My external 3TB Seagate Barracuda HDD suddenly started to have a clicking noise when powered on. After about 15-20 second of clicking, the drive powers off. The clicking noise started happening after I powered on the computer after a cold shutdown, without waiting enough time to let the platter stop moving on the HDD. I have tried two other power supplies without success. Also, the weather has been hotter than usual during the last few weeks.
1. Is there a test to discover the cause of the problem?
2. Is there an at-home fix? Replace with a donor PCB, or open the case and move things around (without a clean room)?
3. Do you have any data recovery references or recommendations, etc?
Any help is greatly appreciated. I have a lot of very important data that I created on this HDD. I am mechanically inclined, with enough experience to try fixing it myself, with your advice and guidance.
Thank you in advance.
