What can I do if the hard drive is making clicking or strange noise?
You will not heard the strange clicking noise from the hard drive if it works well. So if it start the make the noise you will need to pay attention about the data storage. Please stop saving any new files on this hard drive and start moving the original data to a new one.
Also, if some files are unable to read due to the physical damage, you will also need to launch Hdata Recovery to scan and recovery such files, save all these files on a new hard drive to keep them safe.
