    Cannot Extend Partition in Disk Man... Stumped.


    Hi all,

    After installing Windows 8 my computer had four partitions; I thought they'd be fine but want to change it to have two big ones, one for Media and one for typical C: usage. I moved everything out of D:\ to delete the volume so I would have free space to the right of C:, which I've read is what you need to do in order to extend partitions using Disk Management. However, the option is still greyed-out when right-clicking C: as shown:

    Click image for larger version

    I did this because I've read mixed things about using 3rd-party software to extend partitions; some that don't truly extend it and just trick your computer into merging the two... I like doing things the purest way possible and would like to truly combine C: with the free space to the right of it.

    Any idea why the option is not available? Thanks much.

    Isn't the green area unallocated space? I deleted the volume that was previously there.

    There doesnt appear to be a free drive available to extend to, the free space you made is on the same physical drive.

    What you want to do is to resize or merge partitions, not extend, extend means to use another, different physical drive to extend to.

    as SIW2 provided a link to, AOMEI is a great partitioning software.

    It is inside an extended partition. You will need to get it out of there first.

    Use one of the 3rd party tools I posted. They both have free versions .

    Ahaaaaaa I see, I think. Well that was silly.

    Using these 3rd party softwares, does it actually rearrange the data on the disk so that the two physical areas that were separate partitions become one contiguous region? Or does it just trick the computer into seeing two regions as 1, even if they are physically separated on the disk?

    How do you mean trick?

    They are excellent partition managers. I use them frequently. I don't know what you have read - most of the stuff one reads on the internet is nonsense.
