NOTE
In the table below, a 0 indicates that the jumper is removed, a 1
indicates that the jumper is installed, and an X indicates that the
jumper setting does not matter.
CS Cable Select Jumper
-----------------------
When two Fireball 540/1080AT 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 jumpers. To configure the drive as a
Master or Slave with the CS feature, the CS jumper is installed.
Once you install the CS jumper, the drive is configured as a Master
or Slave by state of the Cable Select signal, which is pin 28 at the
IDE-bus interface connector. Please note 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 specifica-
tion. If pin 28 is 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
configure two drives in a Master/Slave realationship using the CS
jumper, you need to use a cable that provides the proper signal
level at pin 28 of the IDE bus connector. This allows two drives to
operate in a Master/Slave realtionship according the drive cable
placement.
Drive Select Jumper
-------------------
You can also daisy-chain two drives on the IDE bus interface by using
their Drive Select (DS) jumpers. To use the DS feature, the CS jumper
must be removed.
To configure a drive as the Master (Drive 0), a jumper must be
installed on the DS pins.
The Quantum Fireball 540/1080AT hard disk drives are shipped from the
factory as a Master (Drive 0 - DS jumper installed). To configure a
drive as a Slave (Drive 1), the DS jumper must be removed. In this
configuration, the spare jumper removed from the DS position may be
stored on the SP jumper pins.
NOTE
The order in which drives are connected in a daisy chain has no
significance.
Slave Present Jumper (SP)
-------------------------
In combination with the current DS or CS jumper settings, the Slave
Present (SP) jumper implements one of two possible configurations:
- When the drive is configured as a Master (DS jumper installed or
CS jumper installed and the Cable Select signal set to 0) the SP
jumper indicates to the drive that a slave is present. The SP
jumper should be installed on the Master drive only if the Slave
drive does not use the Drive Active/Slave Present (DASP-) signal
to indicate its presence.
- When the drive is configured as a Slave (DS jumper not installed)
the SP jumper position is used to store the DS jumper and will
have no effect.
If an error is encountered during the self-seek test, the test
terminates.
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.

Orientation
-----------
The mounting holes on the Quantum Fireball 540/1080AT hard disk drive
allow the drive to be mounted in any orientation.
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. A maximum screw
length of 0.25 inches may be used on the side mounting locations
when a bracket of 0.040 inches minimum thickness is included.
IDE BUS ADAPTER
---------------
There are two ways you can configure a system to allow the Quantum
Fireball 540/1080AT hard disk drive to communicate over the IDE bus
of an IBM or IBM-compatible PC:
1. Connect the drive to a 40-pin IDE bus connector (if available) on
the motherboard of the PC.
2. Install an IDE-compatible adapter board in the PC and connect the
drive to the adapter board.
40-Pin IDE Bus Connector
------------------------
Many of the later design PC motherboards have a built-in 40-pin IDE
bus connector that is compatible with the 40-pin IDE interface of the
Quantum Fireball 540/1080AT hard disk drive. If the motherboard has
an IDE connector, simply connect a 40-pin ribbon cable between the
drive and the motherboard.
Adapter Board
-------------
If your PC motherboard does not contain a built-in, 40-pin IDE bus
interface connector, you must install an IDE bus adapter board and
connecting cable to allow the drive to interface with the mother-
board. Quantum does not supply such an adapter board, but they are
available from several third-party vendors.
Clearance
---------
Clearance from the drive - except mounting surfaces - to any surface
must be 0.05 inches (1.25 mm) minimum.
Ventilation
-----------
The Quantum Fireball 540/1080AT 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.
IDE-Bus Interface Connector (J1 C)
----------------------------------
On the Fireball 540/1080AT 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 Fireball 540/1080AT 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
18 inches in length or shorter. Ensure that pin 1 of the drive is
connected to pin 1 of the motherboard connector.
For Systems with an IDE Adapter Board
=====================================
To install a Fireball 540/1080AT hard disk drive in an
AT-compatible system without a 40-pin, IDE 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 Fireball 540/1080AT 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.
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 Fireball 540/1080AT
automatically configure each as drive 0 or drive 1 depending on the
configuration of pin 28 on the connector.

QUANTUM FIREBALL 540/1080AT PRODUCT MANUAL 81-109318-02 8/1995
General Description
-------------------
Quantum's Fireball 540/1080AT 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.
These hard disk drives use nonremovable, 3 -inch hard disks, and
are available with a Small Computer System Interface (SCSI-2, 3) or
Advanced Technology (ATA) interface.
The Fireball 540/1080 AT hard disk drives feature an embedded hard
disk drive controller and use ATA 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 Fireball 540/1080 AT 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 Fireball 540/1080 AT 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.
Formatted Capacity
------------------
At the factory, the Fireball 540/1080 AT 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
10.5 MB/s (84 Mbits/s) in bursts. Data is transferred from the read
buffer to the IDE bus at a rate up to 6.67 MB/s, using programmed I/O
without IORDY, or at a rate of up to 16.67 MB/s using programmed I/O
with IORDY, or at a rate of up to 16.67 MB/sec using multi-word DMA.
Reliability
-----------
Mean Time Between Failures (MTBF): 500,000 Power On Hours (POH),
typical usage
Component Life: 5 years
Preventive Maintenance (PM): Not required
Start/Stop: 40,000 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 Fireball 540/1080 AT series hard disk drives
implement 160-bit triple-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 Fireball 540/1080 AT hard disk drive incorporates DisCache, a
80K 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 Fireball 540/1080 AT allocate one sector per cylinder as a spare.
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 sub-
sequent 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.

