ABSTRACT:
A method for monitoring the activity of a tape drive system having one or more electro-mechanical components that receive electrical current from a power supply. The method includes sampling an actual current supplied to an electro-mechanical component of a tape drive system from a power supply during an activity; reading a theoretical current for said activity from a memory; calculating a statistical value for said actual current and said theoretical current; comparing said statistical value to at least one threshold value; and outputting information to at least one of a user, another system, and another process based on said comparison of said statistical value to said at least one threshold value.
