b. Non-operating
Non-operating temperature should remain between –40° to 158°F (–40° to 70°C) package ambient with a
maximum gradient of 36°F (20°C) per hour. This assumes that the drive is packaged in the shipping con-
tainer designed by Seagate.
6.4.2 Relative humidity
The values below assume that no condensation on the drive occurs.
a. Operating
5% to 90% non-condensing relative humidity with a maximum gradient of 10% per hour.
b. Non-operating/transit
5% to 95% non-condensing relative humidity with a maximum gradient of 10% per hour.
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. 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 8.4. 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, will operate error-free while subjected to intermittent shock not
exceeding 2.0 g at a maximum duration of 11 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 7.5 g 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-
fied 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 applies to all conditions of handling and transportation. This includes both
isolated drives and integrated drives.
The drive subjected to non-repetitive shock not exceeding 40 g at a maximum duration of 11 msec (half sin-
ewave) does not exhibit device damage or performance degradation. Shock may be applied in the X, Y, or Z
axis.
d. Packaged
Disc drives shipped as loose load (not palletized) general freight will be packaged to withstand drops from
heights as defined in the table below. For additional details, refer to Seagate specifications 30190-001
(under 100 lbs/45 kg) or 30191-001 (over 100 lbs/45 kg).
