interface. 1 indicates that the specified  
jumper is installed; 0 indicates that the jumper is not installed.

3.3.1.1 Cable Select (CS) Jumper  
When a Quickview 300 PATA hard disk drive and another PATA hard  
disk drive are daisy-chained together, they can be configured as Master  
or Slave either by the CS or DS jumpers. To configure the drive as a  
Quickview 300 80/100/120/160/200/250/300GB PATA  
3-5  
 
Installation  
Master or Slave with the CS feature, the CS jumper is installed (1). The  
drive's position on the 80 pin conductor Ultra ATA data cable then  
determines whether the drive is a Master (Device 0) or a Slave (Device  
1). If the drive is connected to the end of the Ultra (cable Select) data  
cable the drive is a Master. If the drive is connected to the middle  
connection it is set as a Slave.  
Once you install the CS jumper, the drive is configured as a Master or  
Slave by the state of the Cable Select signal: pin 28 of the PATA bus  
connector. Please note that pin 28 is a vendor-specific pin that Maxtor  
is using for a specific purpose. More than one function is allocated to  
CS, according to the PATA CAM specification (see reference to this  
specification in Chapter 1). If pin 28 is a 0 (grounded), the drive is  
configured as a Master. If it is a 1 (high), the drive is configured as a  
Slave. In order to configure two drives in a Master/Slave relationship  
using the CS jumper, you need to use a cable that provides the proper  
signal level at pin 28 of the PATA bus connector. This allows two drives  
to operate in a Master/Slave relationship according to the drive cable  
placement.  
The Quickview 300 PATA hard disk drives are shipped from the factory  
as a Master (Device 0 - CS jumper installed). To configure a drive as a  
Slave (Device 1- DS scheme), the CS jumper must be removed. In this  
configuration, the spare jumper removed from the CS position may be  
stored on the PK jumper pins.  
3.3.1.2 Drive Select (DS) Jumper  
You can also daisy-chain two drives on the PATA bus interface by using  
their Drive Select (DS) jumpers. To use the DS feature, the CS jumper  
must not be installed.  
To configure a drive as the Master (Device 0), a jumper must be installed  
on the DS pins.  
Note: The order in which drives are connected in a daisy chain  
has no significance.  
3.3.1.3 Master Jumper Configuration  
In combination with the current DS or CS jumper settings, the Slave  
Present (SP) jumper can be implemented if necessary as follows:  
The CS position doubles as the Slave present on this drive.  
• When the drive is configured as a Master (DS jumper installed  
or CS jumper installed, and the Cable Select signal is set to  
(0), adding an additional jumper (both jumpers DS and CS now  
installed) will indicate to the drive that a Slave drive is  
present. This Master with Slave Present jumper configuration  
should be installed on the Master drive only if the Slave drive  
does not use the Drive Active/Slave Present (DASP–) signal  
to indicate its presence.

Installation  
3.3.1.4 Power On Standby  
Upon power on, the drive will not spin up and will be in a power saving mode,  
irrespective of the other jumper settings.  
To spin up the drive, issue a Set Feature (OxEF) command with a sub-code 7.  
In the power saving mode, the drive will reject all other commands.  
Jumpers Setup  
Drive will spin up as normal drive and become ready in a few seconds after power  
up if the jumpers on pin 42 and pin 44 were not set.  
3.3.1.5 Cylinder Limitation Jumper (CLJ)  
For user capacities below 66,055,248 sectors (32GB), inserting the CLJ  
jumper limits the Number of Cylinders field 1 to a value of 16,383, as  
reported in IDENTIFY DEVICE data word. This allows software drivers  
to determine that the actual capacity is larger than indicated by the  
maximum CHS, requiring LBA addressing to use the full capacity.  
A summary of these effects for the Maxtor Quickview 300 hard drives  
is shown in the following table:

