as far as I know FAT32 should be the file system you use. I do not have any black magic camera but as far as I know there is not a camera on the market that uses Mac file systems.
First I would try to narrow down what is causing the issue. Since the SSD seems to work correctly in the camera this indicates the camera and SSD are working correctly. The only other variable is the 3.0 doc you are using. If you have another SATA to USB cable or can connect the SSD internally (like on a desk top) see if you can view and transfer the data using some other way of connecting the SSD. It is possible the doc is what is causing the system crash.
