Ran a test with HDTune and found 0.2% of my drive had bad blocks. It's a 1TB drive, a Seagate Barracuda HDD from about 2011 or so. Probably 5 total red dots on the test.

I noticed performance was odd on this drive, which prompted me to run the test. There was also some corruption noted when I ran chkdsk.

This is a secondary HD that is used to store Data, which is regularly backed up. Should I consider this drive too big of a risk at this point, or is there a way to quarantine the bad blocks?

Would love to hear some recommendations on how to proceed.

Thanks!

As the prior poster said, once the drive starts to exhibit hard errors of the disk platter of the hard drive in question.
You should use another drive and back all of the data up on the drive.

Hard disk drives have what we call spare sectors as a redundancy if any part of the disk platter starts to produce hard errors on the platter.

But the spare sectors are not finite, once the spares are used up to move data where the disk platter has hard errors.
Data is then lost for good on the bad sectors of the drive.

Windows it`s self should flag the bad sectors if they are hard errors of the magnetic disk platter unable to be written, or read from by the drives read and write heads.

If you intend to keep using the drive then, use it to...

Well when I was in school my instructor always said the moment a drive starts throwing errors or showing bad sectors regardless of if you quarantine the bad sectors any important data should be backed up and moved off the drive and you should assume the drive could die at any moment. If your drive is full of unimportant stuff I probably wouldn't worry about it, but if any important data is on that drive I would get it off immediately.

If you intend to keep using the drive then, use it to store data you are not bothered about loosing, other than its use for important system backing up Podonnnell.
