Abstract
This invention discloses a data access device for using in computer of power off status, which comprises a power multiplexer, a DC to DC converter, a serial bus signal to storage interface signal controller, a data storage interface signal multiplexer, and a controller. Therefore, if controller detects an external device wants to access data storage device of computer at power off, it will control power multiplexer to retrieve the standby power of the power device and process power transformation to provide a required power for driving the storage device, and by using serial bus signal to storage interface signal controller, external device can access the data from storage device at power off.
