Hi, hoping someone can help with what’s best to do. I have one portable seagate HDD 2tb hard drive and one seagate expansion desktop drive HDD 2tb that have both stopped working. When I plug them into my MacBook they will make a mechanical jamming sound every second or so. They won’t appear in finder or even in disk utility so I have no way of accessing them. How do I fix this? Tia! I’m based in the south of England if that’s any help :)
