Nonoperating vibration
6.5.2
The 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
6.5.3
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 disk drive will operate without a hard error while subjected to the following half-sine shock pulse.
Duration of 1 ms

1960 m/sec (200 G)

Table 20. Operating shock

The input level shall be applied to the normal disk drive subsystem mounting points used to secure the
drive in a normal system.
Nonoperating shock
6.5.4
The drive withstands the following half-sine shock pulse without any data loss or permanent damage.
Duration of 1 ms

9800 m/sec (1000 G)

Table 21. Nonoperating shock

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.
