How to Use DiskPart to Merge Partitions

Please provide the English content you want translated, and I'll do my best to translate it into Chinese.

Each hard drive needs its integral parts to ensure it can store information categorically. There's no need to combine information into various sections of the hard drive, as this makes tracking easier and more convenient. Different system drives typically run scheduled maintenance tasks like cleaning or defragmentation to provide a better computing experience to users.

Yes, you can use the Diskpart command in Command Prompt to merge partitions. Here's a brief guide: 1. Open Command Prompt as an administrator. To do this, right-click the Start button, and select "Command Prompt (Admin)". 2. Type `diskpart` and press Enter. This will launch the Diskpart utility. 3. Type `list disk` and press Enter. This will show a list of all disks on your system. 4. Identify the disk that contains the partitions you want to merge. Note the disk number. 5. Type `select disk [number]`, replacing `[number]` with the disk number you noted, and press Enter. This selects the disk for further operations. 6. Type `list partition` and press Enter. This will display the partitions on the selected disk. 7. Identify the partitions you want to merge. Make sure they are next to each other (i.e., Partition 1 and Partition 2, or Partition 2 and Partition 3, etc.). Note their numbers. 8. Assuming you want to merge Partition 2 into Partition 1, type `select partition 1` and press Enter. 9. Then, type `extend [size=]`, but don't press Enter yet. If you want to merge all available space from Partition 2, just press Enter now. If you want to specify a size, type the size in MB (e.g., `extend size=5000`) and then press Enter. Please note that Diskpart doesn't directly support merging non-contiguous partitions or merging partitions from different disks. Also, be cautious when using Diskpart, as any mistake can lead to data loss. Backup your important data before proceeding.

Diskpart is a command-line application in Windows 10 that enables you to manage disk partitions using the Diskpart command prompt, including creating, merging, extending, shrinking, formatting, deleting, and erasing disk partitions. DiskPart can be executed without booting into the Windows system and directly controls volumes and partitions on hard drives, including hidden recovery partitions. This makes it a powerful tool, but one that should be used with caution, as any formatting operations performed on a hard drive are irreversible once executed. The robust capabilities of DiskPart also make it a useful solution for issues like data corruption on USB flash drives or problems with SD cards that cannot be resolved through simple formatting.

Before you can use a “diskpart” command, you must first list the objects and then select one to focus on. Once an object is selected, any disk-partitioning commands you enter will be applied to it.

How to Merge Partitions Using Diskpart CMD in UTF-8 Encoding Diskpart is a command-line tool built into the Windows operating system for managing and manipulating disk partitions. Here's how to merge partitions using Diskpart CMD: 1. Open Command Prompt (run as an administrator): - Press `Win + X` and then choose "Command Prompt (Admin)". 2. Enter the following commands one by one (press Enter after each): ``` diskpart ``` This will launch the Diskpart utility. 3. Input the following command to list all disk information: ``` list disk ``` Identify the disk number you want to work with, typically 0, 1, 2, etc. 4. Select the disk you wish to operate on: ``` select disk <disk_number> ``` Replace `<disk_number>` with the actual disk number. 5. List all partitions on that disk: ``` list partition ``` Note the numbers of the two partitions you want to merge. 6. Choose the first partition to merge: ``` select partition <partition_number1> ``` Replace `<partition_number1>` with the first partition's actual number. 7. Delete the first partition to free up space: ``` delete partition override ``` 8. Select the second partition to merge: ``` select partition <partition_number2> ``` Replace `<partition_number2>` with the second partition's actual number. 9. Extend the second partition to occupy all available space: ``` extend ``` This will make the second partition take up the space previously occupied by the first partition, effectively merging them. 10. Exit Diskpart when finished: ``` exit ``` Please note that these operations permanently delete data from the selected partitions, so ensure you back up important files beforehand. Also, double-check that you've selected the correct partitions to merge to avoid data loss.

Administrators use Diskpart to create, delete, and resize partitions on hard drives, and to assign or reassign drive letters to newly inserted disks. In a RAID array, Diskpart is useful for partitioning newly installed disks for maximum I/O efficiency. For many server applications – Microsoft Exchange Server, for example – documentation actually recommends that you use Diskpart to create primary or extended partitions. Diskpart also allows you to re-strip existing data, which can be handy when installing a RAID array.

Step 1: Open the Start menu and type "diskpart.exe."

Step 2: When the Command Prompt window appears, type 'list volume'.

Step 3. Type in the 'select volume' command, for example, if you're merging E:, type 'select e'.

Step 4: Type “delete volume” to free up space on the drive for use by other partitions.

5. In the “Disk Management” prompt, type “extend” to merge the partition with the unallocated space.

## Use a Disk Partitioning Software to Merge Partitions

Partition Master is a professional disk management tool that lets you create, resize, merge, clone, and format partitions. It essentially helps you manage Windows partitions without losing any data. It can also build, format, and erase USB drives, SSD drives, HDD drives, and SD cards. While there is a paid version available, the free version pretty much covers all your partitioning needs.

