Before You Begin
Thank you for your interest in Maxtor hard disk drives. This manual provides technical information for OEM engi-
neers and systems integrators regarding the installation and use of Maxtor hard drives. Drive repair should be per-
formed only at an authorized repair center. For repair information, contact the Maxtor Customer Service Center at
800-2MAXTOR or 303-678-2045.
CAUTION: Maxtor hard drives are precision products. Failure to follow these precautions and guidelines outlined
here may lead to product failure, damage and invalidation of all warranties.
1BEFORE unpacking or handling a drive, take all proper electro-static discharge (ESD) precautions,
including personnel and equipment grounding. Stand-alone drives are sensitive to ESD damage.
2BEFORE removing drives from their packing material, allow them to reach room temperature.
3During handling, NEVER drop, jar, or bump a drive.
4Once a drive is removed from the Maxtor shipping container, IMMEDIATELY secure the drive through
its mounting holes within a chassis. Otherwise, store the drive on a padded, grounded, antistatic surface.
5NEVER switch DC power onto the drive by plugging an electrically live DC source cable into the
drive's connector. NEVER connect a live bus to the drive's interface connector. (P68 only)
Please do not remove or cover up Maxtor factory-installed drive labels. They contain information
required should the drive ever need repair.

Regulatory Statements
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. Any modifications of this device - unless
expressly approved by the manufacturer - can void the user’s authority to operate this equipment
under Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This
device may not cause harmful interference and (2) This device must accept any interference that
may cause undesirable operation.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communications.
Howerver, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be deter-
mined by turning the equipment off and on, the user is encouraged to try to correct the interfer-
ence by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
NOTE: Additional information on the need to interconnect the device with shielded (data) cables or the need
for special devices, such as ferrite beads on cables, is required if such means of interference suppression was used
in the qualification test for the device. This information will vary from device to device and needs to be obtained
from the EMC group or product manager.
This Class B digital apparatus complies with Canadian ICES-003.

ABOUT THIS MANUAL
This chapter gives an overview of the contents of this manual, including the intended
audience, how the manual is organized, terminology and conventions, and references.
1.1 AUDIENCE
The Maxtor Atlas 15K II Product Manual is intended for reference by original
equipment manufacturers (OEMs) that are integrating the disk drive into a system or
subsystem, developers, and disk drive installers. Its primary audience is the OEM
technical staff that makes disk drive purchase and configuration decisions, and system
integrators that are responsible for the SCSI interface. This manual is not intended for
end-users and is not a users manual or an installation guide. The manual provides
information about installation, interface command implementation, maintenance, and
gives the general specifications of the drive.
1.2 MANUAL ORGANIZATION
This manual is organized into the following chapters:
• Chapter 1 – About This Manual
• Chapter 2 – General Description
• Chapter 3 – Installation
• Chapter 4 – Specifications
• Chapter 5 – SCSI Description
• Chapter 6 – Feature Descriptions
• Appendix A – Quick Reference
• Appendix B – Negotiated Page Information Page Reference
• Glossary

Maxtor Atlas 15K II 1-3
The typographical and naming conventions used in this manual are listed below.
Conventions that are unique to a specific table appear in the notes that follow that
table.
Typographical Conventions:
• Names of Bits: Bit names are presented in initial capitals. An example is
the Host Software Reset Bit.
• Commands: Firmware commands are listed as all capitals. An example is
MODE SELECT.
• Parameters: Parameters are given as initial capitals when spelled out, and
are given as all capitals when abbreviated. Examples are Prefetch Enable
(PE) and Cache Enable (CE).
• Hexadecimal Notation: The hexadecimal notation is given in 9-point
subscript form. An example is 30H.
• Signal Negation: A signal that is non-active or is in its non-asserted state.
• Messages: A message that is sent from the drive to the host is listed in all
capitals. An example is BUS DEVICE RESET.
Naming Conventions:
• Host: In general, the system in which the drive resides is referred to as
the host.
• Computer Voice: This refers to items you type at the computer
keyboard. These items are listed in 10-point, all capitals, Courier font.
