CRC Error

Problem

You can see the error message "CRC error" on the screen when you try to do either of the following:

  • During image creation, when there is an issue with the hard disk of the machine where image is created. 
  • During image creation/deployment, when there is an issue with the hardisk of the image repository machine.
  • During deployment, when there is an issue with hard disk of the machine where image is deployed.

Cause

A cyclic redundancy check (CRC) is a data verification method that your computer uses to check the data on your disks (hard disks like your hard drive and optical disks like CDs and DVDs). A cyclic redundancy check error can be caused by several different issues: registry corruption, a cluttered hard disk, an unsuccessful program installation, or misconfigured files. Regardless of the specific cause, the cyclic redundancy check error is a serious one and must be addressed to avoid potential data loss or even a total system failure system.

Resolution

To resolve this problem, follow the steps given below:

  1. Check hard disk peripherals 
    1. Ensure that the cable is properly plugged in.
    2. Check for any damage on the device.
    3. Ensure that the port is working.
    4. Try using the device on other machine.
       
  2. Run CHKDSK Utility
    1. To access the CHKDSK utility, right click the drive you want to check, then click Properties->Tools. Under “Error Checking” click “Check Now”.
    2. Select Basic or Advanced Scan. 

      Note : On newer version of windows the advanced search option may not be available.

    3. Reboot computer.

  3. Corrupted files
    1. Corrupted files can also be an error. Try formatting the drive.
    2. If needed you can also replace the drive.
