My motherboard is an MSI Big bang xpower with a RAID 5 running Windows 7. The ICH10R on the motherboard controls the RAID. Recently a power interruption occurred and the RAID was not able to complete a verify operation - instead of completing, the verify stopped at 77%. Then a drive reported a smart event. I removed the drive with the smart event to analyze it in another computer. When I replaced the single smart event drive into the original computer and restarted that computer, the RAID 5 array failed completely.
The ICH10R in band raid utility says I still have three good drives, so why has the RAID array failed? I can't seem to make the setup recognize the failed drive to reset the smart event either. My most recent backup is three weeks old, and it would be nice to recover the volume if possible. Any ideas why the RAID has failed with 3 of 4 good disks?
