Almost everyone has a USB drive (also called pen drive, thumb drive, and flash drive) these thanks to the falling USB storage price. Each time when you insert a USB drive Windows might give a different drive letter if you are using more than one drive at once. Although this is not a big deal for most users, you might get confused if you often connect the multiple USBs of the same size and brand.
To avoid this confusion, I have a great tweak which lets you assign a unique drive letter to all the USB drives. Here is what you need to do:
Make your USB drive always use the same drive letter
Warning: Move the contents of the drive before changing the drive letter as some application might not run properly. We advise you to move the data to a local drive before changing the drive letter. You may move back the data to the USB drive once the drive letter is changed/assigned.
1. Insert your USB drive into the USB port.
2.Type diskmgmt.msc in the Start Menu Search box or in the Run dialog box and hit the Enter key.
3. In the Disk Management window, right-click on your USB drive and select Change Drive Letter and Paths option.
5. Choose a drive letter for your lovely drive.
