linux - Cloning Raspberry Pi Image to External Hard Drive on Mac

Hi I'm looking to clone my 64gb microSD card (formatted as FAT32) for a Raspberry Pi to an external hard drive. I have the microSD inserted to my Mac and is /dev/disk2. I have the external hard drive also in my Mac as /dev/disk3s2. This error message shows


Erics-MacBook-Pro:Desktop $ sudo dd if=/dev/disk2 of=/dev/disk3s2/gnuradio_cmake.dmg
dd: /dev/disk3s2/gnuradio_cmake.dmg: Not a directory

I've tried to both mount and unmount disk3s2 to no luck. I've considered creating a new partition on the external hard drive that's formatted to MS-DOS (FAT). Would this potentially work or is some other action necessary?
