6.5.2 

Non-operating vibration 

The hard disk drive withstands the following vibration levels without any loss or permanent damage. 

6.5.2.1 

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.

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 delay of 3 seconds between shock pulses.   
The hard disk drive will operate without a hard error while subjected to the following half-sine shock 

pulse.

Non-operating shock 

The hard disk drive withstands the following half-sine shock pulse without any data loss or permanent 
damage.

Table 21 Non-operating shock 

The shocks are applied for each direction of the hard disk drive for three mutually perpendicular axes, 
one axis at a time. Input levels are measured on a base plate where the hard disk drive is attached with 
four screws.
