Display method and device for mirroring visualization

TL;DR: In this article, a mirroring visualization device consisting of a display module, mirroring module, and a recording module is presented, which includes the steps of recording the state state, displaying the sector state, carrying out mirroring, returning a state value, and judging whether a corresponding block display sector in a display interface is successfully recovered or not according to the return value stored in the mirroring state file.

Abstract: The invention discloses a mirroring visualization device which comprises a display module, a mirroring module and a recording module The invention further discloses a method based on the device The method comprises the steps of recording the sector state, displaying the sector state, carrying out mirroring, returning a state value, and judging whether a corresponding block display sector in a display interface is successfully recovered or not according to the return value stored in a mirroring state file The device for mirroring visualization has the following advantages that in the mirroring process, whether data in the corresponding sector is mirrored successfully or not can be seen, mirroring information is recorded, and frequent file writing operation is avoided; in the mirroring process or in the breakpoint resuming process, scroll bars can be dragged to check the mirroring state corresponding to a certain sector; when mirroring is stopped, or power is disconnected in the mirroring process, the sector position of current mirroring will be saved, when mirroring is carried out again, mirroring can start to be carried out from the stopping position, and the mirroring result can be checked and saved fast
