We test vibration two ways:
Operating: While operating, the product vibrates for a minimum of one
hour each at the X,Y, and Z axes at a rate of 15 minutes per sweep cycle over
a frequency range of 5 to 2000Hz.
Non-operating: With no power applied, the product vibrates for a minimum
of one hour each at the X,Y, and Z axes at a rate of 15 minutes per sweep
cycle over a frequency range of 5 to 2000Hz.

The Winchester disk drive of your mass storage system contains its own air
filtration system. The system permits circulation of internal air and equalization
