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

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.

The hard disk drive meets the criteria in the table below while operating under these conditions: 

Ÿ The shock test consists of 10 shock inputs in each axis and direction for a total of 60. 
Ÿ There must be a minimum delay of 3 seconds between shock pulses.   

Ÿ The disk drive will operate without a hard error while subjected to the following half-sine shock pulse.

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