2.5.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.

Table 2-10. Shock and Vibration

Shock

Operating	10G (2 per second maximum)
Non-operating	70G (3 drops per axis maximum)
Non-operating Rotational Shock	10,000 rad/s2
Note: Half-sine wave of 3 ms duration without non-recoverable errors.

Vibration

Operating	5-20 Hz, 0.037 inch (peak to peak)
	20-400	Hz, 0.75G (0 to peak)
Non-operating	5-20 Hz, 0.098 inch (peak to peak)
	20-400	Hz, 2.0G (0 to peak)
Sweep Rate	One octave per minute (minimum)

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.
