Extend volume grayed out

  • Contents:

    When system prompts a certain partition is running out of space or there is no enough space to save new files, we believe every user would want to extend the very partition as soon as possible. Therefore, since Windows Vista, Microsoft adds the feature "Extend Volume" to system built-in Disk Management program. But disappointingly, the problem Extend Volume Grayed out often appears, like the following image shows:

    What’s the reason? In this article, we will show users 2 possible factors as well as give corresponding solutions. Note: this article is all about basic disk rather than dynamic disk.

    Reasons for Extend Volume Grayed out

    In one of the following 3 situations, "Extend Volume" will not work:
    1.The partition users want to extend is not a NTFS partition. Microsoft says extending volume feature in Disk Management only works to a raw or NTFS partition.
    2.There is no unallocated or free space on hard disk or the space is not contiguous and after the partition which needs extending.
    3.Users want to extend a primary partition, but there is just a free space right after the target partition.

    Now that Windows "Extend Volume" will be grayed out under these situations, users would want to get some wonderful solutions. Currently, there is partitioning tool which can extend a partition without limitations, and MiniTool Partition Wizard can be chosen.

    Extend Partition with MiniTool Partition Wizard

    MiniTool Partition Wizard can help users extend both FAT partition and NTFS partition no matter whether there is unallocated space on hard disk. Next, let’s take extending a FAT32 partition in Windows 7 for example.

    Firstly, launch the partitioning tool to open its main interface:

    minitool partition wizard main interface select partition to extend

    Then, select the partition which needs extending (here, we extend partition G which is a FAT32 partition, and there is no unallocated space contiguous the partition), and then click the function "Extend Partition" from action panel.

    extend partition choose a partition or unallcoated space to take free space

    Next, expand partition G by taking free space from an existing partition or from an unallocated space and drag sliding button to decide how much space to take.

    extend partition apply change

    At last, apply all changes if they are satisfying.

    After application, the selected FAT32 partition will be extended. Now, download the partitioning tool MiniTool Partition Wizard to solve the problem Extend Volume Gray out.
