VHD stands for virtual hard disk, popular file format of Hyper-V hypervisor which is used to store the data over virtual hard disk drive but it is also prone to virus attacks, damaged storage media, hard disk failure, damage of HDD partition and etc. It enables running both 32-bit and 64-bit x86 OS on a single machine and is actually similar to the logical disk in context to booting, adding files and folders, formatting with file systems and etc.
No, the Hyper-V hypervisor already tried to perform an auto-repair if it detects a corruption in VHD file. But, this is not always be possible. VHD file is made up of a hard drive footer that contains the information about the disk, like size and geometry and data blocks. If the disk is dynamic, there is a dynamic virtual hard disk header.
There is a mirror copy of the footer for the dynamic disk at the start of the file. If by somehow, footer get corrupt, then the mirror at the start of the file automatically restored over the footer and used. If the disk is fixed or if the mirror is also corrupted, then no other way exists to perform the repair. The only step possible is to restore a VHD backup. No manual steps are available that can take to solve this type of corruption rather than VHD restore.
If the data block data is corrupt, then run disk repair tool within the virtual machine like chkdsk and try to repair and recover data. The same action you would take if there were problems on the physical machine.
The support of VHD file has been deeply integrated throughout Windows 7. Users can create a system backup of VHD file and also boot from a VHD file. And if you are looking to edit VHD file and make a quick change or pull a file out of the backup, then it can be easily done in Windows 7 and you can easily mount VHD file for Offline modifications in Disk Management.
Steps to create VHD file in Windows
Yes, the software will help you to mount & explore .vhd file contents. From the error message, it seems that VHD file is corrupted. Download and run the demo version of the software that will scan VHD drive and allow to preview recovered VHD data from corrupt virtual drive.
The tool has been designed so that VHD file can be easily read when corrupted, which fails to start with the native application like Hyper-V. You can opt the trial version which will give you clear ideas about the status of the file recovery process from the corrupt virtual drive .vhd file.
Yes, the software supports AVHD Recovery and allow you to restore the files from corrupt .avhd and .avhdx files safely. The "A" in AVHD stands for Automatic i.e. Automatic VHD which is managed by Hyper-V and act as an Automatically Managed VHD. An AVHD or AVHDX virtual drive file is a differencing disk which is actually a child of another VHD or VHDX file.
Yes, you can recover and restore unlimited VHD files from virtual drive as it is a tested utility which has the capability to recover files from more than 40 TB virtual hard disk.
Yes, the tool supports the VHD recovery from any Windows OS server. The application can be easily accessible on all Windows OS edition to implement the recovery process of VHD Hyper-V files.
