"You cannot format this volume", Can I?

The "You cannot format this volume" error is a common error that can occur when trying to format a drive that contains the Windows operating system. This error can happen for several reasons, but the most common cause is that the Windows system files are stored on the drive. When you format the drive, you are essentially trying to erase these system files, which is not allowed.

Another possible reason for this error is that the drive is set to read-only mode, which prevents it from being formatted. In either case, you will need to use a different tool to format the drive if you want to remove the Windows operating system from it.

Fortunately, this error sounds challenging. You can overcome it with a user-friendly format tool - EaseUS Partition Master.

While it is possible to reformat an SSD with an OS on it, it is generally not recommended as it can lead to data loss.

If you reformat the OS-installed SSD from File Explorer, you will see the error message "You cannot format this volume". Because the drive contains Windows operating system, it will cause a "fail to boot" error.

To reformat an SSD with an OS on it, you need another third-party software to create a bootable USB. Then start the formatting process.
