c.Non-operating

The limits of non-operating vibration shall apply to all conditions of handling and transportation. This includes both isolated drives and integrated drives.

The drive shall not incur physical damage or degraded performance as a result of continuous vibration not exceeding:

5 - 22 Hz, swept sine: 0.25 G, (zero to peak)

22 - 350 Hz, swept sine: 5.0 G (zero to peak)

350 - 500 Hz, swept sine: 1.0 G (zero to peak)

10 - 500 Hz, random: 0.0118 G2/Hz Vibration may be applied in the X, Y, or Z axis.

7.5.5Air cleanliness

The drive is designed to operate in a typical office environment with minimal environmental control.

7.5.6Corrosive 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 corro- sive chemicals as electronic drive component reliability can be affected by the installation environment. The sil- ver, 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 vulca- nized 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.

7.5.7Acoustics

Sound power during idle mode shall be 3.25 bels typical when measured to ISO 7779 specification.

Sound power during operating mode shall be 3.35 bels typical when measured to ISO 7779 specification.

There will not be any discrete tones more than 10 dB above the masking noise on typical drives when mea- sured according to Seagate specification 30553-001. There will not be any tones more than 24 dB above the masking noise on any drive.

7.5.8Electromagnetic susceptibility
