The Quantum Fireball ST AT 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.


CS Cable Select Jumper
When two Fireball ST AT 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.

Master with Slave Present Jumper Configuration
Present (SP) jumper implements one of two possible configurations:

    CS jumper installed and the Cable Select signal set to 0),
    adding an additional jumper (both jumpers DS and CS now installed)
    will indicate to the drive that a Slave drive is present. This
    Master with Slave Present jumper configuration 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.

 Jumper Parking (PK) Position
 drive in systems that do not support Cable Select. The pins used for
 the parking position are vendor unique. The drive will bias the
 parking position pins to detect the presence of this jumper. When
 doing so it will maintainn a minimum impedance of 4.7K  to the +5
 volt supply and 2.4K  to ground.

The unused position, may be also used as a jumper paring position,
if desired.

Air Filtration
The Fireball ST AT 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 0.3 micron filter.

General Description
Quantum's Fireball ST 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.

Advanced Technology (AT) interface.

The Fireball ST 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

Formatted Capacity
At the factory, the Fireball ST AT receives a low-level format that
creates the actual tracks and sectors on the drive.

Data Transfer Rates
132 Mbits/s in burst. Data is transferred from the read buffer to the
IDE bus at a rate up to 16.67 MB/s, using programmed I/O with IORDY,
or at a rate of up to 33 MB/s using Ultra DMA/33.

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 sophisticated error correction
codes. Quantum Fireball ST AT series hard disk drives implement
10(14) bits read.

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
the disk stack and a locking arm that restrains the actuator arm

of air across the airvane increases with disk ratation, the locking
return mechanism automatically pulls the actuator into the landing
zone, where the AIRLOCK holds it in place.

Disk Caching
The Fireball ST AT hard disk drive incorporates DisCache, a 87K disk
cache, to enhance drive performance. This integrated feature is
user-programmable and can significantly improve system throughput.

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

If more than 32 sectors are found defective within 65,504, the above
inline sparing technique is applied to the 32 sectors only. The
remaining defective sectors are replaced with the nearest available
pool of spares.

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
PowerPC-based computers offer processor speeds many times faster
data transfer rate of 132 MB/second.

Faster buses mean that data can be transferred from the storage
other high-speed components in the system and removing the
ATA helps bring very high performance to desktop PC systems.

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

local bus systems. The hardware connection can be made using a
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.

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
adapter, not the drive.

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-
only for the storage peripherals but also for host adapters, core
major block of PC architecture.

There is no central industry-supported standard that controls the
feature could satisfy the users immediate requirements without the
need for the other features of Enhanced IDE.

IDE package that contains a feature already installed. This could
result in unnecessary costs, integration conflicts, and in-
compatibility with original factory implementations.

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.

and new products with Fast ATA support will be introduced in early
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

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

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
