Seagate ST9100011FS, ST950011FS manual Electromagnetic immunity, Vibration, Operating vibration

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 random vibration levels that the drive may experience while meeting the performance standards specified in this document are specified below. This specification does not cover connection issues that may result from testing at this level.

20–2000 Hz

16 Grms

2.9.6.2Nonoperating vibration

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

20–2000 Hz

16 Grms

2.10Electromagnetic immunity

When properly installed in a representative host system, the drive operates without errors or degradation in performance when subjected to the radio frequency (RF) environments defined in the following table:
