2.8.3Altitude

Operating	–304.80 m to 3048 m (–1000 ft. to 10,000+ ft.)
Non-operating	–304.80 m to 12,192 m (–1000 ft. to 40,000+ ft.)

2.8.4Shock

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.

2.8.4.1Operating shock

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

2.8.4.2Non-operating shock

3TB, 2TB and 1TB models

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 2 ms duration.

2.8.5Vibration

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.

2.8.5.1Operating vibration

The maximum vibration levels that the drive may experience while meeting the performance standards specified in this document are specified below.

5Hz to 22Hz	0.25 Gs
22Hz to 350Hz	0.50 Gs
350Hz to 500Hz	0.25 Gs
20 - 1500Hz	12.5 rads/s2 w/RVFF
*(RROV)

* Rotary Random Operating 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. Throughput may vary if improperly mounted.

2.8.5.2Non-operating vibration

The maximum non-operating vibration levels that the drive may experience without incurring physical damage or degradation in performance when subsequently put into operation are specified below.

10Hz to 500Hz Linear Random
