ABSTRACT:
With detection of a selected error event involving a data storage drive and data storage media, a subsystem attempts to move the media to another drive, and conduct a similar operation. The subsystem separately tracks successive error events of individual drives and individual media, wherein a complete successful operation breaks the chain of the successive error events; and upon the number of successive error events reaching a threshold, fails the data storage drive or the data storage media. Error events are categorized into:1) error events before or during a mount of a media into a drive; and2) error events after a successful mount of a media into a drive; andconducts the tracking, comparing and failing steps separately for each of the categories for the drives and the media.
