activity is required, the drive makes a transition to Standby mode. In both Idle and Standby mode, the drive
accepts all commands and returns to Active mode when disk access is necessary.
2.9 Environmental specifications
This section provides the temperature, humidity, shock, and vibration specifications. Ambient temperature is
defined as the temperature of the environment immediately surrounding the drive. Above 1000ft. (305 meters), the
maximum temperature is derated linearly by 1°C every 1000 ft.
Refer to Section 3.4 on page 24 for base plate measurement location.
2.9.1 Ambient temperature
2.9.2 Temperature gradient
2.9.3 Humidity
2.9.3.1 Relative humidity
2.9.3.2 Wet bulb temperature
2.9.4 Altitude
2.9.5 Shock
All shock specifications assume that the drive is mounted securely with the input shock applied at the drive
mounting screws. Shock may be applied in the X, Y or Z axis.
2.9.5.1 Operating shock
These drives comply with the performance levels specified in this document when subjected to a maximum
operating shock of 80 Gs based on half-sine shock pulses of 2ms during read operations. Shocks should not be
repeated more than two times per second. A maximum operating shock of 80 Gs based on half-sine shock pulses
of 10ms during read operations applies to the
