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 87000D8, 86480D8,
85250D6, 84320D5, 83500D4, 83240D4, 82560D3 and 81750D2.
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.
