Some people report that their USB drives are always mounted offline when they are inserted into the Windows PC.

The USB drive doesn’t show in File Explorer. Open Disk Management. They find that the USB drive is shown as Online but has no drive letter.

When they attempt to format the USB drive in Disk Management, the system says “Windows cannot format the volume because the volume is offline. Please try to online the volume by assigning a drive letter or path to the volume first.”

However, even if they assign a drive letter to the USB drive to make it shown in File Explorer, it is still not accessible.
