SHOCK AND VIBRATION

The Quantum Atlas 10K II Ultra 160/m SCSI 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 disk drive has been
subjected to specified non-operating levels of shock and vibration, with power to the
disk drive off, there will be no change in performance at power on.

When packed in its single-pack shipping container, the disk drive can withstand a
drop of 36 inches onto a concrete surface on any of its six faces, three edges, or one
corner. The 12-pack shipping container can withstand a drop from 30 inches onto a
concrete surface on any of its six faces, three edges, or one corner.
