Change Drive Letters in Windows Vista

After a new hard drive installation or maybe just to keep things organized the way you like, you may want to change the drive letter of a hard drive partition or a CD/DVD/BD drive in Windows Vista. The Windows Vista Disk Management tool makes this easy.

Note: You cannot modify the drive letter of your main partition on your PC. In a normal Windows Vista installation, this is the "C Drive".

Follow these steps to change a drive letter in Windows Vista:

Note: Not using Windows Vista? See the tip at the bottom of the page for help.

Difficulty: Easy
Time Required: Changing drive letters in Windows Vista usually takes less than 5 minutes

Here's How:

  1. Open Windows Vista Disk Management from the Computer Management utility.

    Note: You can also open Disk Management from the Command Prompt in Windows Vista but starting it via Computer Management is more common.

  2. On the right-hand side of the screen, locate and right-click on the drive that you wish to change the drive letter of and choose Change Drive Letter and Paths....

  3. In the Change Drive Letter and Paths window, click on the Change... button.

  4. The Change Drive Letter or Path dialog box will appear. Choose the drive letter you wish to assign to this partition.

    Click OK.

  5. The Confirm window that appears advises you that "Some programs that rely on drive letters might not run correctly. Do you want to continue?".

    Note: If you have software installed to this drive, the software may stop functioning after a drive letter change. Nearly all software defaults to the primary drive though, so this is rarely a concern.

  6. If you're sure you want to make this change, click Yes. Depending on the speed of your PC, the change should be nearly instant.
