b. Non-operating
–40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This 
specification assumes that the drive is packaged in the shipping container designed by Seagate for use with 
drive.

Relative humidity
 
The values below assume that no condensation on the drive occurs.
a. Operating
5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.
b. Non-operating
5% to 95% non-condensing relative humidity.
6.4.3
Effective altitude (sea level) 
 
a. Operating
–200 to +10,000 feet (–60.96 to +3,048 meters)
b. Non-operating
–200 to +40,000 feet (–60.96 to +12,210 meters)
6.4.4
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 11, and in accordance with the restrictions of Section 8.3.
6.4.4.1
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 msec (half sinewave). The drive, as installed for normal 
operation, shall operate error free while subjected to intermittent shock not exceeding 20 Gs at a maximum 
duration of 2 msec (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 msec (half sinewave). Shock occurring at 
HDA Temp.
