A cyclic redundancy check is a technique used to check for errors, especially targeting hard drives or optical drives. A related data error can occur if data on the hard drive or DVD is corrupt. You will then receive the error message: Data error (cyclic redundancy check). In this article you can read what you can do about it.

Steps

Fix a Cyclic Redundancy Check Error Step 1

Step 1. Check the cause

If the CRC data error is reported by the hard drive, the cause is probably data that has been incorrectly written to the hard drive. This can be caused by a corrupt operating system or a power outage.

Step 2. To fix a CRC data error related to the hard drive, you can use the CHKDSK application

Right click on the hard drive giving the error. Then click on "Properties".

Step 3. Often, however, you do not get to see all the properties in the previous way

The alternative is to open a command prompt window and run the following commands:

  • Run CMD as Administrator

  • Type chkdsk G: /f /r (replacing 'G' with the letter of the disk giving the error).

  • Launch the DiskPart utility. In the same window, type: diskpart

  • When DiskPart has started, type: rescan. This command checks for new drives connected to the computer.

  • You should now be able to analyze the disk.

Step 4. View the CHKSDK utility logs as follows:

  • Double-click My Computer, then right-click the hard drive you want to check. Click Properties and then click Utilities. Under Error Checking, click Check Now.

  • A message will now appear stating that you need to restart the computer in order to carry out the check. Click Yes to schedule the disk check and restart the computer.
  • Go to the options and click on the 'Check now' button. Check 'Automatically check file system errors' or 'Find and repair bad sectors'. Then click on start.

Step 5. Burn a new CD or DVD

If the optical drive gives the error message, there is no way to fix it. If you burned the CD or DVD yourself, you can try burning the data again on another disc, but this time at a slower speed (4x is the recommended speed). The higher the burning speed, the greater the chance of errors.
