How to Fix a Cyclic Redundancy Check Error
A Cyclic Redundancy Check (CRC) is an error checking technique used by computers, specificallythe hard drives or optical disks (i.e DVD/CD). A Cyclic Redundancy Check error is caused whendata on the hard-drive or DVD becomes corrupt.
Check the cause. In the case the CRC error was thrown by the hard drive, the cause islikely data being incorrectly written to the hard drive. This can be caused by either theoperating system being corrupt, or a power loss.
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.

3 properties of the disk; It will end-up without doing any disk check. The alternative tothis 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).
3. Run DiskPart utility from the same command prompt type DiskPart
4. Once utility is loaded run "rescan" command. This command locates new disks thatmight 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.
#*You will be informed that you need to restart the computer to perform the check,click the schedule check button, then restart the computer.
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 badsectors" box is checked. Then click start.
Note when it can't be fixed. In the case that an optical disk (i.e., a DVD/BD/CD disk) isreporting a CRC error, there is no way to fix this. If you burned data to the disk yourself, tryburning said data to another disk, this time at a lower speed. 4x is the recommended speed,especially when burning operating systems (i.e an Ubuntu LiveCD) to a disk. The higher thespeed at which the data is burned, the higher the chances errors may be written to the disk.

Disks may throw CRC errors if there is a smudge or scratch on the disk. Try cleaning the diskand buying a scratch repair kit to fix the scratch (if its small) if the data on the disk is veryimportant to you.
With hard drives, CRC errors can be an indicator of impending hard drive failure if they keepappearing. Back up all important data just to be safe.
