If a VHD file fails to mount, the issue is often related to corruption within the virtual hard disk, damaged partition information, file system errors, or unexpected shutdowns that affected the VHD structure. Although the file may not open through Windows Disk Management or Hyper-V, the data stored inside it may still be recoverable.
A practical approach is to use a dedicated recovery solution such as the SysInfo VHD Recovery Tool. The software is designed to scan inaccessible or corrupted VHD and VHDX files and extract the available data without requiring the virtual disk to mount successfully. Users can add the damaged VHD file, select either Standard or Advanced scanning mode, and allow the software to examine the disk thoroughly.
Once the scan is completed, the tool displays the recovered files and folders in a hierarchical structure. Users can preview documents, images, and other recoverable items before saving them. The software also supports various file systems, including NTFS, FAT16, FAT32, FAT64, HFS+, EXTX, and RAW, as well as both MBR and GPT partition types.
