Does updating bios remove raid
This also happens when a new BIOS is flashed as it consequently clears defaults.
The raid array shouldn't drop as failed To clear any confusion that I simply forget to set RAID to the controller here are the exact steps I take: Load setup defaults Save and exit bios reboot Delete to enter bios Set controller to Raid, disable CSM Save and exit bios.. If I look at the Raid array it shows as failed, having only one member while the other disk shows as not a member. Sometimes both show as failed with one member missing and sometimes only my UEFI-boot Win8.1 array shows as failed.I'm sorry about my English : D, you are correct, only changing data mode from AHCI to Raid after a reset, but since you're doing that then I see you're problem, it's really strange. Looks like my issue isn't unique as there are more cases popping up : Issue must be identified and resolved, any more information needed I will be happy to provide Motherboard model: Asus Rampage V Extreme UEFI Version: 0801 CPU: Intel Core i7 5960X 4.5ghz 16gb Corsair Platinum 2800mhz GPU: TITAN Black Tri-SLI SSD/HDDs/Optical drives: 850 Pro x 2 Raid 0 | WD black 1.5TB x 2 raid 0 | WD black 2TB x 2 Raid 0 | Samsung XP951 M.2(boot drive) PSU: AX1500i USB Devices (model/version number): Razer Blackwidow | Razer Ouroboros Monitor: ASUS ROG Swift PG278Q GSYNC | CPU Cooler: Custom Watercooling loop PC CASE: Corsair 900D Sound Card: Asus Xonar Essence STX Operating system: Windows 8.1 Enterprise Drivers Installed (include version): latest drivers on Asus support page.
