www.seagate.com Drive Specifications 2.9.5 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. 2.9.5.1 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 2ms during read operations. Shocks should not be repeated more than two times per second. 2.9.5.2 Nonoperating shock 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 (for 2TB model) and 350 Gs (for 1TB) based on a nonrepetitive half-sine shock pulse of 2ms duration. 2.9.6 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, with linear swept sine inputs. 2.9.6.1 Operating vibration The maximum vibration levels that the drive may experience while meeting the performance standards specified in this document are specified below. 2Hz to 22Hz 22Hz to 350Hz 350Hz to 500Hz 0.25 Gs (Limited displacement) 0.50 Gs 0.25 Gs 2.9.6.2 Nonoperating 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. 5Hz to 22Hz 22Hz to 350Hz 35Hz to 500Hz 3.0 Gs (limited displacement) 3.0 Gs 3.0 Gs Video 3.5 HDD Product Manual, Rev.
