Windows 10: Chkdsk destroyed my blockdevices

i was using a dualboot configuration, until an ntfs drive that i use to share files between two system start to give 'Input/Output Error', so i booted into windows, runned Chkdsk on my drive, booted back into my main system, and what i see? 2 of my blockdevices is corrupted but still accessible, and one is completely dead0 bytes in size, what happened? why Chkdsk destroys a file that doesn't harm anything it just a blockdevice file that formated to ext4 and used as loop device, i lost so many things, in that blockdevice that absolutely dead, there a bunch of my docker servers data, from back

:)

 

chkdsk c: /F

It might be an error on the drive. We suggests that you follow the troubleshooting steps below:

• Run Disk Cleanup utility to clear your junk files.
• Open an elevated CMD type sfc /scannow and hit Enter to run the System File Checker.
  
• Once the scan is completed, restart your computer. Remember to exit ChkDsk
  during boot.
• Next, again open CMD as admin type
  Dism /Online /Cleanup-Image /RestoreHealth and hit Enter to repair the Windows image.
• Now see if ChkDsk able to complete the scan.

Note: Before doing the steps, make sure you save a back up of your files.

Let us know how it goes.

CHKDSK ruined my drive

chkdsk destroyed the file system integrity on the fresh-from-the-shop new drive containing a raw copy of the old failing one. There were few timeout errors in phase 4, but they were likely a system glitch or something. Moreover, chkdsk stopped with two strange
errors which I suppose were internal crash reports.

Now I ran CHKDSK /X /F /V /R /B on another partition, and result was the same: few errors during step 4, two final chkdsk errors (supposedly crash reports), and damaged file system integrity at the end.

I think something is wrong with CHKDSK /R /B.

Now I started raw copying again and will avoid this mode next time.
