How to fix a USB drive fragmented into separate partitions

Ever plugged in a USB drive only to see several disk drives pop up in the Windows File Explorer. This can’t be fixed by simply reformatting from the File Explorer as you can only reformat each individual drive. In addition, due to the separation of the drive into multiple drives, you lose out on a lot of the storage space. Overall, it’s really inconvenient.

With a little tinkering with Windows’ powerful built-in tools and you can more or less fix that yourself in under 5 minutes.

How to fix a USB drive fragmented into separate partitions

  1. Open Command Prompt or Powershell with Admin Privileges by right-clicking on the desktop Start button or pressing Windows + X.
  2. Once in the command line interface, type in ‘diskpart’
  3. Then type ‘list disk’ to see all disks listed. It should show all your connected hard drives with an associated number. Make a note of your flash drive number, then type ‘select disk [drive number goes here’.
  4. Once you’ve selected that, you can now begin to action on the drive. Enter in ‘clean’, then ‘create partition primary’.
  5. Next, format your drive by entering in the command ‘format fs=fat32 quick’
  6. Type  ‘active’, then ‘assign.’
  7. Once you’re done, type exit to finish your work. Once this is done, your flash drive should be restored to normal.
