OK wow, just been getting... somewhere? I've been trying several drives, USB / HDD / SSD etc, and using various leads to plug in etc, but nothing worked. After reading the above, I tried a CF card - via a card reader, and USB to USB-C adaptor... and it worked! Green light on the ATEM and can record to drive.
I tried same card in a different multi-card reader (with multiple card reader slots) and this also worked. Tried some other cards in the multi-reader and these didn't work. Interestingly, when I plugged the multi-reader into my laptop, the CF card is the first drive to appear, so I presume the ATEM can only "see" the first drive slot if it is presented with an array of drives.
I noticed that the CF card default format was "exFAT" using 128kb partitions. I tried formatting the CF card as NTFS and it no longer worked. Now I've tried formatting it back again as exFAT with 128kb partitions and it's working fine again. I then formatted a HDD using these settings and now the HDD also works fine, green light and recording.
Maybe this specific format is required by the ATEM pro but it seems unintuitive not to show a relevant error message on the monitor.
