    Help merging "Disk2" (931 GB) to "OS (C:)" (117 GB)


    PC Info:
    (Laptop) MSI GS60 2PC
    Intel Core i7-4710HQ CPU @ 2.5 GHz
    Currently running "Windows Embedded 8.1 Industry Pro" obtained legally from Microsoft Dreamspark
    Windows 8 is the native OS for my laptop

    Problem:
    I am trying to merge Drive 2 (unallocated, 931 GB) and return that memory back to the OS C: partition where it belongs.

    Context:
    Fairly recently, I upgraded to Windows 10. After upgrading, the overall performance of my pc was sluggish, which I think is because Windows 10 isn't the native operating system. Please correct me if I'm wrong though. Anyways, I switched back to Windows 8.1 without any problems. In the past couple of days I noticed that my hard drive had been split in two: Disk 1 being the main OS; Disk 2 used for recovery data. Knowing that I didn't need the recovery data anymore I wiped Drive 2 and am currently puzzled in figuring out how to return the 900 GB of data to the OS partition. I have tried more basic attempts such as, trying to extend the OS partition and select Drive 2 as the selection to be merged (didn't work probably for obvious reasons I'm unaware of). I have also installed "Mini Partition Wizard Pro" but still am running into the same problems.

    Someone used an axe? Looks like 2 different, independent drives. I'd keep it that way, one for os\programs and the other for files\storage (just format it, job finished). Normal extension is not possible between different physical disks. Alternative would be to wander into the world of dynamic disks > What Are Basic and Dynamic Disks? Features for Dynamic/Basic Disks (but am not recommending playing with this...)

    LMAO yes, exactly. I don't recall it being that way before. It wouldn't make sense that it was, but I'm no computer expert. Anyways, I put it as storage. It was such a simple solution that I didn't even think to do that.

    I read about dynamic disks but I'll just leave it at that.

    Yes you actually do have 2 physical drives they are set up correctly, you did the correct thing by formatting your 2nd hard drive to use as storage.
