A disk image file is an exclusively designed file that contains the structure and contents of a disk volume or complete hierarchy of a storage device such as HDD, floppy disk, USB drive, etc. A disk image file flawlessly mimics data of storage devices by creating a sector by sector copy of the source. Also, the content or data of the image file is independent of the file system.
As disk image files are present on the host system which are also seen by guest computers as physical hard disks of a specific structure. If a guest computer reads to/writes to the physical hard disk, it redirects the request to the image file with the help of virtual environment. A virtual disk is similar to a physical disk and it is created with specified storage when the image file is created.
Now, let’s do a detailed study on two major file formats -VHD and VMDK. How they are different? What are the important features? What are their advantages and limitations?
The VHD file is Virtual Hard Disk file that clones or contains the data of a physical hard drive like files and folders inside disk volume partitions. A VHD file is traditionally a Virtual Machine hard disk. It was developed by Connectix for a product named Virtual PC. Later Connectix was acquired by Microsoft in 2003 and named it Microsoft Virtual PC.
The benefits of using VHD files are as follows:
A VMDK file format is the container of Virtual Hard Disk drives that are used by virtual machines such as VMware Workstation and VirtualBox. A VMDK is a disk image file that was developed by VMware for their own virtual products. These files are accessed, and its size grows when they are used by VMware’s Virtual Disk Manager.
Although, both VHD and VMDK file formats are for virtual environments and possess their own level of limitations and advantages for a user.It becomes a tedious task for a user to recover Lost or Deleted VHD & VHDX Files and VMDK files. Therefore, we recommend using third-party tools offered by Kernel Data Recovery, that can make the process of recovery easy and time-saving. You must try these two tools for VHD Recovery and VMDK recovery named as Kernel for VHD Recovery and Kernel VMDK Recovery Software.
