Samsung 850 EVO SSD's - Unable to Format

Hello,

So, I had a system setup in a Legacy mode for my gaming machine. The storage included one regular Hard Drive for Windows, and two Samsung 850 EVO's running in RAID 0, running on a Gigabyte Z170N Gaming 5. A week ago, the power died in the house and upon restart noticed that in my Intel Rapid Storage Manager that the RAID had failed. However, there was no sign that the disks themselves had failed, and that it was simply a memory error of some kind. After all, the RAID 0 had the page file on it, so it was going to be necessary to reinstall Windows regardless of what recovery attempts I made.

I decided this time to try and load Windows 10 as a GPT partition in UEFI as opposed to Legacy with a MBR. I have since tried every possible method, from tons of posts on this forum and others to bring the SSD's back online, including changing their ports, formatting them externally and the like, and still have no luck.

In the BIOS, I can only find the disks when the Storage Controller is set to Legacy mode and the Intel RST Premium option is enabled under Peripherals. I thought, "Great! I can load up Gparted, format them, and then reinstall and will have my RAID array back." However, I was soon disappointed to find out that the disks did not show in any bootable Format tool I tried, neither in Windows, in Samsung Magician, or Intel Rapid Storage tools running in the OS. I have tried reinstalling windows on a AHCI Storage mode as well (which was incredibly slow and took almost two days to complete) and still no dice.

I still firmly believe that the SSD's are not broken, and that there is some sort of Parity problem, or other strange error that I am not thinking of. Can anybody here help me figure out a method to reformat the drives?

Thanks

Solution
the problem is either with the MB/BIOS or with the disks.
1. Make sure you have deleted the disks from the raid and disabled the raid. controller might still think they are part of the RAID.
2. try to connect the disks to completely other SATA ports. not those 6 grouped near the 24pin.
3. try the disks in other computer.
