This chapter outlines the scope and contents of this manual. It contains information
about the intended audience, purpose of the manual, document organization, and
document conventions.
1.1 AUDIENCE
This manual was written for original equipment manufacturers (OEMs) that are
integrating a Quantum AtlasTM 10K II Ultra 160/m SCSI disk drive into a system or
subsystem. Its primary audience is the OEM technical staff that makes disk drive

1-4 Quantum Atlas 10K II Ultra 160/m SCSI Hard Disk Drives
This chapter summarizes the general functions and key features of the Quantum
10K II Ultra 160/m SCSI family of hard disk drives, and lists applicable standards
and regulations.
2.1 PRODUCT OVERVIEW
Quantum Atlas 10K II Ultra 160/m SCSI hard disk drives are part of a family of
high performance, 1-inch high (low profile) and 1.6-inch high (half-height) hard

drives are designed for high-end PC-based workstations, RAID storage systems,
digital video applications, database servers, file servers, and other storage systems
where high capacity, extraordinary performance, and reliability are critical. These
hard disk drives use nonremovable 3.5-inch hard disks and are available with the
following SCSI configurations:
• Ultra 160/m, Ultra2, Ultra SCSI 68-pin Wide (16-bit)
• Ultra 160/m, Ultra2, Ultra SCSI 80-pin SCA-2 (16-bit)

• MR heads and banded recording for higher overall bit-densities
• Hardware XOR to automatically detect and correct errors and defects in the data
stream for array applications (RAID)
• Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) Revision 2
support
• ORCA (Optimized Reordering Command Algorithm) and tagged command
queuing for greater throughput
• 8 MB Track-oriented segmented cache buffer with prefetch
• Automatic Power Management System with power-saving sub-states
• 10,000 rpm rotational speed yielding 3.0 ms average latency
Quantum Atlas 10K II Ultra 160/m SCSI Hard Disk Drives 2-1
General Description and Specifications
• 4.7 ms second average random seek time (read) and 7.9 ms average access-todata time for the 1.0-inch drives; 5.2 ms second average random seek time (read)
and 8.4 ms average access-to-data time for the 1.6-inch versions of the drive.
• Embedded servo system for exceptional head positioning accuracy and long life
• “Zero latency” reads and writes reduce data access time
• Full SCSI– 3 compliance 1 (compatible with SCSI-2 and SCSI–1)
• Advanced Ultra 160/m-LVD, Ultra2-LVD and Ultra SE Multimode SCSI with
68-pin wide connector or 80-pin SCA-2 connector
• Superior data integrity:
› 352-bit Reed-Solomon quad-burst ECC provides fast on-the-fly correction for
small errors and robust software-based correction for larger errors
› EDC internal protection from SCSI bus to media
2.3 STANDARDS AND REGULATIONS
The Quantum Atlas 10K II Ultra 160/m SCSI hard disk drives satisfy the following
standards and regulations:
• Underwriters Laboratory (U.L.): Standard 1950. Information technology
equipment including business equipment.
• Canadian Standards Assocation (CSA): Standard C.22.2 No. 950-M89.
Information technology equipment including business equipment
• European Standards (TÜV): Standard EN 60 950. Information technology
equipment including business equipment
• Federal Communications Commission (FCC): FCC Rules for Radiated and
Conducted Emissions, Part 15, Sub Part J, For Class B equipment
• CISPR: CISPR 22 Rules for Radiated and Conducted Emissions, for Class B
equipment
• Tested to comply with Australian requirements to carry C-Tick logo
2.4 HARDWARE REQUIREMENTS
The Quantum Atlas 10K II Ultra 160/m SCSI hard disk drives are completely
compatible with host computers and controllers that provide a 68-pin Wide or 80-pin
SCA-2 interface. A 50-pin to 68-pin adapter is required to use the 68-pin Wide drive
in a 50-pin cabling configuration.
1The drives are in compliance with the SCSI-3 draft proposed ANSI standards as
they exist at the time of product release; SCSI-3 features may not be enabled on
drives when shipped.

INSTALLATION
This chapter explains how to unpack, configure, mount, and connect the Quantum
Atlas 10K II Ultra 160/m SCSI hard disk drive prior to operation.
3.1 SAFETY, HANDLING, & ELECTROSTATIC DISCHARGE PROTECTION
3.1.1 Safety Precautions
For your safety, follow all safety procedures described here and in other sections of
the manual.
• Remove power from the computer system (or expansion unit) before installing or
removing the drive to prevent the possibility of electrical shock or damage to the
drive. Unplug the unit containing the drive to provide an added measure of
safety.
• Read, understand, and observe all label warnings.
3.1.2 Handling
Damage to the drive can occur as the result of careless handling, vibration, shock,
or electrostatic discharge (ESD). Always handle the drive with care to avoid damage
to the precision internal components.
CAUTION
A 1/4-inch drop onto a hard surface can damage the drive
Follow these guidelines to avoid damage to the drive:
• Always observe prescribed ESD precautions.
• Keep the drive in its anti-static bag until ready to install.
• Always use a properly fitted wrist strap or other suitable ESD protection when
handling the drive.
• Hold drive only by its sides. Do not touch any components on the PCBA.
• Always handle the drive carefully and gently. A drop of 1/4 inch onto a bench or
desktop can damage a drive.
• Do not bump, jar, or drop the drive. Use care when transporting the drive.
• Always gently place the drive flat, PCB side down, on an appropriate ESDprotected work surface to avoid the drive being accidentally knocked over.
• Do not pack other materials with the drive in its shielded bag.
• Place the drive in the anti-static bag before placing in shipping container.
• Do not stack objects on the drive.

Installation
• Never force the drive or the mounting brackets into the drive bay.
• Do not expose the drive to moisture.
• Do not damage any seals on the drive; doing so may void the warranty.
3.1.3 Electrostatic Discharge (ESD) Protection
Various electrical components within the disk drive are sensitive to static electricity
and Electrostatic Discharge (ESD). Even a static buildup or discharge that is too
slight to feel can be sufficient to destroy or degrade a component's operation.
To minimize the possibility of ESD-related damage to the drive, we strongly
recommend using both a properly installed workstation anti-static mat and a
properly installed ESD wrist strap. When correctly installed, these devices reduce the
buildup of static electricity which might harm the drive.
Observe the following precautions to avoid ESD-related problems:
• Use a properly installed anti-static pad on your work surface.
• Always use a properly fitted and grounded wrist strap or other suitable ESD
protection when handling the drive and observe proper ESD grounding
techniques.
• Hold the drive only by its sides. Do not touch any components on the PCBA.
• Leave the drive in its anti-static bag until you are ready to install it in the
system.
• Place the drive on a properly grounded anti-static work surface pad when it is
out of its protective anti-static bag.
• Do not use the bag as a substitute for the work surface anti-static pad. The
outside of the bag may not have the same anti-static properties as the inside. It
could actually increase the possibility of ESD problems.
• Do not use any test equipment to check components on the electronics module.
There are no user-serviceable components on the drive.
