+------+------+------+--------------------------------------------+
X indicates the jumper setting does not matter.
Caution: The CS and DS jumpers should never be installed at the same
time.
DS Drive Select Jumper
-----------------------
You can also daisy-chain two drives on the IDE-bus Interface as
by using the DS (Drive Select) jumpers. If the DS jumper is
installed, the CS jumper must be removed (OPEN).
To configure a drive as the Master (Drive 0), a jumper must be
installed at the DS pins.
To configure a drive as the Slave (Drive 1), the DS jumper must be
removed.
NOTE
The order in which drives are connected in a daisy chain has no
significance.
CS Cable Select Jumper
-----------------------
When two Lightning 365/540/730A hard disk drives are daisy-chained
together, they can be configured as Master and Slave by using the CS
jumper or by using the DS jumper - BUT NOT BOTH at the same time. To
configure the drive as a Master or Slave with the CS feature, the CS
jumper is installed and the DS jumper is removed.
Once you install the CS jumper, the drive is configured as a Master
or Slave by the state of the Cable Select signal: pin 28 of the IDE
bus connector. Please not that pin 28 is a vendor-specific pin that
Quantum is using for a specific purpose. More than one function is
allocated to CS, according to the ATA CAM specification. If pin 28
is a 0 (grounded), the drive is configured as a Master. If it is a 1
(high), the drive is configured as a Slave. In order to configute two
drives in a Master/Slave relationship using the CS jumper, you need
to use a cable that provides the proper signal level at pin 28 of the
IDE bus connector.
SP Slave Present Jumper
------------------------
In combination with the current DS jumper settings, the Slave
Present jumper implements one of two possible configuratons:
When the drive is configured as a Master - that is, with the DS
jumper installed - the SP jumper should be installed on the Master
drive only if the Slave drive does not use the Drive Active/Slave
(DASP-) signal to indicate its presence.
When the drive is cnfigured as a Slave - that is, without the DS
jumper installed - the SP jumper enables the self-seek test. When
power is applied to the drive with the self-seek test enabled, the
drive executes seeks in a butterfly pattern.
If an error is encountered during the self-seek test, the test
terminates.
PO Product Option Jumper
------------------------
The PO jumper is reserved for use by specific customers. Do NOT
install the PO jumper for normal IDE master/slave operation.
J1A/B/C DC Power/Interface Connector
-------------------------------------
The drive's DC power can be applied to either section A or B.
The IDE-bus interface (40-pin) uses section C.

The mounting holes on the Lightning 365/540/730A hard disk drive
allow the drive to be mounted in any orientation.
Mounting
--------
Drive mounting orientation, clearance, and ventilation requirements
are described in the following subsections. For mounting, #6-32 UNC
screws are recommended.
Caution: The PCB is very close to the mounting holes. Do not
exceed the specified length for the mounting screws. The specified
screw length allows full use of the mounting-hole threads, while
avoiding damaging or placing unwanted stress on the PCB. To avoid
stripping the mounting-hole threads, the maximum torque applied to
the mounting screws must not exceed 8 inch-pounds.
Clearance
---------
Clearance from the drive - except mounting surfaces - to any surface
must be 0.05 inches minimum.
Ventilation
-----------
The Lightning 365/540/730AT hard disk drives operates without a
cooling fan, provided the ambient air temperature does not exceed
131*F (55*C).
DC Power (J1 A and B)
----------------------
The recommended mating connectors for the +5VDC and +12VDC input
power are listed above.
J1 A 4-Pin Connector: AMP P/N 1-480424-0
Loose piece contacts: AMP P/N VS 60619-4
Strip contacts: AMP P/N VS 61117-4
J1 B 3-Pin Connector: Molex P/N 5484 39-27-0032
Power can be supplied to either J1 section A or J1 section B.
Labels indicates the pin numbers on the connectors.
Power Sequencing
----------------
You may apply the power in any order or manner, or short or open
either the power or power return line with no loss of data or damage
to the disk drive. However, data may be lost in the sector being
written at the time of power loss. The drive can withstand transient
voltages of +10% to -100% from nominal while powering up or down.
LED Connector J2
----------------
The LED connector may be used to connect an external LED for the pur-
pose of monitoring drive activity. A 220-ohm resistor is connected in
series from the +LED pin to +5 volts. The -LED pin is connected to a
switching transistor on the drive that turns on and lights the LED
when the disk is performing a read or write operation. When no read
or write operation is taking place, the transistor turns off and the
LED is extinguished. The recommended mating connector parts are
following:
Two-position housing: Molex P/N 51021-0200
Loose-piece contacts: Molex P/N 50058-8100
Drive Cable and Connector
-------------------------
The hard disk drive connects to the host computer by means of a
cable. This cable contains a 40-pin connector that plug into the
drive, and a 40-pin connector that plugs into the host computer. At
the host end, the cable plugs into either an adapter board residing
in a host expansion slot or an on-board IDE adapter.
