Environmental Specifications

2.5.1. Shock and Vibration

All shock and vibration specifications apply to the mounting and orientation conditions
described in section 2.3. Orientation axes are defined in Figure 2-4.

Sweep Rate
Operating Shock
WD Enterprise drives are tested by applying a linear shock in each axis, one axis at a
time, at a rate not exceeding two shocks per second.
The drive incurs no physical damage and no hard errors while subjected to intermittent
shock not exceeding the level listed in Table 2-10. Operating performance may degrade
during periods of shock application.
Non-operating Shock
WD Enterprise drives are tested by applying a linear shock in each axis, one axis at a
time. A maximum of three shocks per axis is applied.
The drive incurs no physical damage when subjected to non-repetitive shocks not
exceeding the level listed in Table 2-10.
Non-operating Rotational Shock
WD Enterprise drives are tested by applying a rotational shock in each direction, about
each axis, one axis at a time.
The drive incurs no physical damage when subjected to rotational shocks not exceeding
the level listed in Table 2-10.
