The only sure way is to replace the board with a working one, and reconnect the drives. 

The other option would be a data recovery service, but that will likely cost twice or more what a replacement board would, and recovering data from a striped array is never a sure thing. 

Hi @Clementaod welcome to this free user-to-user Alienware laptop discussion forum. 

Support for Alienware m17 R3 Windows 10, 64-bit or Windows 11 says Storage slot interface accepts M.2 2230/2280 PCIe Gen3 x4 NVMe SSD cards.  

Get loan of (any make) PC (Laptop, Desktop, Workstation, etc,) with identical Windows operating system (BIOS), two M.2 2230/2280 NVMe slots and install both your NVMe RAID SSD cards to plug and play.

With full access to your data, time to decide what to do next. Clone (copy) to single NVMe drive within fast USB-C external enclosure, store data in the internet cloud, etc. 

Just out of interest, is there an existing or proposed replacement PC? 

Hi , thanks for the advice . I have just build a custom pc but I guess it only have 1 m.2 slot . I have order a pcie m.2 adaptor to try plug it in to read have yet to come . But what what I read there slim chance as the array was build with the Alienware motherboard so accessing it might be a problem . As I purchase it from sell it come with raid 0 and win 10 but I update to win 11 . Will it still work with my new pc with win 10 ? 

Hi @Clementaod thank you for sharing additional information. 

Getting access to any PC with BIOS for Windows 11 and two internal M.2 NVMe drive slots for RAID 0 is ideal. 

What external two M.2 NVMe slots RAID 0 adapter has been purchased? Yes, it should work with any make of PC. 

Having updated your drives for Windows 11 get an external enclosure with two M.2 NVMe slots because RAID 0 data is shared 50%-50% across both M.2 SSD drives. The external enclosure's USB-C (or USB-B) cable is then connected to the host computer that has Windows 10 after it has been powered‑on. This will provide access to the RAID 0 data. 

i have plug in my 2 nvme. but in my new pc bios is showing 1 nvme but when in window it show 1tb but asking to format before i can access the drive which interm will wipe the data. 

I am now using a AMD cpu instead of a intel cpu. How do i set it up to read the array?

Hi @Clementaod thank you for sharing additional information. 

Installing the dual drive RAID 0 should have been automatically detected by BIOS, irrespective of using an AMD CPU instead of an Intel CPU. The BIOS MAIN page should report installation of two drives, but the windows operating system should boot into a single RAID 0 dual drive. Something is not working as intended. 

Please check that BIOS menu setting has RAID option enabled. 

Please reseat both drives so that BIOS menu reports that both drives have been installed. If BIOS fails to acknowledge two drives, then one of the drives could be damaged and recovery requires specialist attention. 

I have enable nvme raid in bios and bios did detect the 2 nvme but when I boot using them it just a black screen with _ and when with another ssd for window it still show the e drive but ask me to format when double click as it’s a raw file 

There is also a change that it is Bit Locker protected and where are you located can maybe advise somebody close to you to assist.

If you have a hard drive or any other form of media to use on an intel based system you may be able to use IRST from intel to check on the NVMe drives.
