If you use multiple USB drives, you’ve probably noticed that the letter with which each is named in the operating system changes each time you connect one. This is something that Windows does by default: because it is about removable storage, the system does not allocate one persistently.
Unless, of course, you tell him otherwise. With a very simple process you can assign a persistent letter to a USB drive, an SD card or external optical drives. This way you can use them more quietly as backup units, or to use portable applications that prefer that the unit always have the same letter.
To change the drive letter, first we will have to open the Start Menu and type “Create and format hard disk partitions” . This will open the Disk Management utility. The procedure, by the way, works the same way in all modern versions of Windows.
The next thing is to go to the USB drive that we want to modify and right click on it. In the menu that will appear, we select the option Change the drive letter and paths . This window will open:
We will see the letter currently assigned. To change it click on Change
In the window that appears, make sure that the Assign the following drive letter option is selected. Then use the drop-down menu to select a new one. When finished, tap OK.
As a recommendation, we suggest you choose a letter between M and Z. Basically because the previous ones may already be assigned to units that do not have to appear in the file browser (e.g. optical drives or card readers). These letters we propose are almost never used on most Windows systems.
Windows will then display a warning message, saying that some applications may rely on drive letters to work. In most cases you should not worry . Go ahead and in the next window you will see that the change has occurred.
From now on, every time you disconnect and reconnect the drive, the letter will be persistent and will not change.
