Windows 8 (or rather Windows Server 2012) introduced a new file system called ReFS. ReFS stands for Resilient File System. Codenamed "Protogon", it improves on NTFS in some respects, while also removing a number of features. You may read about the advantages of ReFS in the following Wikipedia article. ReFS is intended for file servers only. In Windows 8.1, it is in fact locked for server OS only. If you need to unlock and enable full read and write support for ReFS in Windows 8.1, you can follow these simple instructions in this article.
To enable support for ReFS,
- Open your registry editor (see how)
- Navigate to the following registry key:
Tip: you can access the desired Registry key with one click.
- Create here a new key called MiniNT to get the following path:
- Here, you should create a new DWORD value called "AllowRefsFormatOverNonmirrorVolume". The value data of this parameter must be 0 or 1. Set it to 1 to unlock the ReFS feature in Windows 8.1.
- Reboot your PC.
That's it. Now you will now be able to write to ReFS partitions, format new partitions in ReFS and so on.
Bonus tip: To create an ReFS-formatted drive, you can perform the following steps.
- Press Win+R keys on the keyboard. The "Run" dialog will appear on the screen.
- Type diskpart and press Enter. Confirm the User Account Control request.
- Select the disk you want to format with the following commands:
list disk sele disk 6 clean create part pri format fs=refs quick
Note: 6 is my disk number which I want to format with ReFS. You should specify the correct disk number depending on what you see after doing 'list disk'. Also note, this operation will remove everything from that drive.
