download the disk checking tool from Western digital and run the tests.
If that comes back clean you should be OK.
However, you should have a backup anyway... even if it passes today - it does not mean it wont fail completely tomorrow/nextweek/next month/whenever.
If you are happy to gamble with your data... fine. But dont cry when/if it happens
As a rule, a hard drive will not announce it's imminent demise.
Another user on this forum had a similar message.
Consider the possibility that you may have a malware infection.
Do not click on any messages until you have eliminated the possibility.
Modern hard drives have s.m.a.r.t recording capabilities. You might check those statistics.
A hard drive will be overprovisioned with some spare sectors. If a sector goes bad, it will be reassigned to a spare. If the spares are nearing depletion, you may in fact get such a warning.
At the very least, protect any data you don't want to lose to some sort of an external device.
To repair, the hard drive, a full destructive reformat will probably work.
Perhaps this is a good opportunity to install a SSD for the os and some apps.
Here is your situation, the longer you continue to use your drive, the greater the chance that it will totally fail on you. Instead of spending time trying to run scans, checkdisks, etc... on it, get a new drive, make an image of your drive, and dump the image on the new drive. Unless you have current backups and want to see a drive failure first-hand. Your drive can run another 6 months, it could crash while you're reading this. Why take the chance?
I was working on a laptop drive that a user brought in after it started clicking. Instead of making backups of the files and replacing the drive right there, she used the laptop for another day. That one day cost her all her files because when she got the drive to me, it was unreadable by a computer.
are you sure that windows 7 does not have such a function, because it seemed legit and it offered me assistance in backing it up , not by 3rd party software but microsoft it self , and it told me to shut down the pc to prevent further damage? ..
