Have you ever run into the issue of plugging in a USB flash drive to your computer and it doesn’t work  or doesn’t show up because there is already another drive using the same drive letter that the USB drive wants to use? Whether you have mapped a network drive or your computer has an internal or another external drive using the same drive letter…this can be frustrating. Updating the drive letter isn’t that difficult, but I find myself forgetting the steps since it doesn’t happen very often. These steps are also a little different from how drive letters were changed on previous versions of Windows, such as Windows XP.

In this tutorial, I will go through the steps to change the drive letter of my USB Pen drive. It is called a Pen drive, because it dual purposes as a pen or a laser pointer, but it is just a basic removable storage device.

If you need to update a drive letter using Windows 7 perform the following steps:

1. Go to Start > Computer -> Manage (right click).

2. In the Computer Management dialog window double click on Disk Management.

3. Right click on the disk in which you want to change the drive letter for and click on Change Drive Letter and Paths…

I am changing the drive letter of my removable USB drive which is currently assigned the letter “F”. Note:  I right clicked in the top pane, but you could also right click on your USB drive in the bottom (graphic view) pane as well

4. Make sure to select the current drive letter in the Change Drive Letter and Paths for… dialog window and click on the Change… button

5. Use the dropdown box in the Change Drive Letter or Path dialog window to select another drive letter. I choose letter G. Click the OK button.

6. Close the Computer Management window and you are done!

This is what the final result will look like:
