Hyper-V Data Recovery
Got a Crashed Hyper-V Host? To find out how you can regain lost data same or next day, call now!
Disk Doctors provides professional data recovery for Microsoft Hyper-V virtual environments, including crashed Hyper-V hosts, corrupted or deleted VHD/VHDX files, failed Cluster Shared Volumes, and RAID or SAN storage hosting virtual machines. Our engineers recover virtual machine data at both the hypervisor and guest file-system level.

Hyper-V host crashed or a VHDX file corrupted? Every minute counts.
Continuing to run a failing volume risks overwriting recoverable virtual machine data. Power the environment down now and let our engineers run a free evaluation before you risk anything further.
What is Hyper-V Data Recovery, and Why is it Needed?
Microsoft Hyper-V stores virtual machines as VHD or VHDX virtual disks, often sitting on Cluster Shared Volumes (CSVs) formatted with NTFS or ReFS and backed by RAID or SAN storage. When a CSV becomes corrupted, a checkpoint fails to merge, or the underlying storage fails, an entire virtual machine and everything on it can become inaccessible in one go. Disk Doctors are on hand to offer Hyper-V data recovery, with potential solutions in as little as 24 to 48 hours.
Common Causes of Hyper-V Data Loss
There are several issues that can lead to Hyper-V data loss. Cluster Shared Volume corruption can occur due to unexpected host crashes, power loss, or storage connectivity issues, while a failed checkpoint merge can leave a VHDX chain in an inconsistent state. RAID or SAN failures underneath the CSV, such as multiple disk failures or a failed RAID rebuild, can take an entire volume offline.
Accidental deletion is also a common cause, whether that's a deleted virtual machine, an accidentally removed CSV, or a VM mistakenly excluded during a live migration. A failed cluster failover can interrupt access to shared storage, while ransomware and malware can encrypt or delete VHD/VHDX files stored on a volume. ReFS metadata corruption and failed Hyper-V Replica jobs can also leave virtual machines unrecoverable without specialist help.
Our Data Recovery Process
Our data recovery process is secure, transparent, and designed to minimise downtime. Here's how it works:
Send us your device using the free postage label and our engineers will assess it for free. We'll let you know exactly what's recoverable before you commit.
We create a full, bit-by-bit clone of your storage media to preserve the original. Your data remains untouched while we work on the image copy.
Depending on the fault, we use cleanroom hardware repairs or forensic software tools to extract your data, even from damaged or encrypted media.
You'll receive a file list of everything we can recover. Once approved, we'll return your data on a secure USB drive or via encrypted cloud transfer.
Corrupt or Inaccessible Hyper-V Files? We Can Help!
The Disk Doctors team specialise in virtual environment recovery, including standalone Hyper-V Server hosts, Windows Server Hyper-V roles, and Failover Clustering environments running Cluster Shared Volumes. When files become lost due to CSV corruption, a failed checkpoint merge, or an unrecognised volume, our experts use advanced techniques to restore the data. We'll start by diagnosing the cause of data loss, which could be anything from NTFS/ReFS metadata corruption to a failed RAID rebuild or a deleted virtual machine.
Our engineers work at both the hypervisor and guest file-system level. At the hypervisor level, we can repair damaged CSV metadata, rebuild corrupted VHD/VHDX headers, and reconstruct volumes affected by RAID or SAN failure. At the guest level, once a virtual disk has been repaired or cloned, we mount it to recover the individual files, databases, or applications stored inside. If a VM was deleted or a volume reformatted, we can also carve recoverable VHDX and checkpoint files directly from the underlying storage.
Preventing Data Loss in Hyper-V Environments
While the Disk Doctors team can help with Hyper-V data recovery, it's best to prevent data loss altogether wherever possible. Regularly back up virtual machines using Hyper-V-aware backup software, and avoid relying on checkpoints alone as a long-term backup strategy since a failed merge can put the whole chain at risk. You should also monitor the health of the RAID or SAN storage underneath your Cluster Shared Volumes, although we can help with RAID recovery or NAS/SAN/DAS recovery if you do lose data.
Disk Doctors can also help with hard drive recovery and VMware data recovery, with fast and affordable solutions tailored to your data recovery needs.
