Event Viewer in Windows 8.1 shows bad sectors

August 22, 2016 at 00:17:26
Specs: Windows 7
Hi

I have an HP laptop which has a single HDD. It has been showing about a dozen or more errors as below -
The device, \Device\Harddisk0\DR0, has a bad block.

After checking possible solutions on several websites, I ran CHKDSK C: /F /R /X which ran after system restart. It proceeded upto 13% smoothly, but at 13% halted for 2 minutes, and at 14% kept processing for over 45 minutes and instead of completing upto 100%, it just restarted couple of times and the system said it has completed the task 100% and then rebooted once more and showed my Windows login screen as usual. On checking the log entry in Event Viewer->Windows Logs->Application Log, in a "wininit" entry it showed the chkdsk details which showed only 4K in bad sectors, and no major issues otherwise.

Please note that I found Windows hang often about 10 days ago and chose to reinstall OS through Recovery process, which went off smoothly. However, these bad sector entries in Event Viewer have again cropped up and seem to make the system hang of and on.

Would be grateful if anyone can help me resolve the issue permanently. Of course, having the defective Hard Disk replaced is the last option, but I won't be able to migrate my Recovery partition to a new HDD, though I have Recovery DVDs.

Thank you.
Ramesh

Looks like your HDD is dying. Make sure you have a backup of your important data. If not, DO IT NOW!

It is still possible to clone your old drive to a new one so that your recovery partition is on the new drive. All depends how quick your old HDD deteriorates.

Thanks Sluc. Yes, I do have the data backup on external HDD as well as a 32Gb Flash Drive. So, no worries on data front. But, is there a free s/w to clone my current HDD with a new one ? Also, will the "bad sectors" on current one get cloned as well ?
A friend had helped clone the HDD on a previous Acer laptop, which seemed to clone the Recovery Partition as well, but when I replaced the new one with the old one then, it refused to access / recognize the Recovery Partition (though it showed 13Gb as Recovery Partition in Disk Management screen. Hence, not sure which Software you refer to, which will enable me to clone my current HDD to a new one, WITH Recovery Partition fully functional as well.
I do have the 3 DVDs I created as Recovery OS & Applns when I got the laptop about 1.5 years ago. So, hope those work properly and enable me to install Win'8.1 and all factory supplied Applns as well as a Recovery Partition on the HDD.

Bad sectors don't get cloned themselves but if there is any corrupted data in them it could either get lost or copied over. However, I have found that mostly there are no issues. There are no precautions you can take anyhow.

Always pop back and let us know the outcome - thanks

Thanks Derek. Also, came across EaseUS ToDo Trans free version online which claims to clone disks. When I read about it, it seems it copies sector-by-sector hence my query earlier whether bad sectors too get cloned.

Anyway, seems it would be safest to backup my data while my HDD is still working. Replace the HDD and install OS etc afresh using Recovery DVDs I had created when my laptop was new. Seems safest way to get both Windows 8.1 and my data safely shifted to new HDD.

In addendum to Derek's response, some disk cloning software won't always tell Windows the bad sector list no longer applies. After the drive is up and running Windows, you might want to run CHKDSK C: /B /X.

Most HDD manufacturers have a cloning utility to help you with a new drive:

Thanks Derek. But, I am considering getting the internal HDD replaced soon, and reinstall OS+ using the Recovery Media created when laptop was new.

Thanks @sluc and @Razor2.3. As many responses here and other forums talk of imminent HDD failure when Short DST fails, I am not willing to take chances, and have decided to get the HGST HDD replaced with a new WD / Seagate one, which are usually more reliable.

I agree with your choices except the Seagate drive. I have lost quite a few hard drives over the years that came with machines at home and at work. ALL of them were Seagate drives. Way back before Seagate purchased them I used Maxtor when replacing, upgrading, and building systems, since then I have used entirely western Digital drives. I have not had any other drives die on me and some of them were in use for over 10 years and there are a couple on old machines at work that are 15years old though I do not know what brands they are since I have no reason to open the cases except minimally to blow out the dust. All of my builds since my first custom XP machine have been WD Black series (one SSD drive now though).

You have to be a little bit crazy to keep you from going insane.

@Fingers - thanks for your advise and sharing your experience with Seagate drives. I too have used systems with mostly Seagate / Samsung / Maxtor (pre-IBM) drives. But, I observed that Samsung failed more often, while Seagate n Maxtor seemed more reliable - atleast serving well for 4-5 years. I have a Seagate Momentus 500Gb drive which I plan to replace with the current HGST one. HGST / Hitachi drives too have failed me in the past. For instance, this laptop I use is only 16 months old, and though I use it for about 9 hours daily, see no reason why a HDD should fail so soon. I am no IT expert and am not hard on my HDD (playing resource-hungry games or heavy multimedia stuff). Anyway, it's just electronics which can fail :-(
