About chkdsk function

[SinOnK]

I ran chkdsk /r on hard drive which got some bad sectors and this is screenshot for last moment before i stopped chkdsk. 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.

No, i checked. 'chk' files or 'found.xxx' folders are not created on this drive. then nothing happened?

Nope, it didn't make any changes then. If you want to check disk properly, find your make and it's test utilities here: http://www.majorgeeks.com/mg/sortname/hard_disk_drive_(hdd)_tools.html

I saw some people says data loss is possible without making chk files or found.xxx folders. some of their case says data is not changed to chk files, just deleted after chkdsk. i am curious if this is possible in my case, while i running chkdsk there are no any error messages on prompt. about this, i found answer that if chkdsk founds no errors (no reports) = it didn't do anything to data. i wonder just this is trustful or not...

If you run chkdsk without any parameters it will only check for file/data/file system corruption without changing anything.
chkdsk /r does the same thing as chkdsk /f only it also checks for bad sectors on the disk and recovers any readable information. Running chkdsk /r implies that also chkdsk /f is run.

chkdsk /f only checks for disk errors, not bad sectors.

Microsoft has a detailed page for chkdsk.

So conclusion is... according to that prompt results, chkdsk didn't do anything to data in this case?
