How to Increase the Size of My D Drive

By Lysis

After you've installed a hard drive, you can add the extra space to an existing volume using the Windows Disk Management tool. You can also add space to an existing volume if you have some spare space on the hard drive. Using the Disk Management tool, you can add or remove space from a D drive or any other volume configured for use with the Windows operating system. It takes only a few minutes to increase the size on a hard-drive partition.

Things You'll Need

  • Hard drive free space from a new hard drive installation or extra space on an existing drive

Step 1

Click the Windows Start menu button and select "Control Panel." Double-click the "Administrative Tasks" icon and then double-click "Computer Management." This opens a new window with a list of options.

Step 2

Click the "Disk Management" icon on the left of the window. It takes several seconds for Windows to retrieve all your hard drive information. Once it's finished, a list of free disk space and partition volumes are displayed.

Step 3

Right-click the "D" drive and select "Extend Volume." A welcome screen opens. Click the "Next" button on the welcome window.

Step 4

Click the "D" drive on the next window and click "Add." This opens a window prompting you for the amount of free space you want to add to the D drive. The default is the total amount of free space available. Enter the amount in megabytes, or leave the default and press the "Next" button.

Step 5

Click the "Finish" button at the summary window. The D drive now displays with extended free space on it for your use.
