    Lost RAID after PC reboot - Win7 Pro 64bit RAID 1


    The computer has been fine for around 2 years, never an issue. About an hour ago I reboot the machine and instead of having my RAID 1 as my C drive, I now have two identical drives, the C drive and the H driveas well as an F drive.

    How do I get them back to where they belong?

    In the BIOS SATA is still set to RAID, and I admit that I didn't do the raid config. I am assuming it was RAID 1 because both drives are still working, just working separately instead of as one.

    Any suggestions?

    Windows 7 Pro 64bit

    Edit: The after checking Disk Manager, there's no failed drive, not even a drive listed as a mirror etc. Just new drives that don't belong.

    C: and H: should be the raid array. F drive is something I am not sure about.

    The F drive contains: BOOTSECT.BAK, bootmgr Sytem Volume Information, Boot folder, and $Recycle.Bin

    The H drive has some things in it's root that should be on the C: and the C drive has some things left but is missing the files found on H.

    I'd like to put these back into the raid array. I am just not sure how to proceed without a complete wipe.

    Does anyone know how to create a RAID out of the two drives without loosing everything? I'm still not sure where this F: came from, seems like a piece of the raid array became a partition or something.

    I'd like to get my RAID back, but I've only ever done it when I first build a system.

    Was the raid through your motherboard, as in hardware raid vs windows (software raid)? If so it looks like your array dropped and that is not easy to fix without blowing it all out and making a new array in the config for the hardware. Can you list your mobo model please.

    The F: drive appears to be the System reserved partition that normally does not have a drive letter assigned.

    What model ASUS motherboard do you have?
