When you want to format a PS4 external hard drive on a PC, you first need to make sure that your computer is up to date with the latest security patches. Then, you need to create a new partition on your hard drive and name it “PS4”. Finally, you need to create a file called “Format.txt” and place it in the root of your PS4 external hard drive. Here’s how:

  1. Open Windows Explorer and navigate to the root of your hard drive.
  2. Right-click on the “PS4” partition and select “Create Partition”.
  3. Type “Format.” into the text field and click on the OK button.
  4. Navigate to the location where you placed “Format.txt” and click on it.
  5. Click on the OK button again and confirm your changes by clicking on the OK button again in Windows Explorer’s confirmation dialog box.
