Which recovery mode should I use for a heavily corrupted VHD file?
For a heavily corrupted VHD file, the Deep Recovery mode is generally the most suitable option because it performs a more thorough scan to locate recoverable files and folders that may not be detected during a standard scan. SysInfo VHD Recovery Tool provides three recovery modes: Standard, Advanced, and Deep, allowing users to select a method based on the severity of VHD corruption. For minor issues, Standard Recovery may be sufficient, while Advanced Recovery can be useful for more complex corruption. When the VHD is severely damaged or other recovery attempts fail, Deep Recovery can help identify additional recoverable data. After scanning, you can preview the recovered files in a tree hierarchy and select the required data for saving. For safety, always work with a copy of the original VHD and save recovered data to a separate healthy drive.
