How To Partition A Hard Disk In Windows 10?

Summary: If there is only a single SSD on your desktop or laptop, usually only the C disk exists in the system, but what if you want to have the D disk to store files? Don’t worry, you can use the built-in Disk Management of Windows to partition the hard disk. This article will teach you how to partition a hard disk so that you can freely allocate the space you want!

Why Need Partition Hard Drive?

Partitioning allows you to allocate one portion of your drive to Windows itself, with another for all your music, videos, and other files, so they don’t get deleted when you reinstall your operating system. But it can also cause as many problems as it solves: if you run out of space on one partition and have too much free space on the other.

Why do we need to partition a hard drive? Here are the common reasons to partition a new/existing hard drive:

  • To make full use of hard drive space, splitting it into several partitions.
  • Operating System update.
  • The changes in computer and hard drive usage.
  • The change of computer users needs.

So if you have only C disk in your computer and come across the above situations, please follow the method below to partition the hard drive.

  8. You’ll then enter the New Simple Volume Wizard to choose the volume size, drive letter, and file system. If you’ll only be using Windows, you can choose NTFS as the format. You might want to choose exFAT if you plan to share data between other operating systems. partition hard disk 3


Partitioning a hard disk is purely to facilitate the storage of data or to classify the data. The new disk is divided from the same SSD and if there is a problem with the SSD, the whole army will be wiped out! The best way is to expand another SSD or an external storage device. And the most important thing is to develop a good habit of backup to avoid data loss!
