Abstract
A method of insuring recovery of a quantity write request data in a storage device having a plurality of controllers includes the steps of (1) providing a primary controller for storing the write request data received from a host device, (2) providing an alternate controller having a memory area allocated for use by the primary controller, (3) maintaining a first control block in the primary controller for indicating status of the write request data stored in the primary controller, and (4) maintaining a second control block in the alternate controller for indicating status of the write request data stored in the primary controller.
