You’ve connected a USB flash drive, heard the familiar Windows sound of connection, yet no drive letter shows up. You then go into Disk Management for Windows and see the device and memory, but the USB flash drive doesn’t get assigned a drive letter.

What should you do?

Most of the time, Windows will automatically assign a drive letter to any connected storage device—whether it’s a USB stick, USB hard drive, or other mass storage device.

However, if a drive letter isn’t assigned, there’s a quick fix to get your computer working properly again:

1. Open Command Prompt as Administrator (search for CMD, then right-click and select “Run as Administrator”).
2. Type diskpart and press Enter.
3. Once in DISKPART, type automount enable and press Enter.

If the above steps don’t solve the problem, there could be conflicting registry entries from past USB devices that disabled or interfered with the automount function.
