I had taken a back up of files and folder on the external hard disk. Then I formated my hard disk. I copied all the folders and files back from the hard disk to PC but I am not able to copy back one folder nor the files in it from the external hard disk to my PC. There shows an error [Cannot Copy Change of Adress : Access denied, make sure the disk is not full or write-protected and the file is not cuttently in use]. Plz help me on this error.
