The drive will operate in all axis (6 directions).
Recommended Mounting Configuration
----------------------------------
Maxtor 7000 Series drive design allows greater shock tolerance than
that afforded by larger, heavier drives. The drive may be mounted in
any attitude using four size 6-32 screws with 1/8" maximum
penetration and a maximum torque of 5-inch pounds.
Allow adequate ventilation to the drive to ensure reliable drive
operation.
Air Filtration System
---------------------
All 7000 Series drives are designed to operate in a typical
office environment with minimal environmental control. Over the life
of the drive, a 0.3 micron filter and breather filter (located within
the HDA) maintain a clean environment to the heads and disks.
Read/Write Electronics
----------------------
An integrated circuit mounted within the sealed enclosure (near the
read/write heads) provides one of four head selection (depending on
the model), read preamplification, and write drive circuitry.
Read/Write Heads and Disks
--------------------------
Low mass, low force read/write heads record data on two 3.5"
diameter disks. Maxtor uses a sputtered thin film medium on all
disks for 7000 Series drives.
Drive Mechanism
---------------
A brushless DC direct-drive motor rotates the spindle at 4,480 RPM
( 0.1%). The dynamically balanced motor/spindle assembly ensures
minimal mechanical runout 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.
Voice Coil Actuator
-------------------
All 7000 Series drives employ a rotary voice coil actuator which
consists of a moving coil, an E-block or actuator arm assembly, and
stationary magnets. The actuator moves on a low-mass, low-friction
center shaft. The low friction generated contributes to fast average
access time and low power consumption.
Automatic Headpark and Lock Operation
-------------------------------------
Immediately following power-down, dynamic braking of the spinning
disks delays momentarily and lets the heads move to an inner
mechanical stop. A small fixed magnet holds the heads in place as the
disk spin down. The heads are released only when power is again
applied.
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 drive 0 or 1,
and are selected by the drive select bit in the Drive/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: drive 0 is
the master, and drive 1, the slave. When J20 is closed (factory
default), the drive assumes the role of master; when open, the drive
acts as a slave. In single drive configurations, J20 must be closed.
Cable Select
------------
CSEL (cable select) is an optional feature per ATA CAM 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.
NOTE
If the Cable Select jumper (J24) is installed, the Master/Slave
jumper (J20) will be ignored.
Sector Address Translation
--------------------------
All 7000 Series drives feature a Universal Translate Mode. In an
AT-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).
These drives powers-up in the Translate Mode:
Model |Cylinders |Heads |Sectors
----------+----------+------+-------
71050A | 2045 | 16 | 63
----------+----------+------+-------
71626A/AP | 3158 | 16 | 63
----------+----------+------+-------
71260A/AP | 2448 | 16 | 63
----------+----------+------+-------
71084A/AP | 2105 | 16 | 63
----------+----------+------+-------
7541A/AP | 1052 | 16 | 63
Interface Connector
-------------------
All 7000 Series AT drives have a 40-pin interface connector mounted
on the PCBA. The drive may connect directly to the host; or it can
also accommodate a cable connection (maximum cable length: 18
inches).
(Striped Edge = Pin 1)
Buffer Segmentation
-------------------
The data buffer is organized into three segments: the read buffer,
the write buffer, and an micro controller scratch pad. The read
segment occupies half of the buffer and operates as a circular read-
ahead buffer. The write segment occupies the other half. During write
operations, it contains the host write data. Commands ATA Read Buffer
(E4) and ATA Write Buffer (E8) are implemented per CAM specification
4a.
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
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.

Introduction
------------
Maxtor 7000 Series AT disk drives are 1" high, 3.5" random access
storage devices which incorporate an on-board AT controller. Maxtor
engineers have applied recent advances in hard drive technology to
the design and manufacture of these drives. High data transfer rates
and fast access times make them especially well-suited to desktop and
workstation applications.
Defect Management Zone (DMZ)
----------------------------
Each drive model has a fixed number of spare sectors per DMZ:
71626A/AP = 6,
71260A/AP = 5,
71084A/AP = 4 and
7541A/AP = 2
all of which are located at the end of each DMZ. Upon detection of a
bad sector that has been reassigned, the next sequential sector is
used.
The first spare sector makes up for the loss of sector 3, and so
maintains the sequential order of data, with 3 spare sectors still
allocated for that cylinder. This push down method assures maximum
performance.
