As we know, Windows assigns drive letters to all the drives that are available on the computer, such as internal hard disks, optical drives, SD cards, and external USB drives. Drive letters are alphabetical identifiers for volumes and each drive letter can be used once on one computer.
However, some users discover USB drive letter keeps changing each time they connect it to the same computer. It happens frequently if they use multiple USB drives on one computer. That’s really frustrating! At this time, assigning permanent drive letters to USB drives is needed.
In addition, some users perform regular backup between the USB drive and the computer via a USB hidden copier. With a persistent drive letter, the backup task can be recognized and repeated by the backup utility smoothly. What we need to do is to permanently assign drive letter.
There are three efficient solutions I’d like to recommend to you. Learn how to assign a static drive letter in Windows 10 below:
Solution #1: assign a persistent drive letter with Disk Management

2. Right click the USB drive to which you want to assign a persistent drive letter and select “Change Drive Letter and Paths.”
