"The device, \Device\Harddisk0\DR0, has a bad block."
I saw this error in my event viewer today and realized I've been getting it multiple times throughout this month. What do I do about this? The hard drive in question is only a couple of months old, why is it already failing?

Hard drive is damaged/dying.
Save as much data off it as you can, then contact manufacturer and ask for a replacement, if you can. If not buy a new HDD/SSD.

No clue why it's failing, I don't know how you treat or use your hardware.

Do an emergency backup dump and then run chkdsk /r

The only time I can think of where any hardware might've been physically damaged is one time when my dog knocked it against the wall (it's on the floor), but it didn't like completely fall, it hit the wall on the corner of the case and started leaning against it

that could also be a bad sata cable, it happens

check the smart status of the drive with aida64 or hdtune

I just finished scanning my hard drive with a program and found it has two bad sectors on it. Guess the multiple errors in event viewer were picking up the same two instances.

once a hdd starts showing bad sectors, replace it asap
you dont have long before it fails

any pending or re-allocated is a sign to start looking
when flagged as bad is when the drive will start losing storage

I try to use built-in Windows stuff whenever possible. :steamhappy: So to confirm or for future reference, (check for corruption and bad blocks) you can open Administrative Command Prompt and copy/paste this:

chkdsk /r/f

The /f argument will attempt to fix the corruption. A message that the drive is in use will appear, type Y for yes and restart machine. The scan will start and it may take a long while, depending. When it's complete, find the results in Event Viewer/Applications.

Will reformatting my hard drive fix bad sectors on it?
https://superuser.com/questions/61899/will-reformatting-my-hard-drive-fix-bad-sectors-on-it

Most hard drives made today (referring to consumer drives) are manufactured in such a way that they really only just work. The drive manufacturers add extra bits so that the drive can compensate the gradual loss of these writable bits.

If you really want to resolve the drive then an application like SpinRite will attempt to read all the data from the current sectors and probably is the number one tool used by skilled data recovery experts short of using a clean room and putting the platters into another piece of hardware.

So in short a low level format may help re-find bad sectors and mark them as such but it would be a waste of your time and effort on a modern drive (eg: post y2k). Using SpinRite may help in data recovery and helping find other sectors that are starting to degrade.

Like Jason has said, once you have moved beyond 5-10% of the drive having bad sectors, its time to no longer use this drive for data that you wish to keep.

chkdsk does not show the smart status of the drive
the drive knows when its gong bad and logs it in the smart table

windows default tools dont look at it

As I said, the drive only has 2 bad sectors on it right now. I ran chkdsk /f /r and it went through the entire drive after 2 hours. If I get more events saying there are bad blocks, I'll just get a new one

every time you check it it will grow

bad sectors are like rust, they will spread
