HANDLING THE DRIVE
Before handling the Quantum 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. Quantum 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 the
Printed Circuit Board (PCB) or any of its components when
handling the drive.

Mean Time Between Failures (MTBF): The projected field MTBF is 625,000
hours. The Quantum MTBF numbers
represent Bell-Core TR-332 Issue #6,
December 1997 MTBF predictions and
represent the minimum MTBF that
Quantum or a customer would expect
from the drive.
Component Life: 3 years
Preventive Maintenance (PM): Not required
Start/Stop: 40,000 cycles at ambient temperature
(minimum)
Note: CSS specification assumes a duty cycle of one power off oper-
ation for every one idle mode spin downs.
