Thank you for your interest in Maxtor hard disk drives. This manual provides technical information for
OEM engineers and systems integrators regarding the installation and use of Maxtor hard drives. Drive
repair should be performed only at an authorized repair center. For repair information, contact the Maxtor
Customer Service Center at 800-2MAXTOR or 408-922-2085.
CAUTION: Maxtor hard drives are precision products. Failure to follow these precautions and guidelines out-
lined 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) precau-
tions, 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.
3 During handling, NEVER drop, jar, or bump a drive.
4 Once 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.
6ELECTRICAL GROUNDING - For proper operation, the drive must be securely fastened to
a device bay that provides a suitable electrical ground to the drive baseplate.
Please do not remove or cover up Maxtor factory-installed drive labels. They contain information required
should the drive ever need repair.

Maxtor’s D740X-6L hard disk drives are part of a family of high performance, 1-inch-
high hard disk drives manufactured to meet the highest product quality standards.
These hard diskdrives use nonremovable, 3 1/2-inch harddisks and are available
with the ATA interface.
The Maxtor D740X-6L 20.0/40.0/60.0/80.0GB AT hard disk drives feature an
embedded hard disk drive controller, and use ATA commands to optimize system
performance. Because the drive manages media defects and error recovery internally,
these operations are fully transparent to the user.
The innovative design of the Maxtor D740X-6L hard disk drives incorporate leading
edge technologies such as Ultra ATA/133, Advanced Cache Management, Shock
Protection System™(SPS), Data Protection System (DPS) and Quiet Drive
Technology (QDT).These enhancedtechnologies enableMaxtorto produce afamily
