How to Format a USB Drive in Windows

Erase and prepare a removable drive with a selected file system.

Quick Answer

Back up anything needed, right-click the drive in File Explorer, choose Format, select appropriate options, and confirm.

Step by Step

  1. Check power, cables, wireless connection, and any physical switches or indicators first.
  2. Back up anything needed, right-click the drive in File Explorer, choose Format, select appropriate options, and confirm.
  3. Test the device again before making additional changes.
  4. If the problem remains, check Windows Settings and Device Manager, then use the manufacturer's official support information for the exact model.

If That Doesn't Work

  • Change one thing at a time so you know which action fixed or caused the problem.
  • Avoid downloading drivers or device utilities from unofficial driver-download websites.
