SHOCK AND VIBRATION
The Quantum Fireball Plus AS 10.2/20.5/30.0/40.0/60.0 GB AT hard disk drives
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 nonoperating levels of shock and vibration,
with power to the drive off, there will be no loss of user data at power on.
When packed in its 1-pack shipping container, the Quantum Fireball Plus AS drives
can withstand a drop from 30 inches onto a concrete surface on any of its surfaces,
six edges, or three corners. The 20-pack shipping container can withstand a drop
from 30 inches onto a concrete surface on any of its surfaces, six edges, or three
corners.
