Quantum Quantum Bigfoot CY User manual

The Market
Every year the demand for hard disk
storage doubles. Glance down the soft-
ware aisle of any computer store and
you’ll see why: “software inflation”.
Today’s graphical operating systems,
such as Windows®95, use up to 60
megabytes of storage space. CD-ROM–
based multimedia applications, educa-
tional applications, and games gobble
up to 40 megabytes of disk space each.
On top of that, many people store e-mail
messages and downloaded images from
digital cameras and the Internet.
To satisfy this rapidly growing mar-
ket, Quantum created the Bigfoot™5.25-
inch disk drive series. By combining
advanced recording technologies with
the increased data area of 5.25-inch
disks, the Bigfoot CY drive delivers the
best dollar-per-megabyte value in the
industry today.
Outstanding Performance for
Multimedia and Beyond
Multimedia applications benefit from
greater sequential transfer performance.
The large-capacity data tracks of
Bigfoot CY disks deliver exceptional
sequential performance, making the
drive perfect for multimedia.
To enhance performance further,
Bigfoot CY is designed with Quantum’s
proprietary technologies for minimizing
host delays and increasing sequential
data performance—multiple AutoRead,
multiple AutoWrite, and AutoTransfer
capabilities. In addition, we included a
Fast ATA-2 interface that delivers local-
bus AT Programmed Input/Output (PIO)
Mode 4 and Multiword DMA Mode 2
data transfers of up to 16.6 megabytes

per second. We also included a 128-
kilobyte buffer with Quantum’s DisCache
adaptive, segmented drive-to-host caching
technology to enhance high-speed data
transfers.
Easy Installation
Installing a Bigfoot CY drive is a snap,
whether you’re building a new system
or upgrading an existing PC. It’s the
same width as a CD-ROM drive, so it fits
conveniently in any standard 5.25-inch
drive bay. The Bigfoot CY drive also uses
the standard AT interface and cables—and
supports the same master/slave config-
urations as 3.5-inch disk drives. That’s
why no matter whether you’re building
a new system or upgrading an existing
system, installing a Bigfoot CY drive is
simple and straightforward.
Reliability and Versatility
We designed the Bigfoot CY drive using
as many field-proven components as
possible to give consumers years of
trouble-free operation. Using advanced
ASIC technology, we also implemented
automatic, double-burst, on-the-fly error
detection and correction to ensure rock-
solid reliability. The Bigfoot CY drive also
supports the S.M.A.R.T. (Self-Monitoring,
Analysis, and Reporting Technology)
Revision 2 industry-standard data-
protection firmware. With host computer
S.M.A.R.T. support, this feature provides
critical disk drive status and overall
health information that lets users avoid
catastrophic data loss. When you have
systems equipped with reliable and ver-
satile Bigfoot CY drives, your customers
stay sold on you—and on Quantum.