If two drives are connected by a cable with two 40-pin drive
connectors, the cable-select feature of the Lightning 365/540/730A
automatically configure each as drive 0 or drive 1 depending on the
configuration of pin 28 on the connector.
IDE-Bus Interface Connector (J1 C)
----------------------------------
On the Lightning 365/540/730A hard disk drive, the IDE-bus
interface cable connector (J1 section C) is a 40-pin Universal
Header.
To prevent the possibility of incorrect installation, has been keyed
by removing Pin 20, which ensures that a connector cannot be
installed upside down.
For Systems with a Motherboard IDE Adapter
==========================================
You can install the Lightning 365/540/730A hard disk drive in an
AT-compatible system that contains a 40-pin AT-bus connector on the
motherboard.
To connect the drive to the motherboard, use a 40-pin ribbon cable.
Ensure that pin 1 of the drive is connected to pin 1 of the mother-
board connector.
For Systems with an IDE Adapter Board
=====================================
To install a Lightning 365/540/730A hard disk drive in an
AT-compatible system without a 40-pin, AT-bus connector on its
motherboard, you need a third-party IDE-compatible adapter board.
Adapter Board Installation
--------------------------
Carefully read the manual that accompanies your adapter board before
installing it. Make sure that all the jumpers are set properly and
that there are no addressing or signal conflicts. You must also
investigate to see if your AT-compatible system contains a
combination floppy and hard disk controller board. If it does, you
must disable the hard disk drive controller functions on the
controller board before proceeding.
Once you have disabled the hard disk drive controller functions on
the floppy/hard drive controller, install the adapter board. Again,
make sure that you have set all jumper straps on the adapter board
to avoid addressing and signal conflicts.
Connecting the Adapter Board and the Drive
------------------------------------------
Use a 40-pin ribbon cable to connect the drive to the board.
1. Insert the 40-pin cable connector into the mating connector on
the adapter board. Make sure that pin 1 of the connector matches
with pin 1 on the cable.
2. Insert the other end of the cable into the header on the drive.
When inserting this end of the cable, make sure that pin 1 of
the cable connects to pin 1 of the drive connector.
3. Secure the drive to the system chassis by using the mounting
screws.
Base Casting Assembly
---------------------
A single-piece aluminium-alloy base casting provides a mounting sur-
face for the drive mechanism and PCB. The base casting also acts as
the flange for the DC motor assembly. To provide a contamination-free
environment for the HDA, a gasket provides a seal between the base
casting and the metal cover that enclose the drive mechanism.
Air Filtration
--------------
The Lightning 365/540/730A hard disk drives are Winchester-type
drives. The heads fly very close to the media surface. Therefore, it
is essential that the air circulating within the drive be kept free
of particles. Quantum assembles the drive in a Class-100, purified
air environment, then seals the drive with a metal cover. When the
drive is in use, the rotation of the disk forces the air inside of
the drive through an internal filter.
DC Motor Assembly
-----------------
Integral with the base casting, the DC motor assembly is a fixed-
shaft, brushless DC spindle motor that drives the counter-clockwise
rotation of the disks.
Electrical Characteristics
--------------------------
All signals are transistor-transistor logic (TTL) compatible - with
logic 1 greater than 2.0 volts and less than 5.25 volts; and logic 0
greater than 0.0 volts and less than 0.8 volts. Neither the adapter
board, motherboard interface, or drives require terminating
resistors.

QUANTUM LIGHTNING 365/540/730AT PRODUCT MANUAL 81-106892-01
General Description
-------------------
Quantum's Lightning 365/540/730AT hard disk drives are a part of a
family of high-performance, 1-inch-high hard disk drives manufactured
to meet the highest product quality standards.
Lightning hard disk drives use nonremovable, 3 -inch hard disks, and
are available with a Small Computer System Interface (SCSI) or
Advanced Technology (AT) interface.
The Lightning 365/540/730AT hard disk drives feature an embedded AT
drive controller and use AT commands to optimize systems performance.
Because the drive manages media defects and error recovery
internally, these operations are fully transparent to the user.
System Startup and Operation
----------------------------
Once you have installed the Lightning 365/540/730A hard disk drive
and adapter board (if required) in the host system, you are ready to
partition and format the drive for operation. To set up the drive
correctly, follow these steps:
1. Power on the system
2. Run the SETUP program. This is generally on a Diagnostics or
Utilities disk, or within the system's BIOS.
