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
–1,000 to +10,000 feet (–305 to +3,048 meters)
b. Non-operating
–1,000 to +40,000 feet (–305 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 12, and in accordance with the restrictions of Section 8.5. Orientation of the
side nearest the LED may be up or down.
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 oper-
ation, shall operate error free while subjected to intermittent shock not exceeding 65 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
abnormal levels may promote degraded operational performance during the abnormal shock period. Speci-
