Hi, i have a 3TB Toshiba external hard drive. It is currently formatted in Ex-Fat done on Apple Macbook. The files (videos/photos etc) play fine on macbook but when i connect the hard drive to my blu ray player via usb port it does not play files. Can anyone help please? Do i need to reformat it in a different format? I understand MS Dos format does not let you copy files larger than 4gb which would be a problem as most files are 4gb plus.
