Hi there shashank11701,
Sorry that you are facing some issues with your WD drive.
This should be a secondary drive right? Do you have some important data stored on the drive?
In case you don't, you can clean the drive through command prompt -> go to Disk Management -> repartition and reformat the drive.
So, you can:
- Open CMD
- diskpart [enter]
- list disk [enter]
- select drive [number] [enter]
- clean all [enter]
It will not hurt to test the drive afterwards. You can do so with WD's DLG tool(both short and extended tests):

Let me know how this goes,
