You must be logged on as an administrator to perform these steps.

If you don't like the letter Windows has assigned to a new drive or you want to organize your drive letters in a certain way, you can change the drive letter.

You can assign the letters C through Z to each drive on your computer. A and B are usually reserved for floppy disk drives, but if your computer does not have floppy disk drives, you can assign A and B to volumes.

You can see which drive letters are used on your computer by opening Computer.

Open Computer Management by clicking the Start button, clicking Control Panel, clicking System and Maintenance, clicking Administrative Tools, and then double-clicking Computer

Management. If you are prompted for an administrator password or confirmation, type the password or provide confirmation

In the Navigation pane, click Disk Management

Right-click the partition or drive that you want to change, and then click Change Drive Letter and Paths.

Do one of the following

To assign a drive letter if one has not already been assigned, click Add, click the letter that you want to use, and then click OK

To remove a drive letter, click Remove, and then click Yes to confirm that you want to remove it.

hope this helps
