2.8.5 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.
2.8.5.1 Operating shock
These drives comply with the performance levels specified in this document when subjected to a maximum
operating shock of 70 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more
than two times per second.
2.8.5.2 Nonoperating shock
1000 GB models
The nonoperating shock level that the drive can experience without incurring physical damage or degradation
in performance when subsequently put into operation is 300 Gs based on a nonrepetitive half-sine shock pulse
of 2 msec duration.
320 and 160 GB models
The nonoperating shock level that the drive can experience without incurring physical damage or degradation
in performance when subsequently put into operation is 350 Gs based on a nonrepetitive half-sine shock pulse
of 2 msec duration.
2.8.6 Vibration
All vibration specifications assume that the drive is mounted securely with the input vibration applied at the
drive mounting screws. Vibration may be applied in the X, Y or Z axis.
2.8.6.1 Operating vibration
The maximum vibration levels that the drive may experience while meeting the performance standards speci-
fied in this document are specified below.
2.8.6.2 Nonoperating vibration
The maximum nonoperating vibration levels that the drive may experience without incurring physical damage
or degradation in performance when subsequently put into operation are specified below.
2–22 Hz 0.25 Gs (Limited displacement)
22–350 Hz 0.50 Gs
350–500 Hz 0.25 Gs
5–22 Hz 2.0 Gs (limited displacement)
22–350 Hz 5.0 Gs
350–500 Hz 2.0 Gs
