How to Customize Drive Letters in Windows 7

How many times have you plugged in your USB thumb drive to discover that it is using a different drive letter than it had before? This usually occurs because the drive letter used before was probably assigned to another USB thumb drive or storage device attached to your computer. This can be frustrating if you create shortcuts to files or folders stored on thumb drives and then can’t access them because the drive letter has changed, rendering the shortcut useless.

Fortunately Windows 7, like its predecessors allows users to assign specific drive letters to any storage device. The how-to below will walk you through the simple process of assigning drive letters to any drive attached to your computer.
