Seagate ST3750330SV Shock, Operating shock, Nonoperating shock 4, 3 and 2 disc models, Vibration

2.9.5Shock

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.

2.9.5.1Operating shock

These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 63 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more than two times per second.

2.9.5.2Nonoperating shock (4, 3 and 2 disc 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.

2.9.5.3Nonoperating shock (1 disc 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.

2.9.6Vibration

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.

2.9.6.1Operating vibration

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

5–22 Hz	0.25	Gs (Limited displacement)
22–350 Hz	0.50	Gs
350–500 Hz	0.25	Gs

2.9.6.2Nonoperating 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.

1000, 750 & 500 GB models

5–22 Hz	0.25 Gs (Limited displacement)
22–350 Hz	5.0 Gs
350–500 Hz	2.0 Gs
250 GB models
5–350 Hz	5.0 Gs
350–500 Hz	1.0 Gs
