Data Error (Cyclic Redundancy Check) – What is it?

The message “Data Error (Cyclic Redundancy Check)” will appear if something has happened to cause damage or corruption to your hard drive. Whilst it sounds bad, it can often be fixed. The error usually appears when a user accidentally shuts down their PC, disconnects their hard drive from the motherboard or knocks the hard drive accidentally whilst files are being written to the disk.

Common symptoms include:

  • Inability to use the hard drive whatsoever
  • Potential for Windows to cease operation at any time

There are a few methods that can be used to address the Data Error (Cyclic Redundancy Check). Each method will be used for a different scenario, so whilst you may not be able to completely revert your hard drive without additional tools, there should be a method to fix the issue or at least collect your data. Whilst this issue can be resolved at home, you may want to consider hiring a certified Windows technician or a data recovery expert.

Error Causes

Data Error (Cyclic Redundancy Check) can be caused when anything is done to interrupt the hard drive whilst it is writing files.

Further Information and Manual Repair

To fix Data Error (Cyclic Redundancy Check) manually, you’ll need to be able to access the hard drive from Windows. If you can boot into Windows with your faulty hard drive for a short while then you should find the method below far easier. If you cannot  boot into Windows from your hard drive, there are other methods available but they will require additional tools, such as an extra Windows machine or a utility tool.

If you can boot into Windows, even if it’s temporary, you will be able to use Method One to fix your hard drive. If you cannot boot into Windows, you’ll need to use Method Two. A third method is available that has the potential to fix the issue too.

Here are the top methods for addressing Data Error (Cyclic Redundancy Check):

 

Method One:  Run chkdsk from Windows

 

If you can boot into Windows, follow these steps to resolve the issue. As soon as you boot into the Windows start screen, open the Start menu. Search for My Computer and make note of your disk drive name. It should have a letter alongside it’s name. Typically this letter will be c, d or . It depends on how many other hard drives you have in your machine.

 

Next, search for and open cmd. Once the cmd window opens, type chkdsk /r c. Next, reboot your PC and let the chkdsk feature run. This has been reported to take anywhere between 2 to 48 hours to fix, but the issue should resolve afterwards.

 

Method Two:  Use another Windows PC

 

If you cannot boot into Windows with your faulty hard drive, you will need to use a secondary Windows PC to resolve the issue. First, make sure your PC is off and take out the faulty hard drive. Next, plug the faulty hard drive into your secondary Windows PC via sata cable. Once plugged in, turn on your secondary Windows PC.

Next, follow the steps listed in method 1, but make sure you choose the right hard drive.

 

Method Three: Use An Automated Tool

 

If you cannot fix the issue yourself, there are tools available that could potentially fix the issue for you. These tools also provide support for other Windows errors and bugs.  If you’d like to consider such software, you may like to download and install this powerful automated tool.