3.3.2  
PATA BUS ADAPTER  
There are two ways you can configure a system to allow the Maxtor  
hard disk drives to communicate over the PATA bus of an IBM or IBM-  
compatible PC:  
1. Connect the drive to a 40-pin PATA bus connector (if available) on  
the motherboard of the PC.  
2. Install an IDE-compatible adapter board in the PC, and connect  
the drive to the adapter board.  
3.3.2.1 40-Pin PATA Bus Connector  
Most motherboards have a built-in 40-pin PATA bus connector that is  
compatible with the 40-pin PATA interface of the Quickview 300 80/  
100/120/160/200/250/300GB PATA hard disk drives. If the  
motherboard has an PATA connector, simply connect a 80-pin  
conductor ribbon cable between the drive and the motherboard.  
You should also refer to the motherboard instruction manual to ensure  
signal compatibility.  
3.3.2.2 Adapter Board  
If your PC motherboard does not contain a built-in 40-pin PATA bus  
interface connector, you must install an PATA bus adapter board and  
connecting cable to allow the drive to interface with the motherboard.  
Please carefully read the instruction manual that comes with your  
adapter board, as well as Chapter 5 of this manual to ensure signal  
compatibility between the adapter board and the drive. Also, make sure  
that the adapter board jumper settings are appropriate.  
3.4  
COMBINATION CONNECTOR (J1)  
J1 is a three-in-one combination connector. The drive’s DC power can  
be applied to section A. The PATA bus interface (40-pin) uses section  
C. The connector is mounted on the back edge of the printed-circuit  
board (PCB), as shown in Figure 3-5.

PATA Bus Interface Connector (J1, Section C)  
On the Quickview 300 80/100/120/160/200/250/300GB PATA hard  
disk drives, the PATA bus interface cable connector (J1, section C) is a  
40-pin Universal Header, as shown in Figure 3-5.  
To prevent the possibility of incorrect installation, the connector has  
been keyed by removing Pin 20. This ensures that a connector cannot  
be installed upside down.  
See Chapter 5, “PATA Bus Interface and PATA Commands,” for more  
detailed information about the required signals. Refer to Table 5-1 for  
the pin assignments of the PATA bus connector (J1, section C).

Mounting  
3.5.1  
Orientation  
The mounting holes on the Quickview 300 80/100/120/160/200/250/  
300GB PATA hard disk drives allow the drive to be mounted in any  
orientation. Figure 3-7 and Figure 3-6 show 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 orientation. Normal posi-  
tion is with the PCB facing down.  
All dimensions are in millimeters. For mounting, #6-32 UNC screws are  
recommended.

Figure 3-7 Mounting Screw Clearance for the Maxtor Quickview 300 Hard Disk Drives  
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  
on the PCB. Figure 3-7 specifies the minimum clearance be-  
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.

Ventilation  
The Maxtor Quickview 300 80/100/120/160/200/250/300GB PATA  
hard disk drives operate without a cooling fan, provided the base casting  
temperature as measured where the motor is attached to the base  
casting does not exceed 158° F (70° C).  
For Systems With A Motherboard PATA Adapter  
You can install the Maxtor Quickview 300 80/100/120/160/200/250/  
300GB PATA hard disk drives in an AT-compatible system that contains  
a 40-pin PATA bus connector on the motherboard.  
To connect the drive to the motherboard, use a 80 conductor ribbon  
cable 18 inches in length or shorter. Ensure that pin 1 of the drive is  
connected to pin 1 of the motherboard connector.  
3.6  
For Systems With An PATA Adapter Board  
To install the 80/100/120/160/200/250/300GB PATA hard disk drive  
in an AT-compatible system without a 40-pin PATA bus connector on  
its motherboard, you need a third-party IDE-compatible adapter board.  
3.6.1  
Adapter Board Installation  
Carefully read the manual that accompanies your adapter board before  
installing it. Make sure that all the jumpers are set properly and that  
there are no address or signal conflicts. You must also investigate to see  
if your AT-compatible system contains a combination floppy and hard  
disk controller board. If it does, you must disable the hard disk drive  
controller functions on that controller board before proceeding.  
Once you have disabled the hard disk drive controller functions on the  
floppy/hard drive controller, install the adapter board. Again, make sure  
that you have set all jumper straps on the adapter board to avoid  
addressing and signal conflicts.  
Note: For Sections 3.5.4 thru 3.6, power should be turned off  
on the host system before installing the drive.

Subpart J of Part 15 of FCC Rules (47CFR15) or the Canadian  
Department of Communications Radio Interference Regulations.  
Although not required, the disk mechanism has been tested within a  
suitable end-use product and found to comply with Class B limits of the  
FCC Rules and Regulations of the Canadian Department of  
Communications.  
The CE Marking indicates conformity with the European Union Low  
Voltage Directive (73/23/EEC) when the disk mechanism is installed in  
a typical personal computer. Maxtor recommends that testing and  
analysis for EMC compliance be performed with the disk mechanism  
installed within the user's end-use application.

