Windows 10: Drives C and D showing up twice -- as K and L

    Drives C and D showing up twice -- as K and L


    Hello. I was automatically upgraded from Windows 8.1 last night to Windows 10 (64 bit). My main drives C and D are now showing up twice in Windows Explorer -- as K and L. This is confusing the heck out of my backup tool. How do I get rid of these second instances? The drive is RAID 1 if that matters.

    By the way, the suggestion elsewhere to remove the two DelegateFolders keys in the registry did NOT work. I rebooted twice.

    Thanks for any help at all.

    Hello bvy, and welcome to Ten Forums.

    You can use an option in the tutorial below to remove the duplicate drives in the navigation pane.

    Thanks for the Welcome! Yes, that link is the DelegateFolders tip and it did not work for me.

    After further review, it looks like the upgrade broke my RAID configuration. Is this a known issue? I can't find anything on this.

    In that case, please go ahead and post some screenshots showing this in File Explorer and your drive layout in Disk Management to see if it may help reveal what the issue could be.

    Thank you. See attached. As you can see, C and K are the same and D and L -- except, they're starting to diverge now that the redundancy is broken. I tried unsuccessfully fixing this in the Storage Spaces area. BIOS still shows that the drive is RAID enabled. I don't understand how this happened, and I'm not sure how to fix it. Thanks for any help.

    Odd. I'm afraid that I'm not sure how it broke the RAID as well, or how to fix it other than start from scratch. Hopefully someone else may know more for a better solution.

    I would check your Raid Controller is Using the Raid Driver it should (Intel?) and not the Microsoft Drivers , I had many issues on my older Comps. using ICH10R Controllers when upgrading to Win 10 , the Win10 auto installed Driver for them was not fully supporting the Controller properly.

    And also check at boot in the Raid Controller Bios (Ctrl-I (eye) ) to make sure all is well....

    Installing the Intel RST software , if using Intel Raid , may help and allow you to verify Data too in windows.
