SHOCK AND VIBRATION

The Maxtor Atlas 10K IV hard disk drive can withstand levels of shock and
vibration applied to any of its three mutually perpendicular axes, or principal base
axis, as specified in Table 4-8. A functioning drive can be subjected to specified
operating levels of shock and vibration. When a drive has been subjected to
specified non-operating levels of shock and vibration, with power to the drive off,
there will be no change in performance at power on.
When packed in its 1-pack shipping container, the Maxtor Atlas 10K IV drive can
withstand a drop from 30 inches onto a concrete surface on any of its surfaces, six
edges, or three corners. The 12-pack shipping container can withstand a drop from
30 inches onto a concrete surface on any of its surfaces, six edges, or three corners.

Annualized Failure Rate (AFR)
Drive reliability is closely related to the temperatures the drive is exposed to. The
operational design temperature ambient is 86°F (30°C). Temperature ambient
above 131°F (55°C) or below 41°F (5°C) may decrease drive reliability.
