DiskPart Troubleshooting: How to Fix 'Extend Volume Greyed Out' with AOMEI Partition Assistant

China, 10th Sep 2024 - The "Extend Volume" option in the Disk Management tool is only accessible if there is contiguous unallocated space located behind the volume you wish to extend. Unfortunately, the "Extend Volume" option is not available because there is no unallocated space after the C partition drive. We require a vacant space located at the rear of the goal partition (drive: C). In theory, it is possible to shrink the volume of drive D to create unallocated space. However, it is important to note that the unallocated space will be located behind drive D, rather than drive C. Unfortunately, it is not possible to move the unallocated space.

To resolve the issue, the only solution is to delete drive: D, which will result in the loss of all data stored on it. In order to prevent that, it would be wise to make a backup of the D partition beforehand. However, this will require a significant amount of your time. Many users are searching for a more efficient solution to bypass the issue of "extend volume greyed out" without losing any data or wasting too much time.

Actually, if the "Extend Volume" option is grayed out, you will need to delete the file next to it to make room for it. It is important to know that all the data on the partition will be erased forever before you continue with this operation. Because of this, it is strongly suggested that you back up any important data first. It is suggested that you use AOMEI software if you want a faster way to handle backups and safely increase partitions without losing data.

Before you do:

1. If there are programs going on the partition, AOMEI Partition Assistant will tell you to shut them down or do the work in PreOS Mode.

2. The data section and the system boot drive can be joined together, but not the other way around. It was not possible to merge the "System Reserved" section.

Third, you can only join two partitions next to each other at a time. On the other hand, you can turn any empty area into a partition.

Step 1. Install and launch AOMEI software. You can see there is unallocated space next to the drive on the main interface. (If there is no unallocated space, you can use Resize/Move Partition to get unallocated space)

Step 2. Right-click the target drive and hit "Advanced" > "Merge Partitions"

Step 3. Choose unallocated space, and then click OK.

Step 4. Click Apply, you will see the target drive (C drive as the example) has been extended.
