DISK CORRUPTION PROBLEMS – Bad block – CHKDSK
Running Windows 7 pro on a Dell 7010 computer. There are 2 usb drives connected to the computer. Lets call them D1 and D2. The office staff removes D1 on Monday and attaches D2. On Tuesday they detach D2 and attach D1.
This is causing data problems. When I attach either drive , Windows states the drives need to be fixed.
I ran chkdks D1 /v /f and CHKDSK said I had to use the /r switch.
Q1: The usb drive capacities are 4 terabytes. The chkdsk /r has now been running for over 3 hours. There seems to be no way to interrogate CHKDSK to determine how much longer the repair process will take. How can I determine whether CHKDSK is repairing the drive or whether it just got stuck and is doing nothing?
Q2.) I ran Event viewer. It reports the usb drive has a bad block (error 7). What should I do now?
- Run DISKPART? And destroy all data?
- Let CHKDSK run ?
- Something else? Please give me detailed answers . I am not a computer expert.

i also found that the latest windows 10 versions require a chkdsk to be run - everytime you connect any disk drive
i never found a solution for this - it seems a new windows strategy

Q1: There is no way that I know of to interrogate CHKDSK progress after it has started unless you used the /v (verbose) option. That will display the name of each file as it checks it, and will give you a good idea that it is moving.
Q2: You've got a few issues to consider:
a. You may have a one-off error, or you may have a drive that is beginning to partially of fully fail. If you don't have a good recent backup of anything critical, make one before going any further. That way if you have additional problems, you'll have saved the maximum amount of data.
b. If you start to encounter multiple errors, and your data is valuable, you probably want to shut the system down and contact a data recovery company. Continuing to operate a failing HDD can cause further damage, depending on the nature of the problem.
c. Some data on disk may already be corrupt. If the drive is failing, replace it. If not, after running chkdsk /v /r identify any files that were damaged, and replace them from a recent backup or other source (reinstall or repair an application, driver, Windows component, etc.).
In the future, consider using some sort of hardware or software disk redundancy for valuable data: RAID 1/5/6. This way you can tolerate a drive failure with a drastically reduced risk of data corruption.

My concern right now is about the internal Western Digital 4TB Datacenter WD4000FYYZ drive.
When I started the chkdsk operation the instruction I used was chkdsk e: /r /v
The chkdsk has been running about 72 hours now. It has not finished.
The data on the drive does not need to be saved.
So I guess the actions I should take are:
- Stop the CHKDSK operation
- Reboot the computer
I’m not sure what I should do now.
The drive letter is D
Q1.) Then should I uncheck “quick format” and format the drive ? Will this perform a low level format and map bad blocks?
Q2.) Or should I run fsutil ? I assume the command to run is : fsutils repair set D:1 << is this correct?
What would you do?

@marnold - i have it when connecting good known disk drives on W10 systems - i'm not sure how it would have a dirty bit set - maybe you can detail that further?
You can test see
https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/fsutil-dirty
The issue might be related how devices are detached?
Just something to look at.

i know that command - but i wonder how comes the bit is set - when it's a good disk
i must say it always terminates dskchk in very short time - and never reports anything wrong

Several Possibilities. The bit might get set after several attachments of the external disk.
The other is an unclean detachment.
The third is a combination of things.including on connecting the external storage, the interaction between the OS and the USB to the Drive is seen a fault.
Use fsutil to clear the dirty bit. Go through the steps of unmounting the USB storage.
and see whether the next time you attach the usb storage, whether the dirty bit gets set, and/or whether the chkdisk runs.
commonly, if the chkdisk is allowed to proceed.(commonly it has hit any key to terminate the running of the check disk,)
As is common when one is not expecting the prompt, is to start typing whatever they were planing, not noticing the termination of the check disk.

Dr Klahn: I have never used the SMART utility. This is all new to me.
So I found this web site:
https://www.howtogeek.com/134735/how-to-see-if-your-hard-drive-is-dying/
I'm assuming the information in this site is accurate . I will run the SMART utility and report the results.

I forgot to mention I will run the SMART utility on the internal disk drive:
The internal Western Digital 4TB Datacenter WD4000FYYZ drive.

Installed the WD Data Lifeguard software. I ran the SMART test and the Quick test. The report is in the attached PDF file. The quick test never finishes . What should I do now?

Thank you, arnold, that's what I need to know. It was purchased about 10 days ago so I should be able to return it.
QUESTION: When I installed this drive I performed a quick format. When I get the replacement drive, what factors do you consider as to whether a quick format or a full format should be executed?

Thank you all for your prompt answers. I really , really appreciate your help. Disk problems are out of my realm of knowledge.
I have sent the drive back to the vendor and have requested a replacement.
