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 10ms during read operations. Shocks should not be
repeated more than two times per second.

repeated more than two times per second.
2.9.5.2
Non-operating shock
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.
