Do USB Drives Have Partitions

Yes. In fact, you don't need to partition a new USB drive if you just use it to store and move files. However, you may need to partition your USB drive when you need to:

  • Create bootable USB drives
  • Encrypt a part of your USB flash drive
  • Change the file system types of USB flash drives
  • Organize the storage volume of a USB flash drive

You may partition your USB drive based on the reason above. However, what should you do if you don't need many partitions anymore? The answer is to merge partitions. 

You can merge partitions on USB drives to get more free usable storage and efficient management of your partitions since too many partitions on your USB may make it difficult to find a specific file.

Way 2. Merge Partitions on USB Drive with Disk Management [With Data Loss]

What is Disk Management? It is a Windows built-in disk utility. It also allows you to merge partitions on a USB, but there is something you need to know in advance.

Notice:

1. Disk Management can only work on your USB if your operating system is after Windows 10 1803. 

2. If you have two or more partitions, you will need to delete all partitions one by one and create a new one.

Now, follow these steps to merge partitions on a USB drive with Disk Management.

Step 1. Search "Create and format hard disk partitions" to launch Disk Management. 

Step 2. Right-click the partition that you want to merge with the other partition and select the "Delete Volume" option.

Step 3. Confirm your deletion, and then right-click on the partition you want to merge. Choose the "Extend Volume."

Step 4. You can finish merging the targeted partitions following the "Extend Volume Wizard."

Sometimes, you may see that the Extend Volume grayed out. This is because your version is older than Windows 10 1803, or the USB doesn't have enough unallocated space. Under this circumstance, you can choose EaseUS Partition Master.

Or, if you are a computing professional, you can use Diskpart commands to merge partitions on a USB drive.

Way 3. Merge Partitions on USB Drive with Diskpart [With Data Loss]

Diskpart is also a good way to manage your disk partition with commands. However, you need to be extremely careful when you type the commands. If you type a worry letter or number, you will easily suffer data loss.

Now, follow these steps to try Diskpart commands.

Step 1. Click the search icon and type: Command Prompt

Step 2. Then hit the "Enter" key each time you type a command below:

  • diskpart
  • list disk
  • select disk 1
  • list partition
  • select partition 1
  • delete partition

Please replace "1" with the correct number, or you may suffer data loss. Be careful when you type the commands.

Step 3. Finally, type the command to merge the partition with the unallocated space: extend

Sometimes, you may receive error messages like Diskpart failed to extend the volume. You can try to convert FAT32 to NTFS to help with this issue or use EaseUS Partition Master to avoid this error.
