Note:
Banding as defined here refers to the number of spare sectors provided per cylinder to reallocate
defective sectors. Band 2 cylinders are those nearer the inside diameter of the data surfaces.
These have additional spare sectors since the likelihood of defective sectors is higher in this
region. This feature does not affect the instantaneous media data rate which is constant across all
cylinders.
OPERATING ENVIRONMENT
The drive operates within its' performance limits when the following environment is maintained.
Product life calculations are based on the nominal environment for a typical application.
Humidity:
Operating 8% to 90% noncondensing
Storage 5% to 95% noncondensing
Shipping 5% to 100% (applies at a packaged level)
Wet Bulb Temperature:
Operating 80 degrees F (26.7 degrees C) maximum
Shipping/Storage 85 degrees F (29.4 degrees C) maximum
Elevation:
Operating -1000 to 10,000 feet
(-304 to 3,048 meters)
Shipping/Storage -1000 to 40,000 feet
