My laptop HP Pavilion zv6000 I got from my friend works just well, but there is a problem, the HDD Toshiba MK8025GAS is too noisy. In a quiet room, I’m always irritated by that freaking noise. I know that is from HDD because of the clicking sound every time I open a file, a program, search files … However, it seems to be strange that now I notice that noise more intensively than before, so I perform a lot of test for errors and bad sectors, some reasons that may cause this. The first is CHKDSK tool.
Open Command Prompt and type chkdsk /f /r c: ( or any partitions ) You’ll say that you can get the same result by right-click on your drives - Properties - Open Tool - Error Checking … choose Automatically Fix File System error or Scan for attemp recovery of bad sectors … but you can have more options by other parameters like /i and /c .
Secondly I use Defragmenter tool. After that my Windows performance speed is faster, really, cause a lot of file is fragmented. But the noise is still. 
I download and try HD Tune and HDD Life. The HD Tune error test actually found some bad sectors on the beginning track of my HDD, and HDD life warned something about spinning count and threshold. Since that is just a report and they can’t do anything to repair, maybe it’s belong to physical damages, not file structure.
And I found a great tool in Hiren Boot CD , HDD Regenerator 1.5.1 , which can perform some special task like repair bad sectors and even physical bad sectors. Yes it really worked since it detected and repaired while Windows Chkdsk or other tools can’t. But the main problem still exists.
