Resolve exFAT disk not appearing on Windows 11/10
If the exFAT disk is not appearing on your computer, follow the solutions mentioned below to resolve the problem.
- Connect to a different port

Let’s discuss each solution in detail.
1] Connect to a different port

- Press Win + S, type “Disk Management” and click Open.
- Locate the exFAT disk, right-click on it, and select Mark Partition as Active.
- Follow the on-screen instructions to mark the disk as active.
