Recover Photos from LaCie Drive

My old LaCie external drive still mounts on my new Mac Studio (Apple silicon), but almost every JPEG stalls or throws an error when I try the usual drag-and-drop. I have not run any recovery utilities yet, so the disk is untouched beyond those failed copy attempts...
