Hello, hddgurus. Excuse me for my English, I'm good in reading but not in writing.
I have some Samsung HDD, which has clicking of the death.
I connected to its Serial Diagnostic Port and have this messages:
Code:

Then we opened HDD to view a VCM. There was some small lever, that should open a pass (it try to) for heads. But it can not do this and as following it stuck heads.
So, I just pushed it a little bit, so heads can move on. After that I had this output from serial terminal:

Can someone explain this output? Thank you very much.
