So I installed NTFS for Mac to regain read right permissions to a Toshiba external hard drive that was originally formatted with windows NTFS. Installation was fine but when I mount the drive it still mounts as read only and I'm Unable to figure out how to regain read write capabilities without having to erase and reformat the drive. Any help would be greatly appreciated. Thank you. I just want to regain read right permissions to the drive without having to erase and reformat.
