Windows 10: RAID 1 Recognized as 2 Hard Drives

    RAID 1 Recognized as 2 Hard Drives


    My custom build is now about a year old. Whe n I first set it up, I configured hardware RAID 1 and the fresh windows install worked perfect. Now after a few upgrades the drives are not seen as a RAID anymore but 1 separate drives.

    Funny thing is when I mounted on a different OS, the RAID is seen fine and in synch, no issues.

    Anybody know how to tackle this one?

    Hi there.

    Is the RAID driver recognised - with all these W10 updates who knows what happens.

    If it's a Hardware RAID card then check BIOS setting at boot. Also there will probably be some sort of RAID boot menu - for example setting up Logical drives / striping etc etc.

    If it's software ensure RAID driver is recognized.

    The chances are that Windows doesn't recognize the RAID card so that's where I'd start from. Backup though data on the RAID HDD's first because a suggestion would be to unplug the RAID card and re-insert again after a total POWER OFF. If you can put it into a different slot. You want Windows to recognize the hardware.

    Before doing these types of updates I'd always image the system - things like Macrium are ideal for that. Then if the update hoses up your system just restore the previous image.

    Are you sure you have a "hardware" RAID setup? For this type of RAID you have to buy a "Hardware" controller card....and those are not cheap. See link......

    If you mobo has a built in RAID controller (it's a lie).....it's just software RAID as the cost of the mobo would be much more expensive.

    Hi there.

    A clue is that the OP has used it with different OS'es - so I suspect it must be a hardware raid but an addon card.

    Very few domestic Mobos or even enterprise grade NON SERVER Mobos have built in RAID controllers -- usually people buy add on cards or use Software RAID.

    So the first thing to look at is that if it's an addon card see if Windows recognises the hardware. If it doesn't - problem solved - or it might just see it as another SATA controller for standard HDD's.

    I can't see what Software RAID buys these days as on W10 you can use Storage spaces (been available since Windows 8) to achieve the same object and what's more you can use different sized HDD's too. but that's another issue.
