First, step 301 is performed: providing a first connection mechanism, providing a second connection mechanism with the NAS device, and electrically connecting to the hard disk; providing a second connection mechanism to electrically connect to the host. "Monthly Referring to FIG. 2, the SATA switcher 20 is electrically connected to the NAS device 21, the hard disk 22, and the host 25 by three SATA ports. The sat^ 埠2〇1 is directly connected to the NAS device 21 as the first connection mechanism; the SATA port 202 is directly connected to the hard disk 22 as the second connection mechanism. The SATA port 203 is connected to the USB port SATA bridge μ as a third connection mechanism, and the USB to SATA bridge 23 is connected to the host 25 via the USB port 24. Then proceed to step 302: performing a first connection mechanism and a second connection according to the first switching signal to operate the storage device in the network attached storage mode. Please refer to FIG. 4' which is a schematic diagram of a network attached storage mode of the present invention. When the NAS device 21 is powered on, the NAS device 21 transmits a network attached storage device power-on signal to the SATA switch 20 via sata埠 201232266 201 to enter the network attached storage mode. After receiving the signal, the SATA switch 20 connects the SATA port 202 and the SATA port 201 to connect the hard disk 22 to the NAS device 2. At this time, the hard disk 22 corresponds to one of the NAS devices 21 as an auxiliary storage device. The network connection storage device power-on signal is the first switching signal of the present invention, and may be a general purpose input/output (GPIO) signal, but the invention is not limited thereto. In step 303, the second connection mechanism and the third connection mechanism are executed according to the second switching signal to operate the storage device in the direct attach storage mode. Next, please refer to Fig. 5, which is a schematic diagram of a direct attachment storage mode of the present invention. When the host computer 25 is electrically connected to the USB port 24, the USB port 24 transmits a host device connection signal sNAS device 21, and after receiving the signal, the NAS device 21 terminates the original network_storage mode and enters the direct attached storage mode. . The SATA port 202 and the SATA bee 203 ' are connected by the SATA switch 20 to connect the hard disk 22 to the host 25, and the hard disk is now the auxiliary storage device of the host 25. The line device connection = the second switching signal of the present invention may be - virtual bus line (10), VBUS) k number, but the invention is not limited thereto. After that, when the main unit 5 is disconnected ^ and ^ ^ 24 electrical connection, the host device is connected to the signal path to attach the money ^ terminates the original direct connection storage mode ^, return to the network == by the SATA switch 2 The connection 璋 202 and SATA 2 2G connect the hard disk 22 to the NAS device 21. , ''Ding, Shangshang Chen' The invention is in the purpose of the purpose, means and efficacy, in the 201232266 杳: the staff clearly, the characteristics of the technology is a major breakthrough, please ask the second ▲ 2 early grant patent , 俾 惠 惠 惠 , , , , , , , , , , , , , The second embodiment is merely illustrative of the principles of the invention and its utility, X: limiting the scope of the invention.
