      I'm not sure if it's running. When I run df as per the docs for manual mounting I can't see my hard drive either, which is very weird since as you say, it copied the ROMs over.

      I have just spotted an error as I rebooted the pi, it said:

      Failed to start Usbmount@dev-sda.service

      Which sounds curiously relevant! Any ideas what might cause that?

        Run sudo systemctl status ubmount@dev-sda.service and see what errors are reported.

            Does manually mounting the disk works ?

              I'm not sure how I can do that if the commands the documentation say to use don't show the disk? When I use df it doesn't show.

                @2fst4u dfonly shows the mounted filesystems, it doesn't show all disk devices. If your disk is not mounted, then it will not show up in df's output.

                  Right, what command should I be looking to use then? What can I use to see the device before it has been mounted?

                    @2fst4u You can query the device with fdisk, to see the available partitions

                    fdisk -l /dev/sda

                    then mount the corresponding partition under a temporary mountpoint

                    sudo mount /dev/sdaX /mnt/

                    The name of the device should apper in the log, immediately after you plug in the drive:

                    dmesg | tail -n 20

                      Ok cool, that seems to have worked and it's telling me there are some issues:

                      Could this be the reason it doesn't want to mount it automatically?

                        @2fst4u Looks like the hub/usb disk connection is reset

                        You could try a check of the filesystem (on your PC) and see if it produces anything.

                          @2fst4u A lot of external hard drives the 10-pin usb port is easily damaged, and will make faulty connections unless carefully situated. Which is awful engineering.

                            Ah what an absolute prick of a thing! @mitu thank you for all your help so far, you've been great. I think you hit the nail on the head, @Efriim! I removed the hub from the equation and now it's working properly! How bloody annoying.

                            I went to all the effort to use an externally powered hub and it ended up being the problem haha. Thankfully the power supply seems to be able to power both the zero and the HDD directly through the USB port just fine so now it's working as expected.

                            Tl;dr - if you have this problem check the hub isn't causing it!

                              @2fst4u To be fair, this is the most common problem when dealing with a Pi Zero - the hub. Glad you got it working.
