Case:
The driving recorder contains a 16GTF memory card. For a period of time, the data is maliciously deleted and needs to be recovered
Solution:
Since the TF card uses the FAT32 file system, the directory item of the file after the file is deleted has been cleared, and the file system cannot be scanned by the file system.So the engineer extracted from the data free space occupied by the file system, and tried to restore the data in the free space.According to the information provided by the user, it is found that the video recorded by the recorder is AVI video. By analyzing the underlying structure of the AVI video, it is recovered in accordance with the file type of AVI video in the extracted free space. The data recovery is successful successfully.