QUANTUM ATA TIPS
Comparing the Fast ATA and Enhanced IDE Disk Drive Interfaces
-------------------------------------------------------------
Why are Fast ATA and Fast ATA-2 Important?
Faster data transfer rates are important because a computer is
only as fast as its slowest component. Today's 486, Pentium, and
PowerPC-based computers offer processor speeds many times faster
than only two years ago. Bus speeds have also increased with the
inclusion of 32-bit VL and PCI local buses, which have a maximum
data transfer rate of 132 MB/second.
Faster buses mean that data can be transferred from the storage
device to the host at greater speeds. Fast ATA and Fast ATA-2 allow
disk drives to store and access this data faster, thus enhancing the
other high-speed components in the system and removing the
bottleneck associated with older ATA/IDE drives. In short, Fast
ATA helps bring very high performance to desktop PC systems.
In addition, when compared to SCSI, Fast ATA is the least expensive
way to achieve faster disk drive data transfer rates and higher
system performance. The implementation of Fast ATA through system
BIOS provides performance without incremental hardware co sts.
Older systems can support Fast ATA using an inexpensive host
adapter.
Fast ATA and Fast ATA-2 are easy to implement in either VL or PCI
local bus systems. The hardware connection can be made using a
standard 40-pin ATA ribbon cable from the drive to the host
adapter. Direct connection to the motherboard further eases
integration when provided by the motherboard supplier.
Once connected, the high data transfer capabilities of Fast ATA can
be enabled through the data transfer options found in most CMOS BIOS
setup tables. Newer versions of BIOS provide automatic configuration
for Fast ATA drives.
Fast ATA can improve efficiency by allowing more work to be
completed in less time because the computer moves data faster.
Graphic, multimedia, and audio/visual software users will benefit
most because the speed of those applications, which work with large
blocks of data, are transfer-rate dependent.
The Fast ATA and Enhanced IDE interfaces both use the local bus to
speed data transfer rates. Enhanced IDE also uses the same PIO modes
as Fast ATA, although a data transfer rate equal to the PIO mode 4
rate has not been announced for Enhanced IDE. The major differences
between Fast ATA and Enhanced IDE are that the latter includes
three distinct features in addition to fast data transfer rates.
The additional features of Enhanced IDE are as follows:
High-capacity addressing of ATA hard drives over 528 MB -
a BIOS and device driver function.
Dual ATA host adapters supporting up to four hard disk drives per
computer system - a function of BIOS, operating system, and host
adapter, not the drive.
Support for non-hard disk drive peripherals such as CD-ROMs -
a function of BIOS and the operating system, not the drive
Each of these features supports improved functionality at a system
level, a positive development for the industry and end users.
However, support for all three features requires an extremely high
degree of integration and revisions to operating systems and hard-
ware, in addition to BIOS changes. Specific support is required not
only for the storage peripherals but also for host adapters, core
logic, the system bus, BIOS, and operating systems - virtually every
major block of PC architecture.
There is no central industry-supported standard that controls the
features of Enhanced IDE. With no standard, some products sold as
"Enhanced" may provide only one of the three features of Enhanced
IDE. For example, fast data transfer rate support is be coming
standard on mid-range and high-end local bus systems. This single
feature could satisfy the users immediate requirements without the
need for the other features of Enhanced IDE.
In the future, if the same system is upgraded to add the remaining
features of Enhanced IDE, users may be forced to purchase an Enhanced
IDE package that contains a feature already installed. This could
result in unnecessary costs, integration conflicts, and in-
compatibility with original factory implementations.
Fast ATA, on the other hand, represents only the fast data transfer
rates for ATA hard drives (support for PIO mode 3 or 4 and DMA mode
1 or 2). Fast ATA and Fast ATA-2 data transfer rates can be easily
achieved when the system BIOS and hard drive suppo rt the PIO and
DMA protocols.
BIOS that supports Fast ATA does not necessarily support high-
capacity addressing, dual host adapters or non-hard drive
peripherals. But these features are being introduced independently
by system manufacturers in order to compete in the PC marketplace.
All of Quantum's disk drives designed for PCs now support Fast ATA,
and new products with Fast ATA support will be introduced in early
1995. The drives are also fully backward compatible with older ATA/
IDE (non-Fast ATA) BIOS.
The Quantum drives support both the Extended CHS (Cylinder Head
Sector) and LBA (Logical Block Address) addressing methods in
overcoming the 528 MB DOS capacity barrier. Quantum drives can also
be used with dual host adapters.
Finally, there are no incompatibilities with Quantum hard drives
that would prevent computer systems from supporting non-hard drive
peripherals.
Quantum drives that support Fast ATA include the following families:
Quantum ProDrive LPS 170/210/340/420
Quantum ProDrive LPS 270/540
Quantum Maverick 270/540
Quantum Lightning 365/540/730
Quantum Daytona 127/170/256/341/514
Fast ATA and Fast ATA-2 are important technologies that can take
advantage of the performance provided by the latest high-speed
microprocessors and bus architectures. The high-speed interfaces
are based on industry standard specifications and are the least
expensive way to achieve faster disk drive data transfer rates.
Fast ATA is not a group of features that requires an extremely
high level of integration, and only represents the fast data transfer
rates for ATA hard drives (PIO mode 3 or 4 and DMA mode 1 or 2).
