Why Can’t Extend the Volume Using DiskPart

Why are you unable to extend the volume using DiskPart? According to user reports, the “DiskPart unable to extend the volume” error often occurs when extending a partition with the FAT32 file system. This is because DiskPart can only extend the NTFS or RAW file system.

Besides, if there is no contiguous unallocated space behind the target partition, you will receive the “there is not enough space to extend the volume” error when using DiskPart.

# 2. Convert the Volume to NTFS

One of the common reasons for the DiskPart unable to extend the volume error is that you are extending a FAT32 partition. In this case, you need to convert it to NTFS first and extend it. However, Windows provides no direct way to convert FTA32 to NTFS unless you format the volume. Make sure you have backed up all important data beforehand.

Apart from Windows utilities, is there a way to convert FAT32 to NTFS without data loss? Of course, yes! MiniTool Partition Wizard can help you do that easily.

# 3. Delete the Volume Behind the Target Volume

If you receive the “There is not enough space available on the disk to extend the volume” error using DiskPart, the main reason is because of no contiguous unallocated space behind the target volume. In this case, you can either use a professional partition resizer or delete the volume right behind the target volume. For that:

Step 1. Press Win + R keys to open the Run dialog box, and then type diskpart in it and hit Enter. Then click on Yes to further confirm it.

Step 2. In the pop-up window, type the following commands in order and press Enter after each one.

  • list volume
  • select volume x (replace x with the number of the volume right behind the target volume)
  • delete volume
  • select volume n (replace n with the number of the volume that you want to extend)
  • extend size=* (replace * with the amount of space you want to extend in MB, e.g. 500)
