I have the same problem

If the data on it is valuable to you, DO NOT open the lid, DO NOT play with it DO NOT send commands to it
As a matter of fact do nothing except than sending it to a DR pro I repeat a DATA RECOVERY PROFESSIONAL ONLY (not to a computer repair shop/computer tech).

I don't have any important information on it,I buy this hdd because I want to unlock it and sell,I have ttl adapter and when I connect this hdd on it and start terminal hdd send me this message.And when I run script hdd send me "COMMUNICATION PROBLEM.SCRIPT STOP

LED:00000047 FAddr:060BE178

It is a Seagate, DM Series, and has already presented problems.

Just dump it, or sell as defective/for parts. Any "cosmetic" thing done to it would be just a scam.

Where I have to jump on this board?
This is seagate momentus 7200 fde.2
