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 for a duration
of 15 minutes per axis. The PSD levels for the test simulating the shipping and relocation environment is
shown below.

6.6.2.2 Swept sine vibration
! 5 G (zero-to-peak), 10 to 500 to 10 Hz sine wave
! 0.5 oct/min sweep rate
! 25.4 mm (peak-to-peak) displacement, 5 to 10 to 5 Hz
6.6.3 Operating shock
The hard disk drive meets the criteria in the table below while operating under these conditions:
! The shock test consists of 10 shock inputs in each axis and direction for a total of 60.
! There must be a minimum of 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.
