Introduction
Maxtor Corporation
Maxtor Corporation has been providing high-quality computer storage products since 1982. Along the way,
we’ve seen many changes in data storage needs. Not long ago, only a handful of specific users needed more than
a couple hundred megabytes of storage. Today, downloading from the Internet and CD-ROMs, multimedia,
networking and advanced office applications are driving storage needs even higher. Even home PC applications
need capacities measured in gigabytes, not megabytes.
Products
Maxtor’s products meet those demanding storage capacity requirements with room to spare. They feature
proven compatibility and reliability. While DiamondMax™ 6800 is the latest addition to our family of high
performance 5,400 RPM desktop hard drives, DiamondMax™ 4320 series hard drives deliver industry-leading
capacity, performance and value for many PC applications.
Support
No matter which capacity, all Maxtor hard drives are supported by our commitment to total customer

DIAMONDMAX PLUS 5120 – INTRODUCTION
1 – 2
Conventions
If there is a conflict between text and tables, the table shall be accepted as being correct.
Key Words
The names of abbreviations, commands, fields and acronyms used as signal names are in all uppercase type
(e.g., IDENTIFY DRIVE). Fields containing only one bit are usually referred to as the “name” bit instead of
the “name” field.
Names of drive registers begin with a capital letter (e.g., Cylinder High register).
Numbering
Numbers that are not followed by a lowercase “b” or “h” are decimal values. Numbers that are followed by
a lowercase “b” (e.g., 01b) are binary values. Numbers that are followed by a lowercase “h” (e.g., 3Ah) are
hexadecimal values.
Signal Conventions
Signal names are shown in all uppercase type.
All signals are either high active or low active signals. A dash character (-) at the end of a signal name
indicates that the signal is low active. A low active signal is true when it is below ViL and is false when it is
above ViH. A signal without a dash at the end indicates that the signal is high active. A high active signal is
true when it is above ViH and is false when it is below ViL.
When a signal is asserted, it means the signal is driven by an active circuit to its true state.
When a signal is negated, it means the signal is driven by an active circuit to its false state.
When a signal is released, it means the signal is not actively driven to any state. Some signals have bias
circuitry that pull the signal to either a true or false state when no signal driver is actively asserting or negating
the signal. These instances are noted under the description of the signal.

Product Features
Functional / Interface
Maxtor DiamondMax™ 6800 hard drives contain all necessary mechanical and electronic parts to interpret control
signals and commands from an AT-compatible host computer. See Section 3 Product Specifications, for complete
drive specifications.
Zone Density Recording
The disk capacity is increased with bit density management – common with Zone Density Recording. Each
disk surface is divided into 16 circumferential zones. All tracks within a given zone contain a constant
number of data sectors. The number of data sectors per track varies in different zones; the outermost zone
contains the largest number of data sectors and the innermost contains the fewest.
Read/Write Multiple Mode
This mode is implemented per ANSI ATA/ATAPI-4 specification. Read/Write Multiple allows the host to
transfer a set number of sectors without an interrupt request between them, reducing transfer process
overhead and improving host performance.
UltraDMA - Mode 4
Maxtor DiamondMax 6800 hard drives fully comply with the new ANSI Ultra DMA protocol, which greatly
improves overall AT interface performance by significantly improving burst and sustained data throughput.
Multi-word DMA (EISA Type B) - Mode 2
Supports multi-word Direct Memory Access (DMA) EISA Type B mode transfers.
Sector Address Translation
All DiamondMax 6800 drives feature a universal translate mode. In an AT/EISA-class system, the drive may
be configured to any specified combination of cylinders, heads and sectors (within the range of the drive's
formatted capacity). DiamondMax 6800 drives power-up in a translate mode:

(*) The fields LZone (Landing Zone) and WPcom (Write Pre-comp) are not used by the Maxtor hard drive
and the values may be either 0 or the values set by the BIOS. All capacities listed in the above table are based
on 106or one million bytes.

