If your Ps4 external hard drive is not formatting correctly, there are a few things you can do to try and fix the problem. Here are a few tips on how to reformat a Ps4 external hard drive:

  1. Make sure that the external hard drive is properly connected to your PS4. If it isn’t, the PS4 may not be able to recognize it.
  2. Try formatting the external hard drive using the PS4’s built-in format tool. This will erase all of its data, so make sure you have everything you need before proceeding.
  3. If formatting the external hard drive using the PS4’s built-in format tool doesn’t work, try using a third-party format tool instead. These tools are usually more reliable and can often fix problems with formatted drives that don’t work with the PS4’s built-in format tool. ..
