6.6.2 Nonoperating vibration
The disk drive withstands the following vibration levels without any loss or permanent damage.
6.6.2.1 Random vibration
The test consists of a random vibration applied in each of three mutually perpendicular axes with the time
duration of 15 minutes per axis. The PSD levels for the test simulating the shipping and relocation envi-
ronment is shown below.

6.6.3 Operating shock
The hard disk drive meets the following criteria while operating in the conditions described below.
The shock test consists of ten shock inputs in each axis and direction for a total of 60.
There must be a minimum 3 seconds delay between shock pulses.
The disk drive will operate without a hard error while being subjected to the following half-sine shock
pulse.
