The cyclic redundancy check (CRC) consists of a data verification method that our computer uses to verify the accuracy of the data present on the disks , from hard drives to optical disks, as could be the case with a CD or a DVD. In this way, it is useful to detect accidental changes in data that has not been processed.
However, a cyclic redundancy check error can occasionally occur, which can arise as a result of hard drive damage, corrupted log files, incorrectly configured files, incorrect installation of a certain program, or when there is a point of failure. on the device.
Even though, as we can see, it is originally an incident with a specific cause, the error is a serious problem, which must be resolved quickly to avoid system failures . Most importantly, reduce the risk of data loss .
The cyclic redundancy check errors that can arise are usually: drive data not accessible error (cyclic redundancy check); data error (CRC) in Outlook due to corrupted personal folder; or the cyclic redundancy check error on an optical disk.
Fortunately, there are few options available to solve these types of problems. And we explain what you can do if any of them arise.
How to solve the cyclic redundancy check error?
Running the CHKDSK utility
CHKDSK consists of a utility built into Windows that scans and repairs drive errors, being able to find and repair a series of small errors, as well as file corruption that could be the real culprits of the cyclic redundancy error.
To open it, we only have to go to the unit we want to verify, by right-clicking on the unit in question , and then click on Properties , Tools , and in the Error checking tab we click on Check now . We choose whether we want the utility to carry out a basic scan or an advanced scan (which could take a few hours, while the basic option takes between 15 to 20 minutes at most).
For the scan to start, you need to restart your computer . Of course, in case we suspect that the error may originally come from our hard drive, it is advisable to make a backup copy of the data before proceeding with the analysis.
We wait for the utility to finish the scan . Then the application will offer us a report and restart the computer. In case CHKDSK is able to fix the problem, the utility will. However, if during the repair process the utility crashes and / or does not complete the process, the number of damaged files may be very high, so CHKDSK simply will not be able to repair them.
In the event that this occurs, you have no choice but to try any other third-party disk analysis and repair utility. Or, good, change the unit that has broken.
Running SFC Scan
SFC stands for System File Checker, a utility used to repair Windows system files, including registry files or DLL files. This option is very useful when a corrupt file system, or some log file itself, is to blame for the cyclic redundancy error.
This utility is able to find the existing problem in the file and replace it with a new one . The process tends to take between 5 to 20 minutes, which will depend on the size and volume of the files to be analyzed.
To run this scan, we must connect the storage unit that we want to analyze, click on the Windows icon to open the search bar, and in that section we write cmd . Then, we right-click on Command Prompt and select the Run as administrator option. Now, in the cmd window, we type sfc / scannow and press the Enter button. The scan will start immediately.
Once it is finished, we must restart the computer and try to access the files from the storage medium. In case the problem persists, the only option left is to use a data recovery tool developed by a third party.
