    Raid 1 setup in windows 8.1. missing hard drive


    Hi! I am having trouble setting up a raid 1 (mirror) on a new computer using two identical hard drives. I have tried several things that I have found online.
    My system has an Asus motherboard A55BM-plus with an amd fm2 processor. Bios is set to a raid configuration and the bios sees both hard drives (two Seagate 500 gb). All equipment is new.
    Device manager shows both hard drives. Device mgmt. shows only drive c. and my dvd rom.
    Any advice would be appreciated. I am by no means an expert. I just love playing with computers.

    I do believe if they are mirrored Raid 1, you'll only see one drive in Explorer and disk management. As far as Windows is concerned there is only one 500 GB drive. The controller does the simultaneous reads and writes to both drives in the background. If one drive fails the controller just limits access to the one good drive. If you had done a striped array, RAID 0, you would see just 1 1 TG drive in explorer and disk management. Device manager knows there is two drives as that's the actual hardware connected.

    Hi there

    FORGET RAID in Windows 8.1 --Use storage spaces instead - much more efficient, and VOLUMES CAN BE OF DIFFERENT SIZES too.

    You can also specify how much % space you want to reserve for recovery area / index too - my gut feel is that 25% is probably MORE THAN ENOUGH for most home users -- I'm totally amazed how this feature added since W8 hasn't been more publicized by Ms - it's a real winner in all sorts of ways and the fact that you can use totally different sizes of volumes in the storage pool should make the word RAID now like a 4 letter word - you shouldn't need it again on a home computer.

    Thanks Caperjack. I had already tried this video but my second drive does not appear in disk mgmt.
    Thanks alphanumeric. How do I check drive 2 to see if my info is there? Drive C, of course, is visible.
    I appreciate all replies!

    You can't, not easily anyway. Drive C is actually the array, it's both disks. I would think if the two drives don't match the RAID controller would throw up some kind of error message to tell you.

    In theory you could unplug one of the drives and see if Windows boots up. That will tell you that the other drive still connected is OK. Then reverse that so only the other drive is plugged in and boot up. You'll likely get a BIOS warning telling you one drive is missing. Also the two drives won't be identical anymore. I'm not sure what happens then when you connect them both back up. If you do this don't blame me if things get messed up. I have never done it myself. I have run RAID in the past but I ran striped arrays for the increased speed. The novelty wore off after having to rebuild the array a couple of times so I gave up using it.
