How to Merge Multiple HDD Partitions into One Partition in Windows 10/8/7

After my old Laptop stopped working, I removed its HDD and decided to use it as an external storage drive. But there was a little problem, it had several partitions, and I only wanted one. To solve this issue, I used the following methods.

Or, read below:

Method 1 – Using “Computer Management” Option

You can use this inbuilt Windows tool for the mentioned purpose, but when I tried it for the first time, it was giving me the “The operation is not supported by the object” error. If it happens to you as well, then try the second method.

1. Connect the HDD to your PC or Laptop.

My Computer or This PC

2. Once it is detected by your computer, right-click on “This PC” (Windows 10) or “My Computer” (Windows 7 or 8) icon and click “Manage.”

3. It will open the “Computer Management” screen similar to the image below. Click on the “Disk Management” option under “Storage” drop-down menu.

4. If your HDD has three partitions like mine, then delete two of them by right-clicking and selecting the “Delete Volume” option. Leave the remaining one partition alone.

Note: If you have four partitions, then delete 3 of them and so on.

5. Now, on one side, you will see a large “Unallocated” space, and on the other side, you will see the remaining partition. Right-click on the latter and select “Extend Volume” option.
