Multipurpose dual-interface storage device with data preservation function

The invention relates to a multi-purpose dual-interface storage device with data preservation function, which comprises a hard disk with a system platform and data built in, an arithmetic unit, a client transmission interface and a network transmission interface. Wherein the system platform is provided with an authentication unit, and the operation unit is provided with a formatting instruction, After the external client device is connected to the hard disk, you must be authenticated before you can read data from your hard drive, if you exceed that authorization period, or when the user decides to delete the data in the hard disk, the cloud or the operation unit can execute the formatting instruction to format the hard disk so as to erase the data in the hard disk, thereby not only preventing the data from being illegally stolen or used, but also restoring the dual-interface hard disk box to a general network portable storage device, so as to achieve the purpose of data preservation and multi-purpose. 本发明为种具备
