DIAMONDMAX VL 30 – INTRODUCTION
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 DESCRIPTION
Product Features
Functional / Interface
Maxtor DiamondMax VL 30 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-5 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 VL 30 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 VL 30 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 VL 30 drives power-up in a translate mode:
MODEL CYL HD SPT LZone WPcom MAX LBA CAPACITY

(*) 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
6
or one million bytes.
on 10
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:
2 – 2
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
PRODUCT DESCRIPTION
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)
16 symbols, single burst, guaranteed.
Software ECC Correction
24 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.
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, readahead 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.

PRODUCT DESCRIPTION
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 VL 30 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 VL 30 drives.
Air Filtration System
All DiamondMax VL 30 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 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

PRODUCT DESCRIPTION
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.

Cylinder Limitation Jumper Description
On some older BIOS', primarily those that auto-configure the disk drive, a hang may occur. The Cylinder
Limitation jumper reduces the capacity in the Identify Drive allowing large capacity drives to work with older
BIOS'. The capacity reported when J46 is closed will be as follows: drives less than or equal to 32GB will
report 2.1GB. Drives greater than 32GB will report 32GB.

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.

EMC/EMI
Radiated Electromagnetic Field Emissions - EMC Compliance
The hard disk drive mechanism is designed as a subassembly for installation into a suitable enclosure and is
therefore not subject to 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.
Canadian Emissions Statement
This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus as set
out in the radio interference regulations of the Canadian department of communications.
Le present appareil numerique n'emet pas de bruit radioelectriques depassant les limites applicables aux
appareils numeriques de Class B prescrites dans le reglement sur le brouillage radioelectrique edicte par le
ministere des communications du Canada.
Safety Regulatory Compliance
All Maxtor hard drives comply with relevant product safety standards such as CE, CUL, TUV and UL rules and
regulations. As delivered, Maxtor hard drives are designed for system integration before they are used.
