MaxtorCorporationhasbeenproviding high-qualitycomputerstorageproductssince
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.
Maxtor’s products meet the demanding data storage capacity requirements of today
and tomorrow. They are available in 5400- and 7200- RPM configurations with
capacity offerings from 10 to 80 GB and beyond.
The Maxtor D540X-4D family of drives is a 5400 RPM hard drive with capacities
from 30GB to 80GB.
No matter which capacity, all Maxtor hard drives are supported by our commitment
to total customer satisfaction and our No Quibble Service®guarantee. One call –or a
visit to our home page on the Internet (www.maxtor.com) –puts you in touch with
either technical support or customer service. We’ll provide you the information you
need quickly, accurately and in the form you prefer –a fax, a downloaded file
or a conversation with a representative.

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 signalis 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.

Maxtor hard disk drives are 1-inch high, 3.5-inch diameter random access storage
devices which incorporate an on-board Ultra ATA/100 interface controller. High
capacity is achieved by a balanced combination of high areal recording density and
the latest data encoding and servo techniques.
Maxtor's latestadvancements in electronic packaging and integration methods have
lowered the drive's power consumption and increased its reliability.
Exceptional data transfer rates, 5400 RPM spin speed and 12 ms access times make
these entry-class disk drives ideally-suited to desktop storage and consumer
electronics applications.

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.
$'!!'
This mode is implemented per ANSI ATA/ATAPI-6 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.

All Maxtor hard 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). Maxtor hard
drives power-up in a translate mode:

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 recordingtechniques. 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
= (HSCA - 1) + HSPT x (HHDA + HNHD x HCYA
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.
%' &3'&4
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, ifsector3 is flagged, data that would havebeen stored thereis “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 ofsector 3, and so maintains the sequential order of data. This
push down method assures maximum performance.

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.

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.
)5 '
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.
!! 34
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.
5 2
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.

A brushless DC direct drive motor rotates the spindle at 5400 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.
All Maxtor hard 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.

Two drives may be accessed via a common interface cable, using the same range of
I/O addresses. The drives have a jumper configuration 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 existsbetweenthe twodrives: device 0 is the master and
device 1 the slave. When the Master 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, the Master jumper must be closed.
!!
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.
