Before handling the Maxtor hard disk drive some precautions must to be taken to
ensure that the drive is not damaged. Use both hands while handling the drive and
hold the drive by its edges. Maxtor drives are designed to withstand normal handling,
however, hard drives can be damaged by electrostatic discharge (ESD), dropping the
drive, rough handling, and mishandling. Use of a properly grounded wrist strap to the
earth is strongly recommended. Always keep the drive inside its special antistatic bag
until ready to install.
Note:
To avoid causing any damage to the drive do not touch or remove
the Printed Circuit Board (PCB) or any of its components when
handling the drive. Doing so will cause ESD damage to the drive.

Mean Time Between Failures (MTBF):
The projected field MTBF is 800,000
hours. The Maxtor MTBF numbers
represent Bell-Core TR-332 Issue #6,
December 1997 MTBF predictions and
represent the minimum MTBF that
Maxtor or a customer would expect from
the drive.
Component Life:
5 years
Preventive Maintenance (PM):
Not required
Start/Stop:
50,000 cycles @ ambient
Note:
Drive reliability is closely related to the temperature the drive is ex-
posed to. The operational design environment is 35°C at 71% uti-
lization or 6240 POH/year.
