In as you are familiar, Disk Management tool enables us to create, format, delete, shrink and extend partitions without the help of any other tools/ software.  But you might have noticed that when extending, you may see that the Extend Volume option, which appears when you right-click on a partition, it’s either graved out or disabled. The Disk Management may not allow you to extend a partition even if you have unallocated space on your drive.

If the Extend volume option is disabled it might be because of the following reasons.

Reason 1 of 4

You are trying to extend FAT or FAT32 partition

Windows doesn’t support extending FAT and FAT32 files systems out of the box. If you want to extend FAT and FAT32 partition you need other tools and software.

This is how you can check if partition is formatted with FAT, FAT32 or NTFS:

Step 1: Open this PC, right-click on the partition you want to check and then click properties.

Step 2: In the General tab you can see the File System written and right next to is shown how the partition is formatted.

Reason 2 of 4

There is no unallocated space on the drive

You must have unallocated or un-partitioned space on your drive at all times in order to use the Extend volume feature. It doesn’t mean that if you have GBs of space free on one of your drive you can use the space to extend other drives.

Reason 3 of 4

The unallocated space is not to the right of the partition that you want to extend

Let’s say that the unallocated space is after “C” drive and before the “D” drive. So, in this case, the unallocated space is after “C” drive and there is no unallocated space immediately after “D” drive. Because of this, when I right-click on “C” drive/partition, Windows displays Extend volume option. The same option is grayed out when I right-click on “D” drive because the unallocated space is not immediately after the “D” drive. In the picture below, the unallocated space is to the right of the partition “C”, and Windows allows me to extend “C” drive without any issues.

In this situation we recommend the use of MiniTool Partition Wizard free, to extend your partition without any problems.

Reason 4 of 4

The unallocated space is not in the extended partition

If you want to extend a logical drive on a basic disk, remember that the unallocated free space must be in the extended partition that immediately follows the logical drive.

In other word if you are unable to extend a volume or partition using Disk Management please use MiniTool Partition Wizard.
