It is unusual that mounting with the 3B+ worked without a partition table. A partition table must be on every hard disk, otherwise the OS does not know how much space there is and how it should use it. Without a partition and formatting, this usually doesn’t work. So it is normal that you need a partition table to mount the hard drive, even with the Pi 4b 8GB.
