How to Use DiskPart to Merge Partitions

Updated by Tracy King on Jul 30, 2021

Each hard drive needs to have fundamental parts which guarantee that it can oblige information according to the classification. It's anything but an absolute necessity to merge information into more than one part of a hard drive and looks reasonable to clients since this route following of information gets simpler and much advantageous. Various framework drives frequently run planned support undertakings like cleaning or defragmenting, to invest a superior computing experience to the clients.

Can I Merge Partitions with Diskpart CMD

Diskpart is a command-line application in Windows 10 that allows you to manage disc partitions by using the Diskpart command prompt, including the ability to create, merge, extend, shrink, format, remove, and erase disc partitions, among other things. DiskPart can be executed without the commencement of the Windows system and explicitly controls volumes and partitions on a hard disc, including partitions for hidden recovery. This makes it a strong weapon and not one without certain care; because no formatting can be undone on a hard disc once the action is taken. DiskPart's power also implies that it is a good way to remedy problems, such as USB flash drive data corruption and SD cards, which cannot be fixed in Windows by simple formatting.

You must first list, then choose an object to concentrate, before you can use diskpart instructions. Any disc component instructions you type will work on this object when an object has focused.

How to Merge Partitions with Diskpart CMD

Administrators can scan with Diskpart to build, remove and re-size hard drive partitions and assign or reassign drive letters to newly inserted discs Disk part is useful in partitioning your drive to increase the I/O efficiency of freshly installed hard drives in a RAID array.

Merge Partitions from Two Disks with CMD Alternative

If people tend to merge partitions on two disks as one, then they should use EaseUS Partition Master as the Diskpart command cannot work to merge partitions on two RAD disks which are dynamic.

One should use the EaseUS Partition Master and select the adjacent partitions to combine them into a larger one and expand their size. 

Step 1. Convert Basic into Dynamic

  • Right-click one of the disks (disk 0, disk 1 or disk 2) that you want to merge, choose "Convert to Dynamic".
choose the first disk and convert to dynamic
  • Confirm the disk conversion from the Basic to Dynamic.
merge disk 0 and disk - 2
  • Select the other disk (with lots of free space) and convert it to a dynamic disk in the same way.
convert the second disk into dynamic
  • When both of the disks have been converted into dynamic disks, as shown below, you can follow Step 2 to merge free space from one disk to another now.

Step 2. Merge Two Disks into One Disk

Note: The other dynamic must be unallocated space. If it's not, use EaseUS Partition Master to delete all the partitions on it. What's more, you cannot merge a system partition even you have converted to dynamic.

  • Select the full disk, right-click on it and choose "Resize/Move".
choose the disk and resize
  • Use your mouse to drag the partition panel rightward or leftward to extend partition size.

Sometimes, the unallocated space is on the left of the partition you want to extend. If you want to move unallocated space, just drag the left partition handle leftwards to the size you want.

resize the disk
  • Click "Execute Operation" and you are able to merge space from one disk to the other.

Which Method Is Right for Me

I will opt for EaseUS Partition Master Free because it will let me optimize low disk space by managing partitions to improve my PC's performance. While I can edit basic disks and partitions, the premium app will also let me change dynamic volumes. EaseUS Partition Master Software is for Windows 10/8/7/Vista/XP that will help me resize, move, merge, and copy partitions. 

EaseUS Partition Master is more reliable than diskpart for beginners as well as for experts; the following are the important features of EaseUS Partition Master

  • Migrate OS to SSD/HDD
  • Cleanup and Optimization
  • Wipe data
  • Resize or Move disk partitions
  • Clone partition
  • Explore partition
  • Format partition
  • Delete partition
  • Merge partition
  • Hide partition
  • Change drive letter and label
  • Convert drive to logical

EaseUS partition manager also takes the risk and difficulty out of resizing partitions on hard disks. Anyone or I can use it without any special training with just a few clicks.

Conclusion

I think people can merge partitions using CMD but diskpart cannot work to merge two partitions on two disks. If people prefer to do so or need an even easier and powerful partition tool, they should try to use EaseUS Partition Master. EaseUS Partition Master is easy-to-understand user-friendly programming and accompanies to utilize it without any problem.

  • It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives. You can move partitions around, resize them, defragment, and more, along with the other tools you'd expect from a cloning tool.
