You should specify the correct disk number depending on what you see after doing 'list disk'. Note: 6 is my disk number which I want to format with ReFS. Select the disk you want to format with the following commands: list disk.Confirm the User Account Control request. The "Run" dialog will appear on the screen. Now you will now be able to write to ReFS partitions, format new partitions in ReFS and so on.īonus tip: To create an ReFS-formatted drive, you can perform the following steps. Set it to 1 to unlock the ReFS feature in Windows 8.1. The value data of this parameter must be 0 or 1. Here, you should create a new DWORD value called "AllowRefsFormatOverNonmirrorVolume".Create here a new key called MiniNT to get the following path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\MiniNT.Tip: you can access the desired Registry key with one click. Navigate to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control.
