VHDX Windows 8 Hyper-V 3.0: Hyper-V (hypervisor) is a virtualization service, and introducing the change old VHD format with the new version under the name VHDX in Disk Management.

Some of the benefits:

  • 1.) - Old Hyper-V VHD only has a capacity up to 2 TB, the VHDX 64 TB.

  • 2) - Protection against data corruption due to power failure.

  • 3) - Better virtual formats alignment on hard disk.

  • 4) - Offers optimum performance on hard drives of large capacity.

I did it so:

  • 1) - In the search box (band right) (or Windows key + R), I introduced diskmgmt.msc command.

  • 2) - In Disk Management appeared, I clicked on Action, in the top menu bar.

  • 3) - Here I clicked on the link Create a Virtual Hard Disk.

- In the new window, I introduced the route for save, and the size of 10 GB, because it proved to be enough, but it can be higher, up to 64 TB.

  • 1) - In the same window, I checked radio button Create Vhdx virtual hard disk.

  • 2) - Finally, I clicked OK.

  • 3) - In Disk Management with black stripe, indicated as unallocated, uninitialized disk.

- To take effect, I restarted the computer. (Vainly clicked on VHDX file saved on drive D:\, appears error message "the disk images not initialized").

After reboot:

  • 1) - In the search box (band right) I introduced diskmgmt.msc command again.

  • 2) - Appeared Disk Manager and immediately, in a separate window, provided the disk initialization.

  • 3) - I did not change anything, just click OK.

- But that's not enough. It should be indicated as volume, and must be formatted as real drive.

  • 1) - In Disk Management, click with the right mouse button, on the black band on virtual disk, and from the pop-up link I chose New Simple Volume ...

  • 2) - Appear three - four windows of information at a time, but I only clicked on Next and then Finish.

  • 3) - Black stripe changed to blue, indicating that it has been selected as a primary partition.

  • 4) - Click on the blue band with the right button of mouse and choose Format link.

  • 5) - A window indicates that all data will be deleted. I ignored because, currently, no data on virtual disk. I clicked OK.

  • 6) - With this done. I close Disk Manager.

Summary: From the above description shows that:

  • 1) - The computer must have at least two partitions (Division disk).

  • 2) - VHDX virtual disk can not be saved to C:\, combined with the installed system.

  • 3) - If you have created a virtual disk VHDX, you must restart the computer to take effect.

  • 4) - Initialization will be offered automatically.

However, it is not enough:

  • 5) - It should be marked as "New Simple Volume".

  • 6) - Be formatted in NTFS format.

Finally, if you open Computer on the Desktop, beside the other will be the "new volume" as a virtual drive, which has the same parameters as any other drive partitioned, with the advantage that if we need it, after saving stored data, simply delete (in this example, from the drive D:\).