PRODUCTDESCRIPTION
2 – 3
Logical Block Addressing
The Logical Block Address (LBA) mode can only be utilized in systems that support this form of translation.
The cylinder, head and sector geometry of the drive, as presented to the host, differs from the actual physical
geometry. The host AT computer may access a drive of set parameters: number of cylinders, heads and
sectors per track, plus cylinder, head and sector addresses. However, the drive can’t use these host parameters
directly because of zoned recording techniques. The drive translates the host parameters to a set of logical
internal addresses for data access.
The host drive geometry parameters are mapped into an LBA based on this formula:
LBA = (HSCA - 1) + HHDA x HSPT + HNHD x HSPT x HCYA (1)
= (HSCA - 1) + HSPT x (HHDA + HNHD x HCYA) (2)
where HSCA = Host Sector Address, HHDA = Host Head Address
HCYA = Host Cylinder Address, HNHD = Host Number of Heads
HSPT = Host Sectors per Track
The LBA is checked for violating the drive capacity. If it does not, the LBA is converted to physical drive
cylinder, head and sector values. The physical address is then used to access or store the data on the disk and
for other drive related operations.
Defect Management Zone (DMZ)
Each drive model has a fixed number of spare sectors per drive, all of which are located at the end of the
drive. Upon detection of a bad sector that has been reassigned, the next sequential sector is used.
For example, if sector 3 is flagged, data that would have been stored there is “pushed down” and recorded
in sector 4. Sector 4 then effectively becomes sector 3, as sequential sectors are “pushed down” across the
entire drive. The first spare sector makes up for the loss of sector 3, and so maintains the sequential order of
data. This push down method assures maximum performance.
On-the-Fly Hardware Error Correction Code (ECC)
5 symbols, single burst, guaranteed
Software ECC Correction
22 symbols, single burst, guaranteed
Automatic Park and Lock Operation
Immediately following power down, dynamic braking of the spinning disks delays momentarily allowing the
read/write heads to move to an inner mechanical stop. A small fixed magnet holds the rotary actuator in
place as the disk spins down. The rotary actuator is released only when power is again applied.

PRODUCTDESCRIPTION
2 – 4
Cache Management
Buffer Segmentation
The data buffer is organized into two segments: the data buffer and the micro controller scratch pad.
The data buffer is dynamically allocated for read and write data depending on the commands received.
A variable number of read and write buffers may exist at the same time.
Read-Ahead Mode
Normally, this mode is active. Following a read request, disk read-ahead begins on the first sector and
continues sequentially until the allocated buffer is full. If a read request is received during the read-ahead
operation, the buffer is examined to determine if the request is in the cache. If a cache hit occurs, read-
ahead mode continues without interruption and the host transfer begins immediately.
Automatic Write Reallocation (AWR)
This feature is part of the write cache and reduces the risk of data loss during deferred write operations. If a
disk error occurs during the disk write process, the disk task stops and the suspect sector is reallocated to a
pool of alternate sectors located at the end of the drive. Following reallocation, the disk write task continues
until it is complete.
Write Cache Stacking
Normally, this mode is active. Write cache mode accepts the host write data into the buffer until the buffer
is full or the host transfer is complete. A command complete interrupt is generated at the end of the transfer.
A disk write task begins to store the host data to disk. Host write commands continue to be accepted and
data transferred to the buffer until either the write command stack is full or the data buffer is full. The drive
may reorder write commands to optimize drive throughput.

