Before You Begin
Thank you for your interest in the Maxtor DiamondMax™ 1750 AT hard disk drives. This manual provides technical
information for OEM engineers and systems integrators regarding the installation and use of the 87000A8, 86480A8,
85250A6, 84320A5, 83500A4, 83240A4, 82560A3 and 81750A2.
Drive repair should be performed only at an authorized repair center. For repair information, contact the
Maxtor Customer Service Center at 800-2MAXTOR or 408-432-1700.
Before unpacking the hard drive, please review Sections 1 through 4.
CAUTION
Maxtor DiamondMax 1750 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.
1 BEFORE 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.
2 BEFORE removing drives from their packing material, allow them to reach room
temperature.
3 During handling, NEVER drop, jar, or bump a drive.
4 OnceadriveisremovedfromtheMaxtorshippingcontainer,IMMEDIATELYsecurethe
drivethroughitsmountingholeswithinachassis.Otherwise,storethedriveonapadded,
grounded,antistaticsurface.
5 NEVERswitchDCpowerontothedrivebyplugginganelectricallyliveDCsourcecable
into the drive's connector. NEVER connect a live bus to the drive's interface connector.
Please do not remove or cover up Maxtor factory-installed drive labels.
They contain information required should the drive ever need repair.

Power Requirements (Average)
Power Mode Definitions
Active
The drive is spinning and most circuitry is powered on. The drive is capable of responding to read commands in
the shortest possible time. Read/Write heads are positioned over the data area.
Idle
The drive is spinning, the actuator is parked and powered off and all other circuitry is powered on. The drive is
capable of responding to read commands within 40 ms.
Read/Write
Data is being read from or written to the drive.
Spin-up
The drive is spinning up following initial application of power and has not yet reached full speed.
Sleep
This is the lowest power state. The interface becomes inactive. A software or hardware reset is required to return
the drive to Active.
Standby
The spin motor is not spinning. The drive will leave this mode upon receipt of a command that requires disk
access. The time-out value for this mode is programmable. The buffer is active to accept write data.
Seek
A random access operation by the disk drive.

Maxtor does not differentiate between various usage profiles. (.e. power-on hours, power saving modes, non-
operating periods or operating temperatures within the published specification.)
Start/Stop Cycles – 50,000 (minimum)
This indicates the minimum cycles for reliable start/stop function at a ≥60% confidence level.
AFR – 1.7%
The annualized average failure rate (AFR) applies to the period prior to the expiration of component design life,
and is based on failures chargeable to Maxtor. Determination of the AFR takes into account: a.) in-warranty field
failure returns less quality acceptance-related failures and b.) an AFR equaling an exponentially weighted moving
and average monthly failure rate multiplied by 12.
Component Design Life – 5 years (minimum)
Component design life is defined as a.) the time period before identified wear-out mechanisms impact the failure
rate, or b.) the time period up to the wear-out point at which useful component life expires.
Quality Acceptance Rate – 99.85% (<1,500 DPPM)
The quality acceptance rate indicates the percentage of Maxtor products successfully installed by our customers,
and/or the number of defective parts per million (DPPM) encountered during the entire installation process.
Preventative Maintenance – None
Data Reliability
Data Errors (non-recoverable)* – < 1 per 1013 bits read
Seek Errors – < 1 per 106seeks
*Average data error rate allowed with all error recovery features activated.
Acoustic Noise
Recorded during Active/Idle mode. Average
Sound power (per ISO 7779, 10 microphone) 37 dBA
EPA Energy Star Compliance
Maxtor Corporation supports the goals of the U.S. Environmental Protection Agency’s Energy Star program to
reduce the electrical power consumption of computer equipment.

EMC/EMI
Radiated Electromagnetic Field Emissions - EMC Compliance
The hard disk drive mechanism is designed as a subassembly for installation into a suitable enclosure and is
therefore not subject to Subpart J of Part 15 of FCC Rules (47CFR15) or the Canadian Department of
Communications Radio Interference Regulations. Although not required, the disk mechanism has been tested
within a suitable end-use product and found to comply with Class B limits of the FCC Rules and Regulations of
the Canadian Department of Communications.
The CE Marking indicates conformity with the European Union Low Voltage Directive (73/23/EEC) when the
disk mechanism is installed in a typical personal computer. Maxtor recommends that testing and analysis for EMC
compliance be performed with the disk mechanism installed within the user's end-use application.
Canadian Emissions Statement
This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus as set out
in the radio interference regulations of the Canadian department of communications.
Le present appareil numerique n'emet pas de bruit radioelectriques depassant les limites applicables aux appareils
numeriques de Class B prescrites dans le reglement sur le brouillage radioelectrique edicte par le ministere des
communicationsduCanada.
Radiated Magnetic Field Emissions
Minimum of VDE Class B and MIL-STD-461/462, Method RE01 (stand-alone test configuration).
Radiated Electromagnetic Field Immunity
IEC 801-3, Class 2 compliance.
Radiated Magnetic Field Immunity
Per MIL-STD-461/462, Method RD01(15 Hz to 100 kHz, stand-alone test configuration).
Standard Test Methods
Traditional hard drive specifications are open to incorrect interpretation, but MIL-STD test methods accurately
measure how products perform in real-world conditions. These methods have gained worldwide acceptance since
they reflect actual environments, have well-defined test requirements, are easily understood and provide repeatable
results. They objectively demonstrate to our customers the reliable, durable design of Maxtor hard drives. Each MIL-
STD specification provides the basic method and condition information needed for reference by a knowledgeable
Test and Qualification Engineer.
Acoustic specifications such as sound pressure are misleading because the test methods used are not controlled by
recognizable standards. The sound pressure measurement itself is the least meaningful indicator of noise emissions as
it relates to the human ear. The specification of sound power, loudness and sharpness are considered the most
accurate acoustic measurement methodologies recognized by the leading acoustic measurement experts. ISO 7779,
sound power, ISO 532B, loudness and sharpness (proposed ANSI standard by Eberhard Zwicker) are repeatable test
methods providing results reproducible in any properly equipped acoustic lab.
Safety Regulatory Compliance
All Maxtor DiamondMax™ 1750 drives comply with relevant product safety standards such as CE, CUL, TUV and
UL rules and regulations. As delivered, DiamondMax 1750 hard disk drives are designed for system integration
before they are used.
