Fix Cyclic Redundancy Check Error

Cyclic redundancy check (CRC) is an error message that appears on the computer screen whenever your PC reads corrupt data. CRC, basically detects an error in the file that is being read by your PC. This error message commonly occurs when your PC attempts to read data from a damaged storage media, such as a hard drive, CD or a DVD. When data is being transferred to the PC, cyclic redundancy check ensures that data with numerous errors does not reach the specified destination. This is the reason why a corrupted CD does not get copied onto your computer. Remember, data management is an important part of maintaining your system in the long run.

Fix Cyclic Redundancy Check Error
Many a times, accumulation of dirt on the CD or DVD causes a CRC error. Cleaning this storage media using a soft cloth often solves the problem. A scratched CD or paper labels on the disc can also be an issue. This is because scratches or labels do not allow the disc to burn properly. Partially burnt CDs are especially responsible for causing this error. For extracting information from damaged discs, there are software applications useful in this regard. These are tools that recover data such as lost digital images from corrupted CDs and DVDs.

Hardware Issues
If the CRC error is still displayed even after running a cleaned disc, then most probably the problem is with the hardware. You need to check your CD and DVD drives and clean them regularly using a lens cleaner disc. Find out whether these devices are functioning properly. Replacing the CD/DVD reader with the new one might solve the problem. Sometimes, connections of DVD and CD drives are lost that may interfere with the functioning of the devices.

Cyclic redundancy check error can appear due to other reasons too. Although a failing drive or a damaged CD are the common culprits behind the occurrence of this error, some other unavoidable circumstances listed below may cause this problem.

• Incomplete downloads
• System crash
• Buggy software (applications with plenty of bugs)

In such cases, the system may display messages like 'An invalid Windows file or an invalid win32 application'. But it is actually a CRC error.

Cyclic Redundancy Check Repair
A file that is not properly downloaded from the Web or an interrupted file transfer can also lead to CRC errors. So before you open the file, check whether it has been downloaded completely. You can use a download manager while downloading to fix cyclic redundancy check error. A download manager application keeps a track on the downloading process and informs you when it is complete. Or else, you can again attempt to download from the start and check whether it still occurs.

In case you are copying the file from your hard drive, you may have to run a scan disk program to troubleshoot errors related to the hard drive. Defective connections between the computer and the hard drive causes popping up of CRC message on the screen. For fixing CRC errors related to networking issues, you need to verify all the connections to decode the problem.

Remember, to fix cyclic redundancy check error, you need to determine the underlying cause. This is the best approach to get rid of this error message.
