Technical information

HGST Ultrastar C15K600 Hard Disk Drive Specification
52
No data loss: 30G, 2 ms duration, half sinewave shock pulse, write operation mode
The shock pulses of each level are applied to the drive, ten pulses for each direction and for all three mutually
perpendicular axes. There must be a minimum of thirty seconds delay between shock pulses. The input level is
applied to a base plate where the drive is attached using four mounting screws.
12.4
Non-operating Shock
The drive will not sustain permanent damage or loss of recorded data after being subjected to the environments as
described below.
12.4.1
Half sinewave Shock Pulse
100 G, 11 ms duration, half sinewave pulse
300 G, 2 ms duration, half sine wave pulse
200 G, 0.5 ms duration, half sinewave pulse
The shocks are applied in each direction of the drive for the three mutually perpendicular axes, one axis at a time.
The input level is applied to a base plate where the drive is attached using four mounting screws.
12.4.2
Rotational Shock
30,000 radians /second
2
, 1 ms duration
20,000 radians /second
2
, 2 ms duration
The shock input is applied around the axis of the actuator pivot. The shock input does not displace the heads from
the actuator latched position.