PRODUCTDESCRIPTION
2 – 5
Major HDA Components
Drive Mechanism
A brush-less DC direct drive motor rotates the spindle at 5,400 RPM (±0.1%). The dynamically balanced
motor/spindle assembly ensures minimal mechanical run-out to the disks. A dynamic brake provides a fast
stop to the spindle motor upon power removal. The speed tolerance includes motor performance and motor
circuit tolerances.
Rotary Actuator
All DiamondMax™ 6800 drives employ a rotary voice coil actuator which consists of a moving coil, an
actuator arm assembly and stationary magnets. The actuator moves on a low-mass, low-friction center shaft.
The low friction contributes to fast access times and low power consumption.
Read/Write Electronics
An integrated circuit mounted within the sealed head disk assembly (near the read/write heads) provides up
to eight head selection (depending on the model), read pre-amplification and write drive circuitry.
Read/Write Heads and Media
Low mass, low force giant magneto-resistive read/write heads record data on 3.5-inch diameter disks. Maxtor
uses a sputtered thin film medium on all disks for DiamondMax 6800 drives.
Air Filtration System
All DiamondMax 6800 drives are assembled in a Class 100 controlled environment. Over the life of the drive,
a 0.1 micron filter and breather filter located within the sealed head disk assembly (HDA) maintain a clean
environment to the heads and disks. DiamondMax 6800 drives are designed to operate in a typical office
environment with minimum environmental control.
Microprocessor
The microprocessor controls the following functions for the drive electronics:
Command execution
Cache management
Data correction and error recovery
Diagnostic execution
Data sequencing
Head positioning (including error recovery)
Host interface
Index detection
Spin speed control

PCBA Jumper Location and Configuration
4092 Cylinder Limitation
On some older BIOS', primarily those that auto-configure the disk drive, a hang may occur when the drive
cylinder value exceeds 4096. The 4092 Cylinder Limitation jumper reduces the capacity in the Identify Drive to
4092 allowing large capacity drives to work with older BIOS'. A software driver is required to access the full
capacity of the drive.
Subsystem Configuration
Dual Drive Support
Two drives may be accessed via a common interface cable, using the same range of I/O addresses. The drives
are jumpered as device 0 or 1 (Master/Slave), and are selected by the drive select bit in the
Device/Head register of the task file.
All Task File registers are written in parallel to both drives. The interface processor on each drive decides
whether a command written to it should be executed; this depends on the type of command and which
drive is selected. Only the drive selected executes the command and activates the data bus in response to
host I/O reads; the drive not selected remains inactive.
A master/slave relationship exists between the two drives: device 0 is the master and device 1 the slave.
When J50 is closed (factory default, figure 2-1), the drive assumes the role of master; when open, the drive
acts as a slave. In single drive configurations, J50 must be closed.
Cable Select Option
CSEL (cable select) is an optional feature per ANSI ATA specification. Drives configured in a multiple drive
system are identified by CSEL’s value:
– If CSEL is grounded, then the drive address is 0.
– If CSEL is open, then the drive address is 1.
Jumper Location/Configuration
Darkened jumper pins indicate factory-installed (default) shunts.

Power Requirements
Power Mode Definitions
Spin-up
The drive is spinning up following initial application of power and has not yet reached full speed.
Seek
A random access operation by the disk drive.
Read/Write
Data is being read from or written to the drive.
Idle
The drive is spinning, the actuator is parked and powered off and all other circuitry is powered on.
The drive is capable of responding to read commands within 40 ms.
Standby
The spin motor is not spinning. The drive will leave this mode upon receipt of a command that requires
disk access. The time-out value for this mode is programmable. The buffer is active to accept write data.
Sleep
This is the lowest power state – with the interface set to inactive. A software or hardware reset is required
to return the drive to the Standby state.
EPA Energy Star Compliance
Maxtor Corporation supports the goals of the U.S. Environmental Protection Agency’s Energy Star program
to reduce the electrical power consumption of computer equipment.

< 1.0% Annual Return Rate (ARR) indicates the average against products
shipped. ARR includes all reasons for returns (failures, handling
damage, NDF), but does not include inventory credit returns.
Quality Acceptance Rate
< 500 DPPM The quality acceptance rate indicates the percentage of Maxtor
products successfully installed by our customers, and/or the number
of defective parts per million (DPPM) encountered during the entire
installation process.
Start/Stop Cycles
50,000 (minimum) This indicates the minimum cycles for reliable start/stop function at a
≥60% confidence level.
Data Reliability
< 1 per 1014 bits read Data errors (non-recoverable). Average data error rate allowed with all
error recovery features activated.
Component Design Life
5 years (minimum) Component design life is defined as a.) the time period before
identified wear-out mechanisms impact the failure rate, or b.) the time
period up to the wear-out point when useful component life expires.
