Description of the Invention: [Technical Field] The present invention relates to a network attached storage (NAS), and more particularly to an external scale unit having an external storage medium and operable to be connected to a user terminal. And the basic NAS of the NAS. [Prior Art] Generally, a network attached storage (NAS) is connected to the network and has one or more hard disks. The NAS has an embedded operating system that does not have an external storage device and can be used as a function of a connected network. For example, a NAS can be a file server that is shared by multiple users. '' Because the NAS has an embedded operating system, it can be stored from the user terminal connected to the network. The file system stored in the towel (4) is provided to the user terminal. The file system cannot be used by the user. Good user sharing, thus limiting the formation of hard drives included in the NAS or deleting specific data from the hard drive. Since the NAS is a network device including an operating system, the deletion can be configured with an optical age unit such as a read only memory type (CD_ROM). Assume that the user terminal connected to the nas via the side channel allows the ship to be placed in the optical storage unit in the NAS, and the optical storage medium can be acquired to obtain the data, but the transmission rates are subject to the turtle depending on the line status and the network. Similar to ^ ’ in order to obtain data from a hard disk configured in a NAS, there may be a service limitation of the amount of data transfer, depending on the line speed and bandwidth of the network between the user terminal and the NAS. SUMMARY OF THE INVENTION The present invention is directed to providing a network-attached material, which is used by the ship's Na's _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Sinus, can be stored by providing a network attachment; (just come to the network storage (deleted) including the first and second storage interface access in the second mode of the special box _ encounter, dispute J逋b ,, and - control early, for performing a control operation based on the mode of the 201216055 mode switch selection, such that any card of one = Γ and the second mode is accessible: at least in accordance with the present invention On the one hand, the method of feeding and feeding, (10) state; „__糊-娜 H training any one; when [the second storage unit makes the ΐ ^ ^ in accordance with another aspect of the invention, provides a method of , the deletion has a hard 磾, 兮 ;; ^ kind of control with the control of the road to attach the memory (deleted) power; when requesting access to the i disk to the hard disk access state; and allow access to the hard ί The power should be applied to the hard disk to change the hard disk to the side of the control network.

Synchronizing the data chain sent by the request signal sync_req, and comparing the data keys stored in the hard disks i5〇a to 150n with the received force data link. When the comparison result indicates that it is stored in the network storage 200 - When the data stored in the hard disk is lost to the data, the path controller 117 requests the network storage device 2 to send the corresponding data. If the network storage device 200 sends the corresponding data. Data (data_send), the network controller 117 writes the sent data to the hard disk 150a to 150n to make a synchronization between the data of the network storage 2 and the hard disk to 201216055. The network controller 117 can periodically access and copy and store all the data stored in the network storage 200. When the mode is not properly executed by the mode switch mode, The error message can be sent to the pre-inquiry_address. The NAS control method according to the present invention can be implemented based on the process of the above-described embodiment. The nas control method can use a rod stored in the memory, because the NAS is uninterrupted. The device, which operates NAS ^ I j for 24 hours and 365 days in a row, is an important consideration. For the general NAS 'If the low power consumption mode is not used before, then the hard disk standby function is preferred to reduce the fr In the case of the standby function of the (four) disc, the power consumption can be effectively reduced, but the power of the disc is maintained as it is, resulting in continuous power consumption. This step reduces the power consumption while maintaining the standby function of the hard disk as it is, there is a k-like The force requirement: simulating the existing standby mode while effectively interrupting the power of the hard disk. First, FIG. 29 illustrates a nas control method for reducing power consumption according to the present invention. 磾ΐ〇ΐίΓ图'#入人硬碟After the financial formula, the control element ug is in the power-off state (S3〇〇) compared to the hard disk 〖50. After the correct reading 5〇* is the disambiguating electric secret, the control unit (10) performs the pre-power (', The post-execution_normally causes the hard disk 150 to display ί Γ = operation (S31G). Then the control unit iig interrupts the power supplied to the hard disk 150 to cut off the power of the hard disk 15 (s3i5). The power supplied to the hard disk (9), thereby making it possible to reduce more power consumption when the standby mode is driven earlier than the hard disk 150. Stone 9 f 'when requesting access to the hard disk 150, the The control unit 110 determines whether the = (9) ^ is the off state (S35G). After the hard disk m is not in the power failure, the control unit το 11G enters the hard disk 15G ', _ 15 〇 When in the _ state, the control unit (9) is called by power, and she is __= 9 201216055 (S360). Then the control unit 11 waits until the hard disk i5 enters the ready state (8) to take the normal operation mode of the hard disk 15 (S37〇). In this mode t, the power supply and the situation of the hard disk are low. Controlled in power mode = 4 uses the same - hard disk standby function to reduce power consumption while maintaining low power mode power. Therefore, in order to minimize the power consumption of the NAS, it is possible to further reduce the power consumption by controlling the power of the hard disk at the same time as the simulation mode of the low-power mode, in which the standby function of the hard disk 4 is used to reduce the power. Consumption without using the system at the same time. Figure 10 is a flow chart illustrating a process of supplying power to a hard disk when the NAS wakes up from a standby mode according to an embodiment of the present invention. In the case where two or more hard disks are set, power can be supplied to the hard disk at the same time or sequentially to drive them. Referring to Fig. 10', when the NAS is requested to wake up from the standby mode, the control unit 11 determines = slave (four) 15G closed drive (delivery). The synchronization can be preset by the phase_menu. After the step S400 of setting the synchronous driving is determined, the control unit 11 〇 synchronously supplies power to all the hard disks 150 to simultaneously drive them (S410). However, if the synchronous drive is not set, the control unit 11 sequentially drives the hard disk 15 (S415). For example, after the control unit 11 supplies power to the first hard disk 15 to be applied, the normal driving of the first hard disk 15A is completed, and the control unit 11 can supply power to the second hard disk to drive it. Synchronous driving of the hard disk 150 can result in a sudden increase in power consumption, but has the advantage of quickly transitioning the hard disk 15 to the normal mode.
