How to Create Partition on Hard Drive without Formatting in Windows 7/8/10?

The Scenario

I am an office assistant. Every day I have so many data and files to keep, but I find the volumes in my computer cannot meet my needs because it takes much time to find a specific file or folder. In this case, I want to create several new volumes to help me. Unfortunately, I am a green hand in computer and I don't know how to rebuild the new one. Having asked help from others and operated by myself, I find two efficient ways to create partition on hard drive. Let me show them one by one.

Note: Before all the operations, please ensure there is unallocated space and it must be separately displayed on the hard drive. If not, please try to generate the unallocated space by free partition manager

How to create partition with disk management in Windows 7/8/10?

To begin with, please try to understand following conceptions since you may need them during the operations

The Partition Type

Primary partition: It is usually used to save the files and programs of operating systems. Meanwhile, it is the guidance for system booting.

Extended partition: It is a member of MBR and made up of many logical drives.

Logical partition: It is the portion of extended drive. Once an extended drive has been created, you can set up it as many as possible.

The Partition Size

The minimum and maximum size that you can use to create a partition will be given to you after query in Disk Management. You can decide the size of the created partition.

The Drive Letter

Unused letter is available for you to choose. Generally speaking, the system will default it for new drive. Yet, if you choose "Do Not Assign a Drive Letter or Drive Path" option, it's up to you to assign the new drive's letter afterwards.

Format Partition

It is necessary to format drive beforehand in order to save data and files. The system will provide you detailed format information. FAT32 and NTFS are two types of file system. Compared with each other, FAT32 is simple and readable on many OS. As for NTFS, it has better security features, better recovery capabilities and file-level compression built in.

Create New Simple Volume in Disk Management

After a brief acknowledgement of above terms, let’s learn how to create new partition using Disk Management

Step 1: Right click "My Computer" and choose "Manage". Then, you will enter the computer management interface. Please choose the "Disk Management" on the left options to make sure if the unallocated space is existed in the disk.

Step 2: Right click the unallocated space and select "New Simple Volume". Following, select "Next". There are three options: Primary, Extended or Logical Partition. Actually, the system will default the type of new volume. If the unallocated space is located in the primary drive's area, the new one will be primary one, while in extended drive area, it will be logical one.

Step 3: Please following the wizard, finish the size, file system, drive letter step by step. After that, choose "Finish".

Create partition on hard drive without losing data

Disk Management is helpful and you can easily create a new volume. However, all operations are based on the unallocated space. If you don’t have unallocated space on the hard drive or you want to create a new partition from one existing partition directly, try this free software to create partition on hard drive. AOMEI Partition Assistant Standard allows you to create both NTFS and FAT32 partition from the existing one without formatting and losing data. You can also use it to create partition on external hard drive, USB drive, removable drive, or portable hard drive. It is Windows 10/8/7/XP/Vista supported. Firstly, please free download Partition Assistant Standard Edition and launch it.

Step 1: Right-click the redundant partition D and choose "Create Partition". In the coming up window, you can edit the specific information. Also, you can click "Advanced" to edit more. Specify the size and location by dragging and moving or by selecting the options. Then, select "OK".

Step 2: Do remember to click "Apply" to execute the operations.

Each method is workable. Compared with each other, the latter can support creating any FAT32 drive more than 2TB, while the former only support 32GB at most.

To sum up, the latter free software is superior to the former one. It provides the advanced features, like resize (extend/shrink/split) partition, allocate free space, etc. Moreover, you can use this software to create Windows to go USB drive if you’re running Windows 8 or Windows 10 (No need to being Enterprise edition). Thus, installing Windows 10 on external hard drive is also possible.
