To fix a hard disk CRC error, run the CHKDSK application. In the "My Computer" folder, right click the affected hard drive and click properties.

(In most of the cases this doesn't work because from GUI It won't show all the properties of the disk; It will end-up without doing any disk check. The alternative to this step is execute commands from command prompt as below:

1. Run CMD as an Administrator
2. type chkdsk G: /f /r ( 'G' signifies the affected Drive). This utility would take long based on size of the disk and no of affected sectors.
3. Run DiskPart utility from the same command prompt type DiskPart
4. Once utility is loaded run "rescan" command. This command locates new disks that might have been added to the computer.

5. Hopefully problem would be resolved and you would be able to explore your disk. You can trace the logs of chkdsk utility from Right click on

     'My Computer' -> Manage -> Event Management -> Application logs. 
      No need to follow below steps.
   

Enter the "Tools" tab and click the "Check Now" button. A small windows will appear, make sure the "Automatically check for filesystem errors" box and the "Find and repair bad sectors" box is checked. Then click start. You will be informed that you need to restart the computer to perform the check, click the schedule check button, then restart the computer.
