Specifically, Windows typically only offers exFAT formatting for removable drives (like USB flash drives and SD cards). Your external SSD is likely being detected as a fixed disk (similar to an internal hard drive), so Windows hides exFAT from you. This happens even though Windows 11 fully supports exFAT.

Starting with Windows 11, Microsoft added a new way to manage disks that doesn't use the classic Disk Management interface. It lives inside the Settings app, and crucially, it offers exFAT as an option when creating a new volume.

Steps to partition external Hard drive to exFAT on Windows 11:

Step 1: Open Settings

  • Press Win + I to open Windows Settings

Step 2: Navigate to D isks & Volumes

  • Click on System on the left side
  • Click on Storage on the right side
  • Under "Storage management," click Advanced storage settings to expand it
  • Click on Disks & volumes

Step 3: Locate Your External SSD

  • You'll see a list of all your drives
  • Find your external SSD 

Step 4: Delete the Existing NTFS Partition

  • Since your drive came pre- formatted as NTFS, you need to start fresh
  • Click on the NTFS partition to select it
  • Click the Delete button 
  • Confirm the deletion when prompted

Step 5: Create a New Volume with exFAT

  • You'll now see "Unallocated" space on your drive
  • Click the Create volume button

A dialog will appear with these options:

  • Label: Type a name for your drive 
  • Drive Letter: Select an available letter 
  • File system: Click the drop down and select exFAT ← This is where it appears!
  • Size: Leave it as the default
  • Click Format

Step 6: Wait for Completion

  • The process takes about 10-30 seconds
  • Once finished, your drive will be formatted as exFAT and ready for use on both Windows and Mac

 

To partition external hard drive to exFAT on Windows 11. The Windows Settings → System → Storage → Advanced storage settings → Disks & volumes method is your answer. It's built into Windows 11, completely free, uses a graphical interface (no command line), and—most importantly—actually shows exFAT as an option.