Advantages:

• User-friendly even for those not proficient with computers
• Allows previewing the effects of changes before applying them
• Includes a multitude of useful actions

Here's a step-by-step tutorial on how to merge partitions using Partition Master: 1. **Download and Install Partition Master**: First, visit the official website of Partition Master (like tools or MiniTool) and choose the appropriate version for your operating system (Windows or Mac). Download and install the software. 2. **Launch Partition Master**: After installation, open the Partition Master application. The main interface will display all hard drives and partitions on your computer. 3. **Select the Partitions to Merge**: Locate the two adjacent partitions you want to merge. Keep in mind they must be next to each other for direct merging. For instance, if C drive and D drive are adjacent, you can merge them. 4. **Right-click the Source Partition**: Right-click on the partition from which you want to move space (usually the smaller one) and select "Merge Partition" from the drop-down menu. 5. **Choose the Target Partition**: In the pop-up window, select the target partition you want to merge into. This is typically the larger partition. 6. **Confirm the Action**: Once you've made the correct selection, click "OK" or "Next". The program will show a preview of the merged partition layout. 7. **Execute the Operation**: Click "Execute Operation" or a similar button on the main interface, then confirm your choice by clicking "Apply" or "OK" in the prompt. Note that this process may take some time, especially when dealing with large amounts of data. 8. **Wait for Completion**: Partition Master will start the merging process. Do not close the program or turn off your power during this time to avoid data loss. 9. **Verify the Result**: Once the merge is complete, restart your computer, and check the new partition layout in "My Computer" or "File Explorer". You should now see that the original two partitions have combined into one larger partition. Make sure to back up important data before attempting such operations as a precaution. While tools like Partition Master are generally reliable, there's always a risk involved with disk operations.

Step 1: Select the target partition

Right-click on the partition you want to add space from and select “Merge”.

Run the disk partition manager software.

Merge adjacent partitions to be combined

Merge with the partition adjacent to the previously selected one.

Click "OK" to proceed.

Step 3: Perform the operation: Merge partitions

1. Click the "Perform Tasks" button at the top, then click "Apply."
2. The program will merge the drives, and the files from the second partition will be added to the first one.

Merge Two Disk Partitions Using CMD

If users plan to merge partitions on two disks into one, they should use tools like Partition Master because the Diskpart command cannot merge partitions on two dynamic disks.

You can use the Partition Assistant tool to merge adjacent partitions to increase the size of a partition.

Step 1: Transform the basic version into a dynamic one

Click “Disk Converter,” and then select “Convert Basic to Dynamic.” Click “Convert” to proceed.

2. Confirm that the disk is converted from Basic to Dynamic.

4. Select another disk (which must have at least 1 MB of free space at the end) and convert it to a dynamic disk in the same way.

After both disks have been converted to Dynamic Disks (as shown below), you can now proceed with Step 2 to merge the free space from one disk to the other.

Step 2: Merge Two Disks into One Disk

Note: The other dynamic disk must have unallocated space. If not, delete all partitions on it with Partition Master. Besides, you can't merge the system partition even if you have converted it to a dynamic disk.

4. Right-click on the entire disk and select “Resize/Move.”

Select the disk and adjust its size

Resize the partition by dragging the panel with your mouse to the left or right.

Sometimes, the unallocated space might be to the left of the partition that you want to extend. If so, move the left partition handle to the left to the desired size.

Click Run 1 Task and then Apply.

Which method is right for me?

I will opt for the Partition Master Free tool, as it optimizes low disk space by managing partitions, thus boosting my computer's performance. Although I can edit basic disks and partitions, advanced applications also allow me to modify dynamic volumes. The Partition Master software is compatible with Windows 10/8/7/Vista/XP, assisting me in resizing, moving, merging, and copying partitions.

For beginners and experts alike, Partition Master is more reliable than Diskpart. Here are some important features of the tool:

• OS Migration to SSD/HDD
• Cleaning and Optimization
• Data Erasure
• Resizing or Moving Partitions
• Clone Partition
• Explore Partition
• Format Partition
• Delete Partition
• Merge Partitions
• Hide Partition
• Change Drive Letter and Label
• Convert Drive to Logical Drive

Disk partition manager also removes the risk and difficulty of hard drive partition resizing. Anyone – or I – can use it with just a few clicks, without special training.

Conclusions

Well, people might be able to merge partitions via CMD, but Diskpart cannot merge two partitions on two different disks. If one likes to do so or needs a simpler and more powerful partition tool, they can try using the Partition Master tool. Partition Master has a user-friendly program with an easy-to-understand interface, and one can use it without any issues.
