  • Hi,
     
    If the unallocated space is adjacent to the drive that you want to merge. You can add more space to the drive by extending them into adjacent unallocated space on the same disk.
     
    For more detailed information, please refer to the article below:

    If the unallocated space is not adjacent, you may need a third-party partition tool like "partitions wizard".

    Using third party softwares that do that without losing data, actually all partition editors softwares can do that, but from windows it's not possible to extend without losing data.
     
    But make sure that you have proper backup restore procedures in place before performing the change.

  • Hi, 

    As Mandy mentioned, Disk Management of Windows Server 2008 R2 features "Extend Volume" which allows you to extend a drive into contiguous unallocated space (on the right). For example, [C Drive][D Drive][Unallocated Space], in this case you can only merge unallocated space to D drive. Just right click the D drive and select "Extend Volume". Then, follow the wizard to add unallocated space to D drive.

    Take the above example, if you want to merge non contiguous unallocated space to C drive, there are two solutions, learn more: http://www.partition-magic.org/res/merge-unallocated-space-to-c-drive.html
