I have a PC with an ASUS P8H67-=M PRO motherboard, i5, H67 chipset, and only one add-on board, an ASUS WiFi card. I believe the PC was built in 2011. I have one standard drive for Windows 7 Ultimate 64bit, with latest updates, and three 1 TB drives organized as RAID 5, using Intel RST.
Thinking it was routine maintenance. I updated my BIOS from the original ASUS Ver. 1003 to the latest, Ver. 3904, using ASUS AI Suite II Update (their Windows System Control Dashboard). When I rebooted, the ASUS Update asked me to install the BIOS again using Update. Seemed a little unusual, but I figured it was some kind of bootstrapping problem and went ahead. When I did that, ASUS Update automatically installed all new drivers, including the three drives of the RAID array. Now Windows sees them as three individual drives and does not recognize the formatting. I tried Windows restore to a date before today, but it did not change the BIOS or Drive configuration.
Rather than poking in the dark and making things worse, I'd like to ask the community to please advise what I can do to get my RAID array and its data back.
