 I have this hard disk here which is no longer working and out of curiosity, I opened it and this is how I found it with the head here, parked here. And I put on this small sticker so that you can see the disk spinning when I power it on. So you heard that noise, it's the disk that tries to spin but it doesn't. Let's switch it off again and now when I move the head all the way off the disk and power it on it will spin like this. And now when I move the head back all the way over there and I power it on it will try to spin like this and now it is stuck again.
