Jumper setting
==============
x = Jumper set at factory
J301 Terminator Power Selection
-------------------------------
Terminator power generation may occur internally from the disk drive
(when J301 is jumpered), or externally from the SCSI bus. Factory
default is J301 jumpered.
J302 Drive Power-Up Option
---------------------------
Pin 1-2 OPEN Wait for Start Command - The disk drive will not
spin-up until the initiator issues a START/STOP
UNIT command with the start bit equal to one.
CLOSED Start When Power Applied - The spin motor starts
when power is supplied.
J303 Parity Disable Option
----------------------------
The parity disable jumper, J303, enables (open, factory default) or
disables (jumperred) odd parity detection in the disk drive.

When jumpered, the corresponding bit is a 1.
The SCSI bus supports connection of up to seven devices, but
communication can occur only between two SCSI devices at a time. Each
device has an assigned ID bit that establishes device priority on the
SCSI bus. When two SCSI devices communicate, one acts as an initiator
and the other as a target. The initiator orginates an operation and
the target performs the operation specified by the initiator. An
initiator can address up to seven other logical units (LUNs) attached
to one target. The drive has only one logical unit attached. (LUN=0).

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. Use size 6-32 screws with 1/8" maximum penetration.
Allow adequate ventilation to the drive to ensure reliable operation
over the operating temperature range.
Interface Termination
---------------------
SCSI devices require proper interface termination. On a SCSI bus
daisy chain, terminate only the first and last device. All devices
between the first and last devices must have their terminators
removed. As shipped, the interface signal lines are terminated with
two removable 220/330 ohm resistor network packs.
A dot on the terminator (RP301-RP302) indicates the position of pin
1; pin 1 is also identified as the terminator pin farthest from power
connector. For the drive to function correctly, orient each
terminator pack with its identifying pin 1 dot facing the direction
opposite the power connector.
Any device driving the disk inputs should be of the open collector
type, capable of sinking at least 48 mA at a voltage level less than
0.5 V DC (7438 or equivalent).
Devices receiving 7000 Series disk drive outputs should be SCHMITT
trigger type (74LS14, 74LS240, or equivalent) to improve noise
immunity. The initiator should not load the bus with more than one
standard low-power Schotky transistor-transistor logic (LSTTL) input
load per line. The initiator should terminate all signals with
220/330 ohm terminators.
Buffering Scheme
----------------
The drive has a 64K circular First-In-First-Out (FIFO) buffer. The
buffer controller allows simultaneous transfer either:
1.) to the drive from the initiator, or
2.) from the drive to the initiator.
64K Data Buffer and Look-Ahead Cache
------------------------------------
The target device anticipates sequential reads by reading to fill the
buffer, making data immediately available to new READ commands. By
temporarily placing small amounts of data in high-speed memory, cache
with look-ahead read decreases access time to sequential data in the
drive. Read-ahead performs all the required seeks and head switching
needed to fill the buffer with sequential data.
Power Connector
---------------
Power is applied through a 4-pin AMP connector (recommended mating
connector: AMP PN 1-480424-0, using AMP pins PN 350078-4). This power
connector conforms to the industry-standard 4-pin power connector.
Note: DO NOT connect data cable or power cable to drive with power
on.
Electrical Interface
--------------------
SCSI uses single-ended drivers and receivers which allow a maximum
cable length of 22 feet (6 meters) from the first to the last
device (up to 7 devices) on the bus. The drive interfaces to the
SCSI host via a 50-pin keyed ribbon cable; Maxtor recommends the 3M
PN 3425-3000 cable connector.
All assigned signals are terminated with 220 ohms to +5 volts and 330 ohms to ground at each end of the cable. SCSI requires removal of the two terminator networks on the drive when the drive is between terminated devices on a SCSI daisy chain. Terminators are fragile: remove them carefully and save for later use.
All signals driven by the drive are open collector and have the
output characteristics as follows.
Signal True 0.0 V DC to 0.8 V DC
Maximum Total Input Load -0.4 mA @ 0.4 V DC
Signal False 2.5 to 5.25 V DC
Minimum Input Hyteresis 0.2 V DC
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
--------------------------
Two or four low-mass, low-force minicomposite metal-in-GAP (MIG)
read/write heads record data on the 3.5" diameter disk(s). Maxtor
uses a sputterred thin-film media on all disks for 7000 Series
drives.
Drive Meachanism
----------------
A brushless DC direct-drive motor rotates the spindle at 3,551 RPM
( 0.1%).
The dynamically balanced motor/spindle assembly ensures minimal
mechanical runout of the disk(s). 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
-------------------
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
---------------------------
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 release only upon reapplication of power.
Acoustic Noise
--------------
Measurements made in idle (spinning) on-track mode.
1 meter perpendicular to top cover 35 dBA (typical)

