6.4.2 Relative humidity
The values below assume that no condensation on the drive occurs.
a. Operating
5% to 90% relative humidity with a maximum gradient of 10% per hour.
b. Non-operating
5% to 95% 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 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, shall operate error free while subjected to intermittent shock not
exceeding 2 g at a maximum duration of 11 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 intermit-
tent shock not exceeding 10 g at a maximum duration of 11 ms (half sinewave). Shock occurring at abnor-
mal levels may promote degraded operational performance 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 drives and integrated drives.
The drive subjected to nonrepetitive shock not exceeding 75 g at a maximum duration of 11 ms (half sine-
wave) 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 100 g at a maximum duration of 2 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).
