You shouldn't need to change permissions to copy from the drive, only make changes to, but you can't, as the Mac can not write to NTFS disks, only read. The only way you would get a permissions error trying to copy from the hard drive is if you are trying to copy the files to a place on the drive you do not have permission to do, like someone else's folder, or in system made folders. Do you get the error if you try copying to your documents folder?
