Is it a physical HD (magnetic) and making noise? I had one years ago (fortunately my only failure so far) and if I kept persisting to try and read it via a USB recovery drive, I managed to pull enough data off that was important. If it’s a newer SSD, that’s a different thing. Doesn’t mean all the data is gone, just a lot harder (read $$$) to pull. Hopefully it’s just software or a loose cable.
