Causes when Extend Volume Disabled in Disk Management

Here is a list of causes when Disk Management cannot extend volume.

• The unallocated space is from another disk
• There is no unallocated space on the same disk
• The drive you want to extend is FAT32 or others instead of NTFS since Disk Management can only expand ntfs volume
• There is other partitions that stands between the drive and the unallocated space, such as the recovery partition or others.
• The unallocated space has not been changed from free space. You need to create a volume on the free space, and then delete it to make the space unallocated.
• The volume has reached the max size 2TB if it uses MBR disk partition style.
• There are active snapshots or shadow copies that prevent resizing of the volume.
• The volume is part of a striped or spanned dynamic disk set
• The disk has write-protection.
