Solved Checkdisk problem, please help!

July 21, 2016 at 13:58:08
Specs: Windows 10
I ran chkdsk /r on hard drive which got some bad sectors and this is screenshot for last moment before i stopped chkdsk. http://i.imgur.com/qhgyZ8Z.png

I canceled chkdsk after ran some minutes because i heard run chkdsk /r on hard drive with bad sectors can lose data.

So according to this chkdsk prompt window screenshot, was that possible about that data was removed/fixed or anything changed by chkdsk? i am asking about that chkdsk could do something to data even no errors are found on prompt window, did i lose data by chkdsk in this situation?

From your description in #4 then it won't have done anything at all.

But I must again say that if chkdsk ever has to do anything it is because the data is already damaged. Even if it finds and fixes bad sectors It doesn't lose any usable data or make anything worse.

If the hard disk is about to fail then doing "anything" on it could cause data loss including chkdsk and defrag which stress the disk more than normal use. This is problem with the disk not chkdsk.

Always pop back and let us know the outcome - thanks

If a hard drive has bad sectors then the data in those sectors will be corrupted whether or not chkdsk /r is run or not.

The questionable item is the hard drive not chkdsk.

EDIT:
I now see that you have already posted this question and received answers. Why did you post it again?

Oh, i forgot that i posted this problem before. i tried but could not delete duplicated post. i am new on computing.net, that was my mistake.

And, i know data on bad sectors are already damaged. actually i coped all data from disk with bad sectors to new drive except some files which could doubt as corrupted.

One thing i wanna know is, because i copied all data to new drive after stop chkdsk and that is last chkdsk prompt before i canceled.

So i just wanna know chkdsk did something to data or not in this situation.

In terms of what you posted in the link then it did nothing - it just looked for issues but found none. I don't know what came before your link so can't comment about that.

However, in general, although chkdsk /r can remove data from the user (by preventing access to bad blocks) it matters little because anything it removes will be corrupted and therefore unreadable anyway.

Always pop back and let us know the outcome - thanks

Seems my English is so bad to understand your answer.

So let me ask point like this finally, i uploaded screenshot from last chkdsk prompt window before i canceled.

As that screenshot, i stopped chkdsk at stage 4 with no errors found(reported). also 1~3 stages completed with no error found(reported) too.

I judge what chkdsk did by prompt window says. just worried if data loss is possible cause of chkdsk /r even got "no error messages"

Then can i be sure that chkdsk didn't do anything to data in this situation?