ATA BUS INTERFACE AND ATA COMMANDS  
This chapter describes the interface between the Quickview 300 hard  
disk drives and the PATA bus. The commands that are issued from the  
host to control the drive are listed, as well as the electrical and  
mechanical characteristics of the interface.  
5.1  
INTRODUCTION  
Maxtor Quickview 300 hard disk drives use the standard ATA/ATAPI  
interface. Support of various options in the standard are explained in  
the following sections.  
5.2  
MECHANICAL INTERFACE  
Signal Cable and Connector  
5.2.1  
The Quickview 300 hard disk drive contains a 40-pin unitized  
connector for both signal and power connections as well as  
configuration jumpers. The dimensions and specifications of the  
unitized connector comply with Annex. A in the ATA/ATAPI standard.  
The Quickview 300 drives require the use of an 80 conductor cable  
(ATA/ATAPI-6, Annex. A, Figure A.4 and description) to support the  
drive’s Ultra DMA capability.  
5.3  
ELECTRICAL INTERFACE  
PATA Bus Interface  
5.3.1  
5.3.1.1 Electrical Characteristics  
Signals on the PATA interface are assigned to connector pins according  
to Annex. A in the ATA/ATAPI-6 standard for the 80 conductor cable  
assembly. The signaling protocol complies with clause 9 and signal timing  
complies with clause 10 of the standard.  
The Quickview 300 hard disk drives support all Ultra DMA Data Transfer  
modes (0 - 5) defined in the ATA/ATAPI-6 standard and are ATA/ATAPI-  
7 compliant. In addition, these drives support Mode 6, and can send and  
receive data at the full 133MB/s transfer rate.  
Quickview 300 80/100/120/160/200/250/300GB PATA  
5-1  
ATA Bus Interface and ATA Commands  
Hosts may assert the RESET- signal for longer than the minimum. When  
power is applied with RESET- asserted, the Quickview 300 disk media  
will not begin to spin up until RESET- is negated. This may reduce  
maximum current consumption for the overall system.  
5.4  
REGISTER ADDRESS DECODING  
The Quickview 300 hard disk drives allow their host systems to address  
the full set of command and control registers as specified in clause 7 of  
the ATA/ATAPI-6 standard.  
5.5  
COMMAND INTERFACE  
General Feature Set  
5.5.1  
The µProcessor, Disk Controller, and PATA Interface electronics are  
contained in a proprietary ASIC developed by Maxtor.  
5.5.2  
Supported Commands  
The Quickview 300 hard disk drives support all the mandatory  
commands from the general feature set for devices not supporting the  
Packet command feature set. Refer to the ATA/ATAPI-6 standard for a  
detailed description of these commands. The IDENTIFY DRIVE command,  
Note: 1. As defined in the ATA/ATAPI-6 standard.

BREAKING THE 137 GIGABYTE STORAGE  
BARRIER  
This appendix provides information about the 137GB storage barrier. It  
discusses the history, cause and the solution to overcome this barrier.  
A.1  
Breaking the 137 Gigabyte Storage Barrier  
Capacity barriers have been a fact of the personal computer world since  
its beginnings in the early 1980’s. At least 10 different capacity barriers  
have occurred in the storage industry over the last 15 years. The most  
notable barriers seen previously have been at 528 megabytes and then at  
8.4 gigabytes.  
The ANSI NCITS T13 Technical Committee (also known as the ANSI ATA  
committee) has broken this barrier by incorporating a proposal from  
Maxtor into the ATA/ATAPI-6 draft standard that defines a method for  
48-bit addressing on a single drive, giving more than 144 petabytes  
(144,000 gigabytes) of storage.  
In addition, the proposal from Maxtor that was incorporated into ATA/  
ATAPI-6 defines a method for extending the maximum amount of data  
that can be transferred per command for ATA devices from 256 sectors  
(about 131 kilobytes) to 65,536 sectors (about 33 megabytes). This new  
method is particularly useful for applications that use extremely large  
files, such as those for A/V or multimedia.  
The following sections will describe issues surrounding the 137-gigabyte  
barrier and the solution for breaking it.  
A.1.1  
History  
Many of the “barriers” in the past resulted from BIOS and operating  
system issues caused by failure to anticipate the remarkable increases in  
device storage capacity by the people who designed hard disk structures,  
access routines, and operating systems many years ago. They thought,  
“Who will ever have xxx much storage?” In some cases, the barriers were  
caused by hardware or software bugs not found until hard disks had  
grown in size beyond a certain point where the bugs would occur.  
Past barriers often frustrated people trying to add a new hard disk to an  
older system when they discovered that not all of the designed capacity

