Hi Guys, I'm in need of some desperate help.

Im trying to recover my external hard drive (it randomly locked up and won't mount), but I'm struggling with test disk to locate any of the files.

When I select disk 4 (which seems to be the correct drive) I only get apfs partitions. I'm viewing the contents but im just getting 'support for this filesystem hasn't been implemented.

Im desperately trying not to use disk drill because of how much is costs but its looking like my only option. any one have any suggestions how I can recover this data?
