Our VHD & VHDX Recovery Approach
VHD and VHDX failures typically occur after a crash, storage issue, failed checkpoint merge or an attempted repair.
If your virtual disk won’t mount, won’t attach, shows as RAW, or the VM won’t boot, we start with read-only triage to prevent further damage. We then pinpoint 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 sits on unstable RAID, NAS or SAN storage, we can stabilise and recover the underlying media first to avoid compounding the loss.
Common VHD & VHDX Problems We Fix
The underlying RAID, NAS, SAN or drive is degraded and the VM is down
The disk shows as RAW or unallocated after mounting
A backup, replication or copy was interrupted and the VHDX is inconsistent
The VHD or VHDX is deleted or emptied
The VHDX will not mount or attach in Hyper-V
The VM will not boot after a crash or power loss
A checkpoint or AVHDX merge failed
The 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 won’t 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 a single virtual disk and the VM is down, see our Hyper-V data recovery service.
