Why Do You Need to Unpartition a Hard Drive?

If you want to add unallocated space to another hard drive for extending, you may need to unpartition a hard drive, which means deleting partitions or partitions on a hard drive. Unpartitioning merges the partition back into the original drive and it will add space back to the original drive which had been partitioned.

In addition, OEM computers can come with unnecessary partitions that take up space. You can also unpartition them.

Note: If you are planning to sell or recycle your computer, you should not only unpartition the hard drive, but also wipe the hard drive. In addition, a partition on a hard drive can only be deleted and wiped when it is not currently in use.

How to Unpartition a Hard Drive via Disk Management

Disk Management is a piece of built-in disk management software. You can manage your disks in it.

Tip: Before you delete partitions on a hard drive, please back up data in advance.

Step 1: Press “Windows + R” keys simultaneously to open the Run dialog box. Then, type “diskmgmt.msc” in the search field and press Enter to open Disk Management.

Step 2: In the Disk Management window, you will see a list of disks. Right-click the partition you want to delete and click Delete Volume. Then, the partition and all the data on it will be deleted.

  • Type "cmd" in the Run box and press Enter key to open Command Prompt.
  • Type command "diskpart" in cmd.exe input window and press Enter key to open diskpart.exe input window.

  • List partition
  • Select partition * ("*" stands for the partition you want to delete.)
