Buy a new hard drive ASAP and move your data off the failing device. In the meantime, make a backup of critical data.

I have backed up my data ,is there any method i can save the drive,if i plug it into a computer and format it and then again install windows,would it be of some help??

You could attempt to replicate clean-room procedures and replace the failing hard drive platters. It is highly unlikely that you will be able to obtain replacement platters, replicate a sufficiently cleanroom environment and work at the minuscule tolerances requires to assemble a hard drive and head assembly. Even then you'd have a half-asses repair job with loss of data. It's not worth it when hard drives are so cheap.

Hi there tanmaymishra88,

Sorry that you are facing some issues with your WD drive. 🙁
Unfortunately, it is in a really poor condition.(around 500 bad sectors)

Keep in mind that all the thing you can try, require intensive reading/writing, which could kill the drive even faster.
Yet, if you want to, you can attach it to another computer, reformat it and re-test. See if there would be any difference in the results. You can even write zeros with WD's DLG tool. That is a process that fill in 0 value in each sector.(retest afterwards) The data would be unrecoverable. Be absolutely sure that everything is backed up.
