Description

Data storage device and method for maintaining normal boot operation of data storage device

technical field

The invention relates to a data storage device and a method for maintaining the normal boot operation of the data storage device.

Background technique

When the computer is used, the operating system is often damaged due to improper operation, poisoning or power failure. In the past, before the computer was shipped, the computer manufacturer would include a recovery disc. The recovery disc contains a recovery file of an operating system (such as an image file of the operating system). When the operating system of the computer is damaged, the user can execute a restoring program of the operating system through the restoring file of the restoring CD. However, the recovery disc is easily lost or scratched, so that the recovery process of the operating system often cannot be executed smoothly.

Alternatively, the conventional operating system restore procedure can also be executed by a miniaturized system. A data storage device inside the computer is divided into an operating system area and a system restore area. The operating system area stores an operating system, and the system restore area stores a system image file and a miniaturized system (such as Windows PE). When the user wants to execute the operating system recovery program of the computer, he presses a recovery key electrically connected to the motherboard to trigger the operating system recovery function. After the operating system restore function is triggered, the BIOS uses the system restore area to perform booting. After the system recovery area is turned on, the operator operates the miniaturized system to decompress the system image file, and uses the decompressed system image file to restore the operating system.

To execute the operating system restoration program with a miniaturized system, the file format of the system image file and the version of the operating system must be able to be resolved by the miniaturized system, otherwise, the system image file cannot be unpacked and the operating system cannot be restored. Therefore, most of the miniaturized systems that perform the operating system recovery program are only suitable for use on computers with the Microsoft Windows operating system.

Furthermore, most of the operating systems in industrial control equipment currently use non-windows operating systems, such as Linux and TinyOS. If the miniaturization system is used to execute the operating system restoration program of the industrial control equipment, it is necessary to redesign the software architecture of the miniaturization system according to the version of the operating system adopted by the industrial control equipment, otherwise the restoration process of the operating system of the industrial control equipment will not be completed smoothly. Here, redesigning the miniaturization system will cause a lot of troubles for software designers of industrial control equipment.
