I am trying to restore media from an external drive to another external drive now both the partitions have been formatted with the same partition map GUID partition map (I am also getting an APFS partition message on clicking the partition map option available under disk utility)). Now whenever I am trying to restore the partitions, I am coming across several errors.
This was the first attempt: I selected the main volume (as the source volume from which the media files are to be restored) which is at the top of the volume tree (Sandisk Ultramedia)
I am facing this error! (I have attached some screenshots to further explain my problem)
This time I selected the volume within the container APFS volume (as the source disk from where the media files are to be restored) which is the Sandisk USB External Drive/MacOS USB. But, again I got the same error.
