1. In an automated data storage library subsystem with storage shelves configured to store data storage media, a plurality of data storage drives, and at least one robot accessor configured to transfer data storage media between said storage shelves and said data storage drives, the method comprising:

  • detecting the occurrence of selected error events involving a data storage drive and selected error events involving a data storage media;

    upon a selected error event involving a data storage media, attempting to move said data storage media to another data storage drive, and conducting a similar operation to the operation that resulted in said selected error event;

    separately tracking successive error events of individual data storage drives and individual data storage media, wherein a complete successful operation of at least one of said data storage drive and said data storage media breaks the chain of said successive error events;

    comparing the number of said successive error events of at least one of said data storage drive and said data storage media to a threshold; and

    upon said number of said successive error events reaching said threshold, placing at least one of said data storage drive and said data storage media in a failed category.
