Our VHD and VHDX Recovery Approach
VHD and VHDX failures typically hit after a crash, storage issue, failed checkpoint merge, or an attempted repair.
If your virtual disk will not mount, will not attach, shows as RAW, or the VM will not boot, we start with read-only triage to prevent further damage. We then identify the corruption point and recover what you actually need, either extracting files and folders or rebuilding the VHD or VHDX so the data is usable again.
If the VHD or VHDX lives on unstable RAID, NAS, or SAN storage, we can stabilize and recover the underlying media first to avoid compounding the loss.
Common VHD and VHDX Problems We Fix
Underlying RAID, NAS, SAN, or drive is degraded and the VM is down
Disk shows as RAW or unallocated after mounting
Backup, replication, or copy was interrupted and the VHDX is inconsistent
VHD or VHDX is deleted or emptied
VHDX will not mount or attach in Hyper-V
VM will not boot after a crash or power loss
Checkpoint or AVHDX merge failed
VHDX reports “incorrect format” or “file is corrupted”
VHDX performance is extremely slow and then fails to open
Do not run repair tools and do not mount or write to the only copy of the VHD or VHDX. Any write can reduce recovery odds. Request help to review your case now.
What We Recover From VHD and VHDX Files
We recover business-critical data stored inside VHD and VHDX virtual disks, including Active Directory (AD DS), SQL Server databases, and file shares with folder structures and permissions where possible.
We also recover user profiles, application data, shared departmental folders, and other production datasets that teams rely on to operate. This includes cases where the disk will not mount or attach, shows as RAW, was accidentally deleted or overwritten, or became inconsistent after a crash, checkpoint activity, or storage errors.
If the incident extends beyond one virtual disk and the VM is down, see our Hyper-V data recovery service.
