How to Access RAID1 Storage on Dual Boot with Windows and Linux?

Asked By TechWanderer92 On

I've recently set up Nobara 43 with KDE and everything's been great so far except for one issue with accessing my RAID1 storage. Here's my setup: I have a 2TB NVMe SSD for Windows, a 1TB SATA SSD for Nobara, and two 8TB HDDs in RAID1 configured through the ASUS ROG BIOS. While I can easily access my Windows files from Nobara, I'm unable to access my RAID1 drives, which contain all my important documents, pictures, and media. I've read that the RAID1 setup in the BIOS is considered software RAID and may only work with Windows. I'd like to know how I can use these drives for data redundancy while making them accessible from both operating systems. I'm not opposed to investing in a physical RAID controller if necessary, but I'd prefer a solution that doesn't involve extra costs if possible. Any advice or alternatives?

It seems like your RAID1 setup is showing up as a single device in Windows, which is a common behavior for BIOS-based RAID configurations. However, in a dual-boot scenario, the accessibility of that RAID from Linux can be tricky. Generally, BIOS RAID can be recognized by Linux as long as the correct drivers are available. If you want full access from both OSes, consider switching to a software RAID setup using Linux's mdadm, or potentially a dedicated hardware RAID controller, but that will require data backup beforehand.

It's a bit of a mixed bag when it comes to accessing that BIOS RAID from Linux. If Windows sees the two drives as a single entity, then they might be using a proprietary driver that doesn't translate over to Linux. You'll want to see if Asus has any support for Linux on their RAID setup. Alternatively, if nothing else works, you might have to transition to a more conventional setup like mdadm in Linux to manage the RAID, but that will mean emptying the drives first to avoid data loss.

For your dual-boot setup, the RAID1 you're using sounds like it's a bit of a hybrid system, which can complicate matters. The BIOS RAID (also known as "fake" RAID) might need specific support from Linux. You could look into whether there are any Asus RAID drivers compatible with Linux. If your Windows and Linux installations aren't recognizing them the same way, it might lead to issues accessing the drives across both systems. If all else fails, investing in a true hardware RAID solution could simplify your life, as it doesn’t require software drivers and generally offers better compatibility.
