This tutorial explains how to change drive letter from Command Line. You can assign any letter (which is not already associated with a hard drive) to a particular hard drive. All you have to do is use a free tool, called “Remount” and execute a very simple command. Changing a drive letter will take only a few seconds. You can also set the previous drive letter anytime.

Apart from changing a drive letter, you can also swap drive letters. For example, you can change Drive Letter E with drive letter F and vice-versa. So this command line tool is a good option to try. Unlike other command line tools, using this tool is very easy.

drive letter changed from E to Z

In above screenshot, you see drive letter changed from E to Z. I did it using this command line tool.

Note: This tool can also change the drive letter for system drive (usually it is C drive), but I will suggest you avoid this option. I tried it and it corrupted my system. I guess I have to re-install Windows. Therefore, my suggestion is to use this tool only for other drives.

How to Change Any Drive Letter from Command Line?

Step 1: Grab the zip file of this tool and then extract it. You will see two folders: Win32 and x64. Depending on your PC version, you can open Win32 (if your PC is 32-bit version) or x64 folder (if your PC is 64 bit). After that, you will find ReMount.exe application file. You can execute this application file to view the supported commands.¬†However, to actually change the drive letters, you will need to run this application from command prompt. Let’s see how to do that.

Step 2: Type cmd on Search box or Run Box (Win+R) to open Command Prompt window. When Command Prompt window opens, drag n drop ReMount.exe file on that window.

The command is not completed yet.

Step 3: Continue the command by pressing the space key. After that, to change the drive letter of a hard drive, your command would be: “X: Y:“. Here, X is used to represent current drive letter and Y is the new letter. So your complete command would be: ReMount.exe X: Y:

execute drive letter change command

Execute the command and it will start the processing. Within a second or two, it will change the drive letter with new letter.

You can execute the similar command (ReMount.exe Y: X:) to get back the previous drive letter.

Step 4: This is an optional step, but very useful when you want to swap drive letters. Suppose you want to replace drive X letter with drive Y letter, then your command would be: ReMount.exe X: Y: -s

execute swap command

The parameter “-s” is used for swap command. Execute the command and drive letters will be swapped.
