My passport ultra 2TB hard drive is inaccessible and I am unable to reformat. How do I re-format MY Passport for PC so that it will work with Mac and PC? I recently purchased an Apple MacBook Air and also have a Dell laptop. My Passport is serial number WXM1C5294201. Please make sure all the 4 corners are included in your scan Please make sure the passport is flattened when being scanned. Please scan your passport to PDF or JPG format in high resolution. If you don’t have a scanner at home, you can use the business service from stores such as Staples. Please use a scanner to scan your passport.