Breaking the 137GB Storage Barrier  
of the hard disk was accessible. This inability to access the entire drive is  
referred to as a “capacity barrier” and it has been seen and overcome  
many times in the computer and disk drive industry.  
The 137-gigabyte barrier is the result of the original design specification  
for the ATA interface that provided only 28 bits of address for data. This  
specification means a hard disk can have a maximum of 268,435,456  
sectors of 512 bytes of data which puts the ATA interface maximum at  
137.4 gigabytes.

A.1.2  
Solving the 137 Gigabyte Capacity Barrier  
As described earlier, the issue causing the 137-gigabyte barrier is the 28-  
bit addressing method of the original ATA specification. A change to  
expand this method was required to provide more address bits for the  
interface, allowing significant growth for many years to come. A critical  
issue in expanding the addressing capability was maintaining  
compatibility with the existing installed base of products.  
The new ATA standard, ATA/ATAPI-6, resolves this issue by increasing  
the maximum number of bits used for addressing from 28 to 48. This  
solution increases the maximum capacity of an ATA device to 144  
petabytes while maintaining compatibility with current ATA products.  
A.1.3  
How is the Extension Implemented?  
The 48-bit Address feature set provides a method to address devices with  
capacities up to approximately 144 petabytes by increasing the number  
of bits used to specify logical block addresses (LBAs) from 28 to 48. The  
feature set also provides a method to increase the number of sectors that  
can be transferred by a single command from 256 to 65,536 by  
increasing the number of bits specifying sector count to 16 bits.  
New commands specific to this feature set have been defined so that  
devices can implement the new feature set in addition to previously  
defined commands. Devices implementing the 48-bit Address feature set  
commands will also implement commands that use 28-bit addressing in  
order to maintain interoperability with older system components. In  
addition, 8-bit and 48-bit commands may be intermixed.  
The 48-bit Address feature set operates in LBA addressing only. Support  
of the 48-bit Address feature set is indicated in the IDENTIFY DEVICE  
response data. In a device implementing the 48-bit Address feature set,  
the registers used for addressing are, in fact, a two-byte deep FIFO. Each  
time one of these registers is written, the new content written is placed  
into the “most recently written” location and the previous content of the  
register is moved to “previous content” location. A host may read the  
“previous content” of the registers by first setting a bit in the Device  
Control register to 1 and then reading the desired register.  
A.1.4  
What Do the Drives Need to Meet the Spec?  
The challenge to drive manufacturers is to develop and implement new  
interface chips on drives that can accept and decode the new 48-bit  
addressing scheme. Many functions of decoding the commands sent to  
and from the drive are automated in the silicon of the drive interface  
ASIC, and this is where drive manufacturers must update their designs.  
Maxtor is the leader in development efforts and is the first to deliver a  
product with the capacity and drive technology to deliver greater than  
137 gigabytes of capacity.

A-3  
Breaking the 137GB Storage Barrier  
A.1.5  
What Else is Involved?  
Effort is required from OS vendors to increase storage device addressing  
up to 48 bits or more. This increase will be a significant challenge for  
many OS vendors that have 32-bit code models. Adapting to 48-bit  
commands will be easy, but most vendors will stop filling data at the 32-  
bit boundary and pad the upper 16 bits with zeros, leaving that space  
empty.  
The BIOS companies will also have to perform some work to recognize  
the increased capacity of the devices attached to the bus and allow the  
extended 48-bit commands to pass on to the devices. Boot partitions will  
also be an issue for the capacity of the drive if the BIOS does not  
recognize the 48-bit addressing scheme at or before the system boots the  
OS from the hard drive.  
Independent software driver efforts for legacy operating systems  
(Windows NT 4, Windows 98, and so on) will need to be implemented to  
allow higher-capacity devices to work on installed systems and recognize  
the maximum available capacity of the drive over the 137-gigabyte limit.  
A.1.6  
What is the Next Barrier?  
While it is true that the ATA/ATAPI-6 standard defines a method to  
provide a total capacity for a device of 144 petabytes, the next limit will  
be imposed not by the ATA devices but by many of the popular operating  
systems in use today. This limit will be at 2.2 terabytes (2,200  
gigabytes). This barrier exists because many of today’s operating  
systems are based on 32-bit addressing. These operating systems include  
many flavors of Linux, Mac OS 9.x, and Windows 95, 98, ME, NT 4,  
2000, and XP (Windows XP/64-bit also has the limit because of leveraged  
32-bit code).  
This barrier could be real as early as 2004 if current hard drive capacity  
rate increases continue along the same growth trends.

