How to Partition a Hard Drive in Windows 7

Partitioning a hard drive involves splitting it into several logical units. While many users rarely partition their drives, this process comes with several benefits. The primary advantage is that partitioning separates the operating system from your data, thereby reducing the risk of data corruption.

Open the Computer Management tool. Click the Start menu, type 'Computer Management' in the search bar, and press enter.

Select the Disk Management tool. Click on Disk Management on the left side of the window to view all your drives and their partitions on the computer.

• In the example image, there is one drive with two partitions.

Create space for a new partition. Right-click the partition you want to resize and select the Shrink Volume option.

• In the example image, the selected drive is (C:).
• Note: There may be a partition labeled System Reserved. We recommend not modifying this partition.

Shrink the drive. Enter the amount of space you want to shrink the drive by in megabytes (1000 MB = 1 GB). Then, click the Shrink button.

• In this example, the drive is shrunk to 10000 MB, or 10 GB.
• Note: You cannot shrink the volume beyond the amount available in the Size of available shrink space in MB field.

Create a new drive. You will now see an unallocated partition in the Disk Management window. Right-click the unallocated partition and select New Simple Volume to create a new partition.

The New Simple Volume Wizard will begin. The New Simple Volume Wizard dialog box will appear. Click the Next button to continue.

Enter the size of the new partition. Input the amount of space you want to allocate for the new partition and click Next.

• In the illustration, the maximum available space has been allocated to the new partition.
• Note: You cannot create a partition larger than the available memory space.

Assign a name to the new partition using a letter or a path. Choose a letter from the menu to label the new partition and then click the “Next” button.

• In the example, the letter (A:) is selected.
• The letter or path you choose will be used by Windows to identify and navigate to your new partition.

Configure settings for the new partition.

• Click on Format this volume with the following settings: (Format this volume with the settings below):
• For File System, select NTFS.
• For Allocation unit size, choose Default.
• For Volume Label, input a name for your new drive.
• Click on Perform a quick format (Perform quick formatting).
• Then, click the Next button.

Create the new partition. Review your settings and then click Finish to complete the process.

Format the new partition.

• A dialog box will appear requesting you to format the new disk partition. Click on Format disk (Format the disk).
• Another window will pop up. Keep the default settings and click the Start button.
• A warning will appear. Click OK.

Check the new disk. If the steps were followed correctly, your new disk will be visible in the Disk Management window.

• Before proceeding, we strongly recommend that you back up all your data to another computer or an external storage device. This will help prevent data loss in case of any errors.
