Frequently Asked Questions

A VHDX can contain an entire virtual machine's data. Finding a file with the right name is not enough: it must be complete, and its relationship to checkpoints and configuration files must remain clear.

Identify the Missing Virtual Disk

Check the VM's configured virtual-hard-disk path and whether the file was moved to another volume. Review your backup system and any checkpoint chain without deleting or merging files yet.

A differencing disk or checkpoint may depend on a parent VHDX. Guessing which file to attach can damage the only usable chain, so keep copies of all surviving components.

Stop Writes to the VM Storage Disk

Shut down the affected VM if possible, and avoid creating new virtual disks or checkpoints on the same physical source. New large writes can overwrite deleted blocks.

Prepare another physical drive with room for the whole VHDX and related files. If the volume shows hardware errors, prioritize controlled imaging or specialist help.

Scan for the Lost VHDX File

Qiling Deep Data Recovery provides a visual scan of storage that Windows can detect. In this case, the physical disk that stored the VHDX must be stable and readable; file-size estimates help identify candidates. A listed file is only a candidate until you open and verify its recovered copy.

Step 1. Check Configuration and Backup

Record the VM's configured disk path and examine backups and surviving checkpoint files. Do not merge or delete a checkpoint during the search.

Step 2. Choose Fast or Disk Scan

Use Fast Scan if a VHDX was recently deleted from an accessible volume. Use Disk Scan if its partition disappeared; stop if hardware is unstable.

Step 3. Select the VM Storage Disk

Choose the physical disk that held the virtual disk by model and capacity, not merely the disk containing the Hyper-V application.

Step 4. Inspect Large Candidates

Filter for .vhdx and compare file sizes. The results pane may not preview a virtual disk's guest data; treat candidates as unverified.

Step 5. Recover to Separate Storage

Click Recover and save candidate files to another disk. Make a working copy before attaching or inspecting a recovered virtual disk.

Test Without Changing the Original

Validate a copy in a controlled environment and preserve the recovered original. Missing parent or checkpoint files can prevent the VM from opening even when a VHDX itself appears intact.

If the VM contains critical production data, restore from a verified VM backup or obtain specialist help rather than repeatedly experimenting on the only copy.

Frequently Asked Questions

Can I preview guest files directly in scan results?

Do not assume so. Recover the VHDX, then test a copy with appropriate virtual-disk tools.

Will one VHDX recover a checkpoint chain?

Not necessarily. Differencing disks may require parent files and configuration information.

Should I restart the affected VM now?

Avoid new writes to the source until its virtual disks and backups are accounted for.
