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 ar e specified with the drive mounted by any of the four methods  shown in 
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 G
s at a 
maximum duration of 11 ms (half sinewave). The drive, as installed for normal operation, shall operate error free while subject ed to 
intermittent shock not exceeding 25 Gs at a maximum duration 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 intermittent shock not exceedin g 40
Gs at a maximum duration of 11 ms (half sinewave). Shock occurring at abnormal levels may promote degraded operational perfor -
mance 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 dri
ves and 
integrated drives.
The drive subjected to nonrepetitive shock not exceeding 80 Gs at a maximum duration of 11 ms (half sinewave) shall not exhibit
 
device damage or performance degradation. Shock may be applied in the X, Y, or Z axis.
The drive subjected to nonrepetitive shock not exceeding 400 Gs at a maximum duration of 2 ms (half sinewave) does not exhibit 
device damage or performance degradation. Shock may be applied in the X, Y, or Z axis.
The drive subjected to nonrepetitive shock not exceeding 300 Gs at a maximum duration of 0.5 ms (half sinewave) does not exhibi t 
device damage or performance degradation. Shock may be applied in the X, Y, or Z axis.
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
