mal levels may promote degraded operational performance during the abnormal shock period. Specified
operational performance will continue when normal operating shock levels resume. Shock may be applied
in the X, Y, or Z axis. Shock is not to be repeated more than two times per second.
c. Non-operating
The limits of non-operating shock apply to all conditions of handling and transportation. This includes both
isolated drives and integrated drives.
The drive subjected to non-repetitive shock not exceeding 75 Gs at a maximum duration of 11 msec (half
sinewave) will not exhibit device damage or performance degradation. Shock may be applied in the X, Y, or
Z axis.
The drive subjected to non-repetitive shock not exceeding 140 Gs at a maximum of 2 msec (half sinewave)
will not exhibit device damage or performance degradation. Shock may be applied in the X, Y, or Z axis.
d. Packaged
Disc drives shipped as loose load (not palletized) general freight will be packaged to withstand drops from
heights as defined in the table below. For additional details, refer to Seagate specifications 30190-001
(under 100 lbs/45 kg) or 30191-001 (over 100 lbs/45 kg).
6.4.4.2 Vibration
a. Operating (normal)
The drive as installed for normal operation will operate error free while subjected to continuous vibration not
exceeding:
5–350 Hz @ 0.5 G
Vibration may be applied on the X, Y, or Z axis.
b. Operating (abnormal)
Equipment as installed for normal operation will not incur physical damage while subjected to periodic vibra-
tion not exceeding:
15 minutes of duration at major resonant frequency
5–400 Hz @ 0.75 G
Vibration occuring at these levels may degrade operating performance during the abnormal vibration
period. Specified operating performance will continue when normal operating vibration levels are resumed.
This assumes system recovery routines are available. Abnormal vibration may be applied on the X, Y, or Z
axis.
c. Non-operating
The limits of non-operating vibration apply to all conditions of handling and transportation. This includes
both isolated drives and integrated drives.
The drive will not incur physical damage or degraded performance as a result of continuous vibration not
exceeding:
5–22 Hz @ 0.081 in. (2.05 mm) displacement
22–350 Hz @ 2.00 Gs
Vibration may be applied in the X, Y, or Z axis.
6.4.5 Air cleanliness
The drive is designed to operate in a typical office environment with minimal environmental control.