Features
MAXTOR 7213S PRODUCT MANUAL PART 1224 REV. P3
Multi-Initiator Support
-----------------------
The drive provides full multi-initiator support with command queuing
for up to seven initiators. The target device can accept up to six
commands (one from each remaining initiator) while processing a
command from a seventh initiator.
How Look-Ahead Cache Functions
------------------------------
In the absense of an error, corrected data, or an interrupt command,
the drive caches not only requested sectors, but "look ahead" and
caches data from the sector that follow. (Look-ahead cache reads
across track boundaries.) The look-ahead feature prepares the drive
to transfer cahed data when the host request it, and so prevents
access time delays.
Caching of sectors continues until:
1.) an error occurs,
2.) a host command inconsistent with sequential reads is received.
Commands are interrupt driven: if the drive is performing a look-
ahead cache when a command is received, it will stop the cache and
process the command. Consequently, look-ahead cache operations do
not ass overhead ro command processing.
RESETs and WRITE or WRITE LONG commands to any of the cached sectors
invalidate the whole cache.
Defect Management
-----------------
REASSIGN commands push data down within the cylinder to maintain
sequential order and assure maximum performance.
The 7213S has four spare sectors per cylinder; They are located at
the end of each cylinder.
Upon detection of an error in a sector, execution of a REASSIGN
command flags that sector as bad; the next sequential sector is then
used.
Data Encoder/Decoder
--------------------
The data encoder/decoder, a single semi-custom integrated circuit,
employs an RLL encoding scheme and provides all clocking necessary
for synchronization. This circuit interfaces to the data sequencer
and either encodes or decodes serial data to or from the HDA.
Power-Up Sequence ----------------- DC power (+5V and +12V) may be supplied in any order. Both power supplies must be present and within the tolerances of the power sensing circuit before the spin motor will operate. Once power is applied, the actuator lock automatically disengages. The drive then performs a recalibration sequence to track zero, spins up, and becomes ready in 10 sceonds. The drive executes its recalibration sequence whenever power is applied or the SCSI START/STOP command is invoked via the SCSI bus.
Regulatory Compliance
---------------------
Maxtor 7000 Series drives comply with relevant product safety
standards such as UL, CSA, VDE and TUV rules and regulations. As
delivered, 7000 Series drives are designed for integration before
use. They are Class B computing devices built in compliance with
FCC rules and regulations, Part 15, Subpart J, governing the EMI of
computing devices.
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 communicaions.
General
MAXTOR SCSI INSTALLATION
GENERIC INSTALLATION PROCEDURE FOR A SCSI DRIVE
-----------------------------------------------------------
1. Install a 50 pin ribbon connector making sure pin 1, which
can be identified by the striped edge of the cable, is closest
to the power connector on the drive.
2. Install a DC power cable to the back of the drive.
3. Verify the SCSI ID selection.
Note: SCSI ID usually needs to be set to 0 to be the boot drive.
The last physical device on the SCSI bus must be terminated.
Any other drive or SCSI device connected between the host and
the device at the end of the bus must not be terminated.
4. Apply power to the computer.
4a. When memory test is complete go into your system's Standard
C-MOS set-up.
(Note: There are various ways to get into C-MOS set-up,
please refer to system's manual for instuctions.)
4b. Set the drive type to "Not Installed". This intelligent drive
will identify itself to the SCSI host adapter.
5. Boot from a DOS diskette that has FDISK.EXE and FORMAT.COM on
it. At the A> prompt type in FDISK. At the menu options select
option 1 to create a DOS partition. Another menu will appear and
from those options choose 1 to create a Primary DOS partition.
Select yes to make 1 large partition and it will automatically
become active. Then escape from FDISK.
6. At the A> prompt type in FORMAT C:/S
This does a high-level format on the drive and transfers the
system files in order for the drive to be bootable.
(Note: Maxtor SCSI drives are low-level formatted at the factory)
7. The drive is now bootable. As a test remove the DOS diskette
from A and press reset to re-boot the computer, a C> should be
displayed, the drive is now ready for operation.
