So I have a RAID0 array set up using 2 drives using btrfs file system. It works fine under Cachy.
There is a driver available for Windows that seems to work well with any single drive. However, it does not recognize the btrfs RAID array. Does anyone have any ideas on a possible workaround to make the RAID array visible in Win 11?
Not sure if your Intel based or AMD, details matter.
Install Storage Controller Drivers If the RAID array does not appear in Disk Management or File Explorer, the operating system likely lacks the necessary driver to communicate with the hardware.
Intel RST: For Intel-based systems, download and install the latest Intel Rapid Storage Technology (RST) driver from your motherboard or PC manufacturer’s website.
AMD RAID: For AMD systems, ensure the AMD RAID Driver is installed.
After installation, restart your computer.
The array should now appear as a single drive in Device Manager under “Disk Drives.”
The drives do show in Disk Management. I was worried that the Windows RAID driver might break the array from working in CachyOS. Any thoughts on this? I guess I can copy the data to another drive for the time being to test and if needed, I can just set up the array in CachyOS again.
And I forgot to mention it, but it’s an AMD setup on an MSI B55 Gaming Edge Wifi mobo.
Thanks for your feedback!
Sorry I have not used windoze since 2007, but it should not break any thing, and back-ups are mandantory for peace of mind. 
Let us know though if things go south on you.
The data on the RAID array is trivial in the end. I mean, I don’t want to loose it, but at the end of the day, it’s all replaceable over time.
I’m going to give it a shot! I’ll post an update when I do. It may be a later tonight though.
Ok so I gave it a shot. The driver’s installed fine. I had to initialize the disks as GPT, but the RAID array still isn’t accessible via Windows. Oh well, not a huge deal. I barely use Windows. It was more of a convenience than a necessity. I did contact the WinBtrfs devs via github to see if this can be added to a future version.
OH and it did break the array when I initialized the disks, and technically I forgot to put the BIOS in RAID so that may be an issue too.
