Is bad clusters means bad sector?

[kkecin]

Hi! I'm currently new here. First of all, i'm an amateur to the technology.
So, i got the secondhand Dell Inspiron 620MT with the specs:
Intel Core i5 2400
RAM 4GB DDR3
1TB HDD
Powercolor AMD HD 5400 series
Windows 10 64-bit

few days ago i tried to extract some rar file and it always stucked at 22% even after i tried to cancel and delete the file then retried to extract it.
And when i running disk defragmenting it says some error occurred but when i running disk error checking it said my drive worked fine. After i restarted the pc, it shows preparing automatic repair then diagnosing your pc but after attempting repair, it said automatic repair couldn't repair your pc (i got some preparing automatic repair loop before) then i tried the tutorial from youtube :

After that i pressed exit and continue to windows 10. And it come back at preparing automatic repair again and i retried that tutorial again but change the MDBackup with MDBackup1
after finishing the tutorial i'm not immediately exit and continue to windows 10 again but instead i run command prompt again, running sfc /scannow, then dskchk.

On stage 4 of dskchk, windows replaced bad clusters in file. After all of chronologies above does it means my harddisk is get some bad sectors?
Here a pic of current progress



I might provide more information if you guys asking me but limited to my knowledge okay?
Thank you for your support.

Yes bad Sectors is the same as bad clusters. Looks like you've had 4 so far but windows is able to reallocate them which means spare ones have been mapped to be used in place of these. If you have had many, consider replacing the drive. And please be sure to have backed up any important data ASAP!

Well you should really have backed up your data whilst everything was working okay. Now you'll have to connect the drive to another computer to copy your data off it.

Do you have valuable DATA on this hard drive?
What is hard drive manufacturer?
And do you have another PC (proffered) or Laptop? If yes, which one? For DATA recovery....

You can use a bootdisk (cd, dvd, flash drive) and browse to the files that way to make copies onto another device, such as an external HDD.