A
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.  
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.  
BAD BLOCK – A block (usually the size of  
a sector) that cannot reliably hold data because  
of a media flaw or damaged format markings.  
BAD TRACK TABLE – A label affixed to  
the casing of a hard disk drive that tells which  
tracks are flawed and cannot hold data. The  
listing is typed into the low-level formatting  
program when the drive is being installed.  
Because Maxtor disk drive’s  
defect-management scheme handles all such  
flaws automatically, there is no need to  
concern yourself with bad track tables.  
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.  
BIT – Abbreviation for binary digit. A binary  
digit may have one of two values—1 or 0.  
This contrasts with a decimal digit, which  
may have a value from 0 to 9. A bit is one of  
the logic 1or logic 0 binary settings that make  
up a byte of data. See also byte.  
ALLOCATION – The process of assigning  
particular areas of the disk to particular files.  
See also allocation unit.  
BLOCK – A sector or group of sectors. By  
default, a block of data consists of 512 bytes.  
ALLOCATION UNIT – An allocation  
unit, also known as a cluster, is a group of  
sectors on the disk that can be reserved for the  
use of a particular file.  
AVERAGE SEEK TIME – The average  
time it takes for the read/write head to move  
to a specific location. To compute the average  
seek time, you divide the time it takes to  
complete a large number of random seeks all  
over the disk by the number of seeks  
performed.

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

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.  
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.  
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

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.  
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.  
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.  
O
OVERHEAD – The processing time of a  
command by the controller, host adapter or  
drive prior to any actual disk accesses taking  
place.  
POSITIONER – See actuator.  
OVERWRITE – To write data on top of  
existing data, erasing it.  
R
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.  
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.  
P
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.  
PARTITION – A portion of a hard disk  
devoted to a particular operating system and  
accessed as one logical volume by the system.  
PERFORMANCE– A measure of the speed  
of the drive during normal operation. Factors  
affecting performance are seek times, transfer  
rate and command overhead.  
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.  
PERIPHERAL– A device added to a system  
as an enhancement to the basic CPU, such as  
a disk drive, tape drive or printer.  
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.  
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 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.

Glossary  
REMOVABLE DISK – Generally said of  
disk drives where the disk itself is meant to be  
removed, and in particular of hard disks using  
disks mounted in cartridges. Their advantage  
is that multiple disks can be used to increase  
the amount of stored material, and that once  
removed, the disk can be stored away to  
prevent unauthorized use.  
SEEK – A movement of the disk read/write  
head in or out to a specific track.  
SERVO DATA – Magnetic markings  
written on the media that guide the  
read/write heads to the proper position.  
SERVO SURFACE – A separate surface  
containing only positioning and disk timing  
information but no data.  
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.  
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.  
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.  
SHOCK RATING – A rating (expressed in  
Gs) of how much shock a disk drive can  
sustain without damage.  
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.  
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.  
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.).  
SPINDLE – The center shaft of the disk  
upon which the drive’s platters are mounted.  
SPUTTER – A type of coating process used  
to apply the magnetic coating to some  
high-performance disks. In sputtering, the  
disks are placed in a vacuum chamber and the  
coating is vaporized and deposited on the  
disks. The resulting surface is hard, smooth,  
and capable of storing data at high density.  
Maxtor disk drives use sputtered thin film  
disks.  
S
SCSI – Acronym for Small Computer System  
Interface, an American National Standards  
Institute (ANSI) version of Shugart Associates'  
SASI interface between the computer and  
controller. SCSI has grown in popularity and  
is one of the most flexible and intelligent  
interfaces available.  
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.

Glossary  
SUBSTRATE – The material the disk  
U
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.  
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.  
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.  
V
T
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.  
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.  
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.  
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.  
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.  
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.
