6 Ways to Change the Drive Letter in Windows

Change Drive Letters Windows Featured

If your PC suddenly stops showing one of your internal drives in the file explorer or not list your external drive, it could be due to the OS getting confused with the drive letters. Simply changing your assigned drive letters can help you bypass this conflict. Here are six ways to change the drive letter.

Is It Safe to Change a Drive Letter in Windows?

Changing the drive letter is not entirely harmless and can cause significant problems based on the contents of your drive. If you have applications and software installed on your drive, those applications may cease to work.

For example, if you change the name of your D: drive to an F: drive, then the software installed in the D drive will still search for code in the D: file. While you can still access the data inside, there may be errors that will cause a nuisance in your day-to-day usage.

However, you may safely change the letter of some drives. If a partition simply includes data files that you rarely use, changing the drive letter may cause minor inconvenience, but nothing serious. The letters of external drives can almost always be changed without any problems.

Frequently Asked Questions

1. How are drive letters assigned in Windows?

Drive letters are assigned to every new drive in alphabetical order. Traditionally, the A: and B: drives were used for floppy disks, and the system drive on which Windows is installed is named C: by default.

2. Can I change the drive letter for the System Drive?

No, changing the drive letter on the system drive is not possible, as Windows is installed on the system drive. If that was changed, the system drive would not be found and the computer would cease working.

3. Can I switch drive letters among two drives?
