Data storage device capable of self-accessing data file

A data storage device, comprising:

• a data storage unit comprising a controller and a plurality of flash memories connected to the controller;
• and
• a microprocessor, provided with a first operating system, and connected to the data storage unit via a high-speed data transmission interface;
• wherein a data is transmitted between the data storage unit and the microprocessor via the high-speed data transmission interface, the first operating system comprises a first file system, the first file system is configured with a driver program of the high-speed data transmission interface;
• wherein the first operating system of the microprocessor performs a data access operation for the data storage unit via the driver program to obtain a raw data from the data storage unit, the first file system of the first operating system performs a file parsing process for the raw data from the data storage unit to parse out a file information of the raw data from the data storage unit;
• wherein the data storage device comprises a network communication component, the microprocessor of the data storage device is connected to a management platform via the network communication element, the data storage device is connected to a host via the high-speed data transmission interface, the host is provided with a second operating system in the flash memories of the data storage unit of the data storage device, the second operating system comprises a second file system, the second file system is configured with the driver program of the high-speed data transmission interface;
• when the second operating system of the host has been damaged, the management platform sends a data access request for repairing the second operating system to the data storage device, the data access request includes a raw data used for restoring the second operating system;
• then, when the data storage device receives the data access request, the first operating system of the microprocessor of the data storage device performs the file parsing process to the raw data of the data access request via the first file system to obtain a system restoring file, and sends a data access command for repairing the second operating system to the controller, such that the controller repairs the second operating system of the host stored in the flash memories by the system restoring file.
