6.5.4.2
Vibration
a. Operating—normal
The drive as installed for normal operation, shall comply with the complete specified performance while subjected to con-
tinuous vibration not exceeding
5-500 Hz @ 0.5 G (zero to peak)
Vibration may be applied in the X, Y, or Z axis.
Operating normal translational random flat profile
10 - 500 Hz (translational random flat profile)
b. Non-operating
The limits of non-operating vibration shall apply to all conditions of handling and transportation. This includes both iso-
lated drives and integrated drives.
The drive shall not incur physical damage or degraded performance as a result of continuous vibration not exceeding
5-500 Hz @ 3.0 G (zero to peak)
Vibration may be applied in the X, Y, or Z axis.
Non-operating translational random flat profile
10 - 500 Hz (translational random flat profile)
6.5.5
Air cleanliness
The drive is designed to operate in a typical office environment with minimal environmental control.
6.5.6
Corrosive environment
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial
environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this
accelerated testing cannot duplicate every potential application environment.
Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals
as electronic drive component reliability can be affected by the installation environment. The silver, copper, nickel and gold
films used in Seagate products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur
is found to be the most damaging. In addition, electronic components should never be exposed to condensing water on the
surface of the printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%. Materials
used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should be minimized or
eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free
alternatives.
6.5.7
Acoustics
Sound power during idle mode shall be 3.1 bels typical when measured to ISO 7779 specification.
There will not be any discrete tones more than 9 dB above the masking noise on typical drives when measured according to
Seagate specification 30553-001. There will not be any tones more than 24 dB above the masking noise on any drive.
