    Clusters Per FileRecord Segment : 0
    Mft Valid Data Length :           0x0000000008000000
    Mft Start Lcn  :                  0x00000000000c0000

  • There is no way to change that without reformatting, at least not with Windows onboard tools.

    I believe that some 3rd party tools allow you to do that like PartitionMagic & alikes. But i would not guarantee that you won't loose any data.

    The safest way would be reformatting.

    1) Make a decent backup

    2) Verify created backup

    3) Wipe original volume off

    4) Format ex-volume with a new block size

    5) Get data back from backup

    That's the most desirable way to go. With a built-in tools. For third-party ones check Acronis, they used to be able to do it (last time for a free space only) and MiniTool from a Partition Magic also did it (but not with a free version of the software AFAIR). 

    Good luck :)
