Current Pending sector count errors after shutting down PC while updating

[cykamancer]

So I will try to explain the situation to my best.
Windows 10 was updating while my computer lost power and shutdown due to power loss.
upon next boot I find chkdsk started repairing the disk but never completed(over 8 hours).
So I reinstalled windows 8.1 on that drive deleting the windows 10 completely and now Crystal disk info shows I have some current pending Sector counts. I have run chkdsk many times and it doesnt find any errors.
What do I do to fix it? there was no errors prior to the windows crash while updating. some people suggested a full format of C drive but is there any other method of fixing it?
I can read all the data as of now...please see the screenshots below...also the drives are fairly new

Hi there cykamancer,

Sorry that you are facing some issues with your WD drive. 🙁
My suggestion would be to back up all the data stored on the drive.

Is this your OS drive? Sometimes, the zero writing process helps when it comes to pending sectors. So, you can use some writing zeros tool(full erase) and reinstall OS. Keep in mind that this is data destructive and you need to back up the data stored on the drive before that.

After all this, you can retest the drive. You can run both short and extended DLG tests as well: http://products.wdc.com/support/kb.ashx?id=9APYlE

Is the drive under warranty?

Let me know how this goes,

Hey thanks for replying!
I have to check whether its under warranty or not.
and Yes this is the OS drive with 3 partitions C,D and E. when my windows crashed while updating i tried to access the drive using another windows install on another PC . I couldn't access the C because it said it was corrupted and need to be formatted so I just quick formatted it. HOWEVER the D and E drives opened seamlessly.
And right now I'm within the same drive in question with my windows running in C drive.

My question being that If I dont do the zeroes thing and then my OS starts writing to that supposedly "bad" sector then will it just overwrite the previous corrupt data and work fine??

I don't think that OS will write on that weak sector. It could become reallocated with one point.
In case you write zeros, and this fixes the issue, then these are some logical bad sectors. If you write zeros on the drive and the issue persists, then these would be some physical ones, and you should consider replacing the drive(or using it for storing non crucial data).

Okay I see. I highly suspect these are logical. But are there any way of knowing that in which partition the weak sectors are? I mean the windows chkdsk finds nothing wrong but other 3rd party does. I have huge data in partition D & E. does writing zeroes delete the entire drive or just the C partition?
and another question being...how can I run chkdsk on the recovery and system partition in windows 8.1? they dont have any drive letters as such and are hidden.

Well, not really sure you can see where are these located. There could be some third party tool that can do that, but I'm not aware of it.
The writing zeros completely wipes the whole drive(writes 0 value in each sector).
You can go to Disk Management -> right click on the partition -> Properties -> Tools.

Hello Sir.
So yesterday night I did a full format(not the quick format) only on the partition C: of my WD drive and reinstalled windows and also did a full surface test with Hard Disk Sentinel and it did not find any bad sector.

So now can i be sure the drive is fine? I have 1 month warranty left but don't want to really lose the data. the crystal info shows this :

Well, it seems that these were some software errors that appeared as a result of the unexpected shut down. So, I believe that the HDD is fine. Yet, even when a given HDD is fine, you should always keep your most important data backed up.
If these were some physical bad sectors(on the platters), the reformat wouldn't have helped.
