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.
1.2.6.2.1
These drives comply with the performance levels specified in this document when subjected to a maximum operating
shock of 70 Gs (read) and 40 Gs (write) based on half-sine shock pulses of 2ms. Shocks should not be repeated more
than two times per second.
1.2.6.2.2
The nonoperating shock level that the drive can experience without incurring physical damage or degradation in
performance when subsequently put into operation is 250 Gs based on a nonrepetitive half-sine shock pulse of 2ms
duration.
1.2.6.3

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.
