2.9.6 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.
2.9.6.1
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 2 times per second.
2.9.6.2
Non-operating shock
3TB and 4TB
The non-operating 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 non-repetitive half-sine shock pulse of
2ms duration.
