Hello everyone, Yesterday, while I had nothing to do I decided to update the whole system with new drivers and stuff. The problem is, I updated the BIOS, too. Updating the BIOS restored all the settings to their defaults, and my data RAID is now gone (didn't have important data on it, just a sh*t load of Steam games and other big files ). I soon searched for a solution, and came to this thread, where a user had this same problem and fixed it like so: I downloaded TestDisk and ran it. This is basically what I did: 1) Selected the Intel Raid 0 Volume 2) Selected Intel/PC partition 3) Quick-analyzed the drive, after about 5 hours it didn't found the DATA partition 4) Fully-analyzed the drive. The software found the DATA partition of 4TB 5) Pressed the enter button, program says: No partition found or selected for recovery The software says the same thing even if I go to the Advanced tab and try to restore from there. The strange thing is, if I select EFI GPT partition and go to advanced, the software immediately finds the three partitions. When I'm there, I can see all of my files and recover them to an external HDD. Thing is, I don't have a 4TB HDD . Quick question: Are MFT and partition table the same things? If I click on "Repair MFT" under Advanced, and then Boot, it says: "MFT and MFT mirror are bad. Failed to repair them." Maybe I'm just not finding the right function to repair my partition table, if so, please correct me and point me to the right direction. P.S.: Please don't start saying "You shouldn't use RAID 0 for any important data" etc. etc. I already said there were no important files in there, just a bunch of big files that would otherwise take a lot of time to download again. Thanks in advance for any reply.
