The term engaged drives calculates the number of drives that have had one or more activities (file access, file sharing, downloading etc.) performed in the report period.
Engaged Drives % Change
This is a ratio of the number of drives with activity for the report period and total drives that were active (not deleted) for the same time period. The drives are counted once regardless of the volume of activity.
Formula: number of drives with activity for report period / total existing drives for same report period.
