How to Change or Assign a Drive Letter in Windows

Give a detected disk or partition a letter so it can appear in File Explorer.

Quick Answer

Open Disk Management, right-click the volume, and use Change Drive Letter and Paths.

Step by Step

  1. Check power, cables, wireless connection, and any physical switches or indicators first.
  2. Open Disk Management, right-click the volume, and use Change Drive Letter and Paths.
  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.
