Effective altitude (sea level)
a. Operating
–1000 to +10,000 ft (–304.8 to +3048 m)

Shock and vibration
Shock and vibration limits specified in this document are measured directly on the drive chassis. If the drive is
installed in an enclosure to which the stated shock and/or vibration criteria is applied, resonances may occur
internally to the enclosure resulting in drive movement in excess of the stated limits. If this situation is apparent,
it may be necessary to modify the enclosure to minimize drive movement.

The limits of shock and vibration defined within this document are specified with the drive mounted by any of
the four methods shown in Figure 8, and in accordance with the restrictions of Section 11.3.

7.5.4.1
Shock
a. Operating—normal
The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not
exceeding 15 Gs at a maximum duration of 11 ms (half sinewave). The drive, as installed for normal opera-
tion, shall operate error free while subjected to intermittent shock not exceeding 40 Gs at a maximum dura-
tion of 2 ms (half sinewave). Shock may be applied in the X, Y, or Z axis.
exceeding 15 Gs at a maximum duration of 11 ms (half sinewave). The drive, as installed for normal opera-
tion, shall operate error free while subjected to intermittent shock not exceeding 40 Gs at a maximum dura-
tion of 2 ms (half sinewave). Shock may be applied in the X, Y, or Z axis.
b. Operating—abnormal
Equipment, as installed for normal operation, does not incur physical damage while subjected to intermit-
tent shock not exceeding 40 Gs at a maximum duration of 11 ms (half sinewave). Shock occurring at abnor-
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 shall apply to all conditions of handling and transportation. This includes
both isolated drives and integrated drives.

d. Packaged
Seagate finished drive bulk packs are designed and tested to meet or exceed applicable ISTA and ASTM
standards. Volume finished drives will be shipped from Seagate factories on pallets to minimize freight
costs and ease material handling. Seagate finished drive bulk packs may be shipped individually. For less
than full shipments, instructions are printed on the bulk pack carton for minimum drive quantities and proper
drive placement
