A BIOS update not only updates the BIOS code, but also other units that are in communication with BIOS. And one fo these units is Intel's AHCI ROM. Intel AHCI (Advanced Host Controller Interface) ROM can be found on motherboards with Intel Chipset and it controls SATA ports and RAID setups with an onboard Firmware.

But as we have told, BIOS Update sometimes updates the Firmware of Intel AHCI ROM. But this usually breaks the RAID 0 Array suddenly without any warning. After that, you get "Array Failed" errors. The worst part is what Intel says for those situations: "If you were using RAID 0, say goodbye to your data."

You know that all data is on the disk. Nothing was actually removed. It is just a stupid error that prevents you from reaching your valued data but where is the gimmick? Maybe a code change, a small low level tocuh to the Hard Drive Sectors...But you don't know how and it is very complicated.

The first time I had this problem, I wasn't able to recover all the files perfectly. But the second time when my friend had this problem, I thought it was about time that I investigate deeper and come up with a better solution. I won't take your time any longer. Restorer Ultimate, R-Studio and RAID Reconstructor are the best tools for recovering data from failed RAID 0 arrays. But I have discovered the most easy and the fastest one: RAID Recovery for Windows!

I have secured 2.7 TB of data from 2 x 3 TB RAID 0 Array.

Here is how:
The first thing you need to do is know which disk is the first and which one is the second disk of the RAID 0 Array. You can check this at Intel Rapid Storage Tool. Look for serial number endings of the disks. Boot into BIOS and set SATA Mode to AHCI rather than RAID. Now boot into Windows. You should see disks are seperated now. Download RAID Recovery for Windows and run it. Choose the first disk and then the second. Click Next. A page conatining all the Info about your RAID 0 setup will appear, just like below:


Now click on Finish to mount the file system. You should see your data inside the software. Now all you need to do is buy the software for $99 and save your data. It took me 18 hours to save 2.7 TB of data. 40MB/s to an external USB 3.0 hard drive. I hope you get your data back too. Please share if it helped.
