6.5.4
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 5, and in accordance with the restrictions of Section 10.3.
6.5.4.1
Shock
a. Operating—normal
The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not exceeding:
• 40 Gs at a maximum duration of 11ms (half sinewave)
• 25 Gs at a maximum duration of 2ms (half sinewave)
Shock may be applied in the X, Y, or Z axis. Shock is not to be repeated more than once every 2 seconds.
b. 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.
The drive subjected to nonrepetitive shock not exceeding the three values below, shall not exhibit device damage or per-
formance degradation.
• 80 Gs at a maximum duration of 11ms (half sinewave)
• 400 Gs at a maximum duration of 2ms (half sinewave)
• 300 Gs at a maximum duration of 0.5ms (half sinewave)
Shock may be applied in the X, Y, or Z axis.
c. Packaged
Seagate finished drive bulk packs are designed and tested to meet or exceed applicable ISTA and ASTM standards. Vol-
ume finished drives will be shipped from Seagate factories on pallets to minimize freight costs and ease material han-
dling. 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.
