Abstract
A disk drive management system includes a data storage device including an array of disk drives and a host computer for controlling the operation of the data storage device. The array of disk drives includes an operational drive pool including a number of online disk drives having data written to and read from by the host computer; a spares drive pool including a number of disk drives that are configured to be included in the operational drive group, but are offline while in the spares group; and a maintenance drive pool including a maintenance manager for testing faulty disk drives from the operational drive pool. When a faulty drive is transitioned from the operational drive pool upon the occurrence of a particular error, a disk drive from the spares drive pool is transitioned to the operational drive pool to take the place of the faulty drive.
