In this piece of article we are trying to educate the Windows users regarding the “Cyclic Redundancy Check” error. The error causes as well solutions are explained herein detailed manner. In brief, here you will find out about—
Cyclic Redundancy Check (CRC) is the term used for the method of data verification used by computing devices to keep a check on the accuracy of data. The CRC system tracks the changes taking place in the raw data which is stored in the storage media.
The CRC errors simply define that malfunctioning of non-functional behavior of CRC. This can happen due to the corruption of system registry file, interrupted software installation, poor file configuration, or hard drive errors. CRC error is quite a noteworthy issue which needs to be resolved on an immediate basis or else it would end up damaging your system and causing you loss of data. So, let’s get started without wasting any further second—
The Error Message You Get
“File xxxx.pst could not be accessed. Data error. Cyclic redundancy check.”
Reason For The Error
This issue mainly originates from the corrupt PST file. The damage can occur due to bad drive sectors, damaged file system, virus, and malware.
The issue can be resolved using four different solutions. But first, you must close the applications in which PST files are being used.
Let’s Uncover the Troubleshooting Methods
Method 1: Recreate the File
This method is suitable only for those who can take the risk on data stored in the PST file. Make sure that the data stored in the corrupt PST file is not of your use and you can afford losing it. Once you delete the file, the issue will be resolved and a new PST file will be formed on your device. With this method, you can get rid of the issues but the data will be deleted along with the PST file. So, go for this method only in the case where the data stored in the file isn’t very crucial.
Method 2: Fix the Hard Drive Related Errors using CHKDSK Utility Tool
If the storage volume is creating the error, you can fix the error by scanning the volume using “CHKDSK” utility. This program in Windows is mainly designed to scan and repair the bad sectors, file system corruption along with other such factors that cause the cyclic redundancy check data error on your device. So, in order to remove CRC error, run “CHKDSK” utility tool on your device via following these steps—
- First, go to the Start menu>>All programs and type ‘cmd’ to open the Command Prompt app.
- Then, click right on ‘Command Prompt’ to ‘Run as Administrator’ option from the contextual menu.
- In doing so, a command prompt window will open and inside it, type the “chkdsk F: /f or chkdsk F: /f /r /x” in the Disk part and hit the ‘Enter’ button.
[Note: You have to replace ‘F:’ [drive name] with the drive letter of your hard drive which has the Cyclic Redundancy Check error.
- In doing so, the tool will rigorously scan the issue and try to fix it completely.
- Now, you can give a quick restart to your device to check whether your device is accessible and workable now or not.
However, if the CRC error continues even after running this utility tool, one can try repairing the PST file. Because the corrupt PST file can be another possible reason for this.

Method 4: Run SFC Scan
System File Checker is used to fix Windows system files including Windows DLL files, registry files, or other secure files. Sometimes due to the damaged file system or registry files, CRC (Cyclic Redundancy Check) error happens.
The SFC scan discovers the file issue and swaps the corrupt or damaged file with a new one. The whole process can take about 5 to 20 minutes reliant on the size and volume of the file. To start the SFC scan, follow below bullet steps:
- Connect the storage drive
- Tap the Windows symbol to open the search bar
