CHKDSK running really slow

Question

CHKDSK running really slow

Anonymous

Hi. I run Windows 7 on a fujitsu workstation.

I recently bought a 4TB hard drive (SEAGATE ST4000VM000 4TB PIPELINE HD).

I’m going to use this HDD on another device, not my PC, but since that device cannot format that kind of volume, I installed the HDD to my PC.

I needed to make an EXT3, GPT format to make the HDD ideal for my use.

I tried to do so with a program called “EaseUS Partition Master 10.0”. Then it get stuck to 46% (maybe that was my second attempt, after I cancelled the first one), so I tried a couple of other programs (Seagate DiscWizard and MiniTool Partition Wizard Home Edition 8.1.1). After these programs failed to do the job also, I tried on windows.

I’m sorry to tell you all these details, but they might mean something.

So I formatted that drive (new empty drive) with NTFS, GPT, and simple partition. Because It still get stuck at 46% when I tried to make it a EXT3 afterwards, I stopped trying EXT3, and I tried to check that HDD for errors.

So I run “chkdsk /R F:”, and chkdsk is now running on my PC, on a single 4TB volume NTFS.

But that started at 26 Jul 2014, and now three days later it is still at 17% scanning free space (81 595 742 of 976 669 653) that is 8.35% of my free space.

It is working, and numbers are changing steady, but really slow.

I simultaneously run a “chkdsk /R D:” on my other HDD to see how it goes, and when it went to “verifying free space” the speed was at least 100 times faster (instead of the digit of thousands changing one every one second approximately, it was the digit of 100 thousand changing almost the same way).

Any suggestions, so I won’t wait 30 more days for chkdsk to finish?

I tried to run SeaTools, but it didn’t run both windows and Dos version.

Finally I understood that Hdd had many bad sectors, and chkdsk wouldn’t solve them.

So I gave that HDD back, and took another, and so far so good.

Thank you everyone.

Hello Vourosp,

Thank you for the update on the issue.

I would suggest you to run SeaTools for Windows to ensure there are no corruption in the hard drive. If the drive passes SeaTools for Windows, your troubleshooting can move to other areas.

Refer to the article: SeaTools for Windows

Hope this information is helpful. Please do let us know the result, we’ll be glad to assist you.

Thank you.

Hi, and thank you for your answer.

I'm sorry, I already made changes before I read your replie.

At this time I did the following:

I used the "Gparted-live-0.19.1-1-i486", and saw that the format in NTFS is always "Quick", while EXT3 is slow. So I managed to make EXT3 format entire disk except a small portion of 69.42 GB from 3,726.02 GB total.

This part made "Gparted-live-0.19.1-1-i486" crash and my PC did reboot. So I think there is the problem that I have, so:

I formatted NTFS this section located in the middle of the disc, and let "Unallocated" the beginning and the end of it.

After I started Windows, and now I run "chkdsk /R E:", to fix errors in this section only.

Big difference than I did the entire disk so, but again, right now I'm at 1'594'165 of 18'176'273 free clusters after 4 hours. At this rate 69.42 GB will need a total of about 46 hours. Of course I see that the process is much slower, I believe due to errors on disk.

Hello Vourosp,

Welcome to Microsoft Community Forum.

Did you make any specific change in the computer prior to the issue?

Try removing other external devices and check if CHKDSK is still running slow.

If the issue still persists, try running CHKDSK through safe mode and check if it is still running slow.

Refer to: Start your computer in safe mode
