description A system for mirroring data and disk drive device state over a network between a source computer including a first non-shared disk drive storage device and a target computer including a second non-shared disk drive storage device. The system includes layered software drivers installed within the source computer above the device driver for the first disk drive storage device for capturing and examining write requests directed to the first disk drive storage device, and transmitting the write request and extracted device state information to the target computer. Software drivers installed within the target computer above the device driver for the second disk drive storage device direct the received write requests to the second disk drive storage device, and the received device state information to volatile storage within the target computer.
