I have a 2TB Toshiba portable hard drive. It has my movies (avi, mkv, mp4, etc.). When I plug the portable hard drive into my DVD player, ( I have two that play off of the portable hard drive), it is recognized and plays. But, when I plug the portable hard drive into my computer and try to access it, to add more, a box opens that says it is "not accessible". " Access denied". It was fine yesterday. How can I get access to the portable hard drive so I can either put shows on another hard drive, or add, or delete my shows? Can anyone help? I would appreciate any help. Thank you.
