How to Partition A Hard Drive in Windows 10

What's Disk Partition in Windows 10?

Windows users, who purchased a new Windows 10 computer/laptop or installed a new HDD/SSD in the Windows 10 computer, should be very familiar with the number of local disks under This PC in Windows Explorer. Usually, there is only one partition labeled as Local Disk (C:) on a hard drive which is made by the computer manufacturer. However, we know very clearly that it's far from enough to have only one partition for running operating system, installing programs or saving personal data. The truth is, every user can divide one hard drive into two, three or even more. As for most people, they want to partition a hard drive in two scenarios.

One, to manage computer data in a clean and logic way. With one more partition on a hard drive, they can separate Windows OS, downloads, games, or personal documents/pictures/videos related to work or school in different drives with customized labels.

Two, for data safety. If the entire hard disk contains all your system files, personal data, and programs, it's much riskier than placing OS and non-OS files in different locations. Even you have to reinstall OS due to a sudden crash or computer death, the data on other drives like D, E, F, G won't be affected.

Thus, as long as you have such demand to create a number of partitions, this post is for you. Before proceeding with the details, there are two useful tips for a successful Windows 10 disk partition.
