How to Fix Those Data Error Cyclic Redundancy Check Errors

If you keep getting the error cyclic redundancy check error (CRC), you need to understand what it is first before fixing it. This is a method used by computers to check for errors in a hard drive or optical disc (CD or DVD). The error message appears when the hard disk or optical disc is corrupted.

Make an Assessment
If the error is caused by your hard drive, it is probably due to data not being written properly on the disk. This is usually due to a corrupt or problematic operating system, but it can also be due to sudden power outage.

Fixes and Solutions
If you experience the problem with your hard disk, run Chkdsk or scandisk. Go to My Computer and right click the hard disk that is giving you the error. Choose Properties and run the disk checker. After running the disk checker you can find its logs by right clicking My Computer and going to Manage then Event Management and
Application logs.

If you can’t access Windows or the GUI becomes inoperable, then Windows can’t do the check on its own. Your alternative is to use the command line.

To use the command line, do the following:

Step 1
Run CMD using your rights as an OS admin.

Step 2
Type the following:

chkdsk C: /f /r ( 'C' refers to the affected drive; change if necessary)

Step 3
Type in the same prompt:

DiskPart

Step 4
Run the "rescan" command once the utility has been loaded. This utility will start looking for any disks that were installed in your computer and attempt to fix them.

If the error is caused by an optical disc, you have other options. If the error appears when you try and burn data, use a lower speed. Some computers and operating systems produce those errors when burning at high speeds.

CRC Cyclic Errors and Data Transfers
Those CRC errors often come up when the mathematical processes used for data transfers fails to work. When the computer performs the CRC check, it will verify if the data being transmitted is in good condition. If the error message appears, it is due to the fact that there is a problem with the data being transferred or there is a problem with the storage device.

CRC Errors, CDs and DVDs
The error often occurs when you try to copy data to and from a CD or DVD. Before the error message appears, there will be a whirling or grinding noise coming for the CD or DVD or your computer will slow down. The whirling sound is due to your computer’s attempts to read the disc numerous times unsuccessfully.

If after repeated tries it doesn’t work, the CRC error message will appear. Note also that this error message will appear if you try to get a file from the web that was not downloaded correctly. Sometimes this error message will also appear if an application or the operating system crashes.

If the problem is the disc, use a disc cleaner to remove the dirt. That should do the trick. If not, then try cleaning the disc drive, it might be dirty. Either one should resolve the problem.

As stated, the problem could be due to a faulty hard disk. But most of the time the error cyclic redundancy check error is due to the DVDs and CDs not being read correctly.
