If you have seen this message on your Windows computer, you should do certain things immediately.
1] Copy data from your hard disk to an external hard disk
Although you can copy files directly to the external hard disk, you can also clone the hard disk or create its image while troubleshooting is in progress. You need a new hard disk with enough space to store all the data while leaving a gap for work. Apart from the external hard disk, good cloning or imaging software would be necessary.

- /r : Identifies bad sectors and tries to recover information.
If /scan not specified /r implies /f.
3] Try Freeware data recovery
Some free data recovery software is known to help with data recovery unless the problem is physical damage to the hard disk. If they help recover the data, fine. Too bad about that.
If these tools help to recover data, try formatting the drive and check if it is now usable.
4] Connect the hard disk to another PC
If the hard disk is physically damaged, the probability of backing up all data is significantly lower. But an attempt to recover some files could be made by connecting the drive internally or using a hard disk box.
If files are accessible after connecting to an external PC, try to recover as many as possible.
Remember that a hard disk failure can be devastating and that such unreadable data sections can only get worse, so it is best to recover as much data as possible and change your hard disk immediately.