3. Enter the appropriate parameters.
The SETUP program allows you to enter the types of optional hard-
ware installed - such as the hard disk drive type, the floppy disk
drive capacity, and the display adapter type. The system's BIOS
uses this information to initialize the system when the power is
switched on. For instructions on how to use the SETUP program,
refer to the system manual for your PC.
During the AT system CMOS setup, you must enter the drive type for
the Lightning 365/540/730A hard disk drive. The drive supports the
translation of its physical drive geometry parameters such as
cylinders, heads, and sectors per track, to a logical addressing
mode. The drive can work with different BIOS drive-type tables of
the various host systems.
4. Boot the system using the operating system installation disk.
NOTE
The drive is shipped from the factory with a low-level format. A low-
level format is not required.
Formatted Capacity
------------------
At the factory, the Lightning 365/540/730A receives a low-level
format that creates the actual tracks and sectors on the drive.
Data Transfer Rates
-------------------
Data is transferred from the disk to the read buffer at a rate up to
5.9 MB/s (47.2 Mbits/s) in burst. Data is transferred from the read
buffer to the IDE bus at a rate up to 6.0 MB/s, using programmed I/O
without IORDY, up to 11.1 MB/s using programmed I/O with IORDY, or at
a rate of up to 13.3 MB/sec using multi-word DMA.
Reliability
-----------
Mean Time Between Failures (MTBF): 150,000 Power On Hours (POH),
typical usage
Component Life: 5 years
Preventive Maintenance (PM): Not required
Start/Stop: 20,000 cycles (minimum)
The Quantum MTBF numbers represent Bell-Core TR-TSY-000332 MTBF
predictions and represent the minimum MTBF that Quantum or a
customer would expect from the drive.
Error Detection and Correction
------------------------------
As disk drive areal densities increase, obtaining extremely low error
rate requires a new generation of soghisticated error-correction
codes. Quantum Lightning 365/540/730A series hard disk drives
implement 112-bit single- and double-burst Reed-Solomon error
correction techniques to reduce the uncorrectable read error rate to
less than one bit in 1 x 10(14) bits read.
When errors occur, an automatic retry and a more rigorous double-
burst correction algorithm enable the correction of any sector with
two burst of three incorrect bytes each or up to six multiple random
one-byte burst errors. In addition to these advanced error correction
capabilities, the drive's additional cross-checking code and
algorithm double checks the main ECC correction to greatly reduce the
probability of miscorrection.
Automatic Actuator Lock
-----------------------
To ensure data integrity and prevent damage during shipment, all
Lightning Series hard disk drives feature a dedicated landing zone
and Quantum's patented AIRLOCK. AIRLOCK, locks the headstack in the
landing zone. It consists of an airvane mounted near the perimeter of
the disk stack and a locking arm that restrains the actuator arm
assembly.
When DC power is applied to the motor and the disk stack rotates, the
rotation generates an airflow on the surface of the disk. As the flow
of air across the airvane increases with disk ratation, the locking
arm pivots away from the actuator arm, enabling the headstack to move
out of the landing zone. When DC power is removed from the motor, a
return mechanism automatically pulls the actuator into the landing
zone, where the AIRLOCK holds it in place.
Disk Caching
------------
The Lightning 365/540/730A hard disk drive incorporates DisCache, a
96K disk cache, to enhance drive performance. This integrated feature
is user-programmable and can significantly improve system throughput.
Read and write caching can be enabled or disabled by using the SET
CONIGURATION command.
Defect Management
------------------
The Lightning 365AT allocate one sector per cylinder as a spare, and
the Lightning 730AT allocates two sectors per cylinder as spares. In
the factory, the media is scanned for defects. If a sector on a
cylinder is found to be defective, the address of the sector is added
to the drive's defect list. Sectors located physically subsequent
to the defective sector are assigned logical block addresses such
that a sequential ordering of logical blocks maintained. This inline
sparing technique is employed in an attempt to eliminate slow data
transfer that would result from a single defective sector on a
cylinder.
If more than one sector is found defective on a cylinder, the inline
sparing technique is applied to the first sector only. The remaining
defective sectors are replaced with the nearest available spare
sectors on nearby cylinders. Such an assignment of additional re-
placement sectors from nearby sectors rather than having a central
pool of spare sectors is an attempt to minimize the motion of the
actuator and head that otherwise would be needed to find a replace-
ment sector. The result is minimal reduction of data throughput.