In the rare occurrence that the number of reassigned bad sectors
exceed the number of spare sectors allocated for that cylinder, an
alternate track area in Zone 6 of the disk is used. All models
have five (5) alternate tracks per surface.
Error Correction Code
---------------------
On-the-fly Hardware ECC
-----------------------
41 bits, single burst, guaranteed
17 bits, double burst, guaranteed
Software ECC Correction
-----------------------
113 bits, single burst, guaranteed
17 bits, five burst, guaranteed
Zone Density Recording
----------------------
The disk capacity is increased with bit density management - common
with Zone Density Recording. Each disk surface is divided into 10
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.
Execute Drive Diagnostics
-------------------------
Commands the drive to implements the internal diagnostics tests.
(These tests are executed only upon command receipt; they do not run
automatically at power up or after a reset.)
The drive sets BSY immediately upon receiving this command.
This table presents the codes and their descriptions:
Note that the value in the Error register should be viewed as a
unique 8 bit Code.
+-----------+----------------------------------+
|Error Code | Description |
+-----------+----------------------------------+
| 01 | no error detected |
+-----------+----------------------------------+
| 02 | formatter device error |
+-----------+----------------------------------+
| 03 | sector buffer error |
+-----------+----------------------------------+
| 04 | ECC circuitry error |
+-----------+----------------------------------+
| 05 | controller microprocessor error |
+-----------+----------------------------------+
| 8x | slave drive failed (Note) |
+-----------+----------------------------------+
Note: If a slave drive fails diagnostics, the master
drive OR's 80 hex with its own status, and loads that
code into the Error register.
If a slave drive passes diagnostics (or a slave is
absent), the master drive OR's 00 with its own status
and loads that code into the Error register.
EISA Type "B" and Type "F" DMA Modes
------------------------------------
Direct Memory Access (DMA) transfers improves system performance by
significantly improving troughtput.
Physical Configuration Sectors per track
----------------------------------------
Zone 1 = 156 Zone 2 = 154 Zone 3 = 150
Zone 4 = 140 Zone 5 = 132 Zone 6 = 126
Zone 7 = 120 Zone 8 = 108 Zone 9 = 100
Zone 10 = 90
Data transfer rate (MBytes per second)
--------------------------------------
To from media
Zone 01 = 8.10 Zone 06 = 6.50
Zone 02 = 8.02 Zone 07 = 5.94
Zone 03 = 7.68 Zone 08 = 5.55
Zone 04 = 7.18 Zone 09 = 5.08
Zone 05 = 6.80 Zone 10 = 4.61
Logical Block Addressing
------------------------
The Logical Block Address (LBA) mode can only be utilized into
systems that support this form of translation. The cylinder, head and
sector geometry of the drive, as presented to the host, differs from
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)+HHDAxHSPT+HNHDxHSPTxHCYA (1)
= (HSCA-1)+HSPTx(HHDA+HNHDxHCYA) (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 the data stored
on the disk and other drive related operations.
Installation Steps
------------------
Warning!
Pre-loaded Software on Drive
This Maxtor hard drive is factory configured with a 112MB partition
containing Max Blast Disk Manager installation software by Ontrack
Systems. Please leave this partition intact until you choose the
appropriate installation option.
As a precautionary measure, Maxtor recommendeds that you download a
copy of the MaxBlast software to a blank diskette even if you choose
an alternate high-level formatting method.
Install a 40-pin ribbon connector. The striped edge of this cable
represents pin 1 and must be oriented towards pin 1 at the drive
connector and at the host connector.
Install a DC power connector...
If AT BIOS supports user programmable parameters, program System BIOS
with one of these default Parameters.
Model Cylinders Heads Sectors Capacity
71262AP 3158 16 63 1,626 MB
71260AP 2632 16 63 1,260 MB
71084AP 2105 16 63 1,084 MB
7813AP 1579 16 63 813 MB
7541AP 1052 16 63 541 MB
If AT
BIOS does not support programmable drive type, choose parameters that
closely match, but do not exceed, the drive's formatted capacity.
The drive is now ready for partitioning and high-level formatting
with any operating system. For example:
Partition the drive using the FDISK command from MS-DOS
version 3.3 of higher.
High level format the drive using the FORMAT command from
MS-DOS version 3.3 or higher.
Secure the drive in a suitable drive bay with 6-32 x 1/4" screws.
NOTE
WPC and Landing Zone BIOS entries do not need a specific number for
proper operation. Maxtor AT interface hard drives will ignore and
override any numbers programmed.
