Check the cause. In the case the CRC error was thrown by the hard drive, the causeis likely data being incorrectly written to the hard drive. This can be caused by either

the operating system being corrupt, or a power loss.

To fix a hard disk CRC error, run the CHKDSK application. In the "MyComputer" 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 theproperties 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:

. Run CMD as an Administrator

. type chkdsk C: /f /r ( 'C' signifies the affected Drive).

. Run DiskPart utility from the same command prompt type DiskPart

Enter the "Tools" tab and click the "Check Now" button. A small windows willappear, make sure the "Automatically check for filesystem errors" box and the "Find

and repair bad sectors" 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/CDdisk) is reporting a CRC error, there is no way to fix this. If you burned data to the disk

yourself, try burning said data to another disk, this time at a lower speed. 4x is therecommended speed, especially when burning operating systems (i.e an Ubuntu LiveCD)to a disk. The higher the speed at which the data is burned, the higher the chances errorsmay be written to the disk.

Disks may throw CRC errors if there is a smudge or scratch on the disk. Try cleaning thedisk and buying a scratch repair kit to fix the scratch (if its small) if the data on the disk isvery important to you.

With hard drives, CRC errors can be an indicator of impending hard drive failure if theykeep appearing. Back up all important data just to be safe.
