How to Fix Cyclic Redundancy Check Data Error?

If you are reading this article then you’ve probably faced the challenge of fixing data errors connected to cyclic redundancy. It’s nothing surprising, really, because, by default, all operating systems generate data write errors or CRC (Cyclic Redundancy Verification) errors. For this reason, on many occasions when we manage or try to move data within any type of unit, a small pop-up appears with a clear error message. And here’s where the frustration starts.

How did come to this?


As we’ve already mentioned such errors can happen in different situations and during the execution of different applications. If you have software to deal with such errors, it will perform a complete analysis of what has happened, try to detect the problem, and propose a solution. If you still haven’t got such tool, Stellar info is the place to visit.

But, to return to the question in the subtitle. CRC error occurs when the hard disk is damaged, there are files with errors, bad configurations, corrupted log files, and incorrect software installation. The reasons can be multiple, but what is clear is that this error must be taken into account and evaluated for its repair as soon as possible. There are some situations where we will identify possibilities where such errors occur, and they are usually connected to the following:

– There is an error in the error data (cyclic inventory check).

– If there is a problem with CRC in Outlook due to failed folders, an error appears.

– Device not working due to CRC data error.

Binary encoding is very useful in various electronic devices; in this case, we are talking about disks or memories, in which information is encoded based on the presence or absence of an electrical signal. Within this whole process, there are some mechanisms designed to guarantee the level of integrity of this data through error checking.

What are these errors, how do they work, and what are the basic requirements for cyclic redundancy errors


How do we define these errors…Cyclic Redundancy Check is a data verification method used to review the data on our hard and logical drives. The method of cyclic contiguity verification consists of protecting data in blocks called frames. Each frame will be assigned a segment of data called a check code (or sometimes FCS, check frame sequence, in the case of a 32-bit string).

The check code consists of redundant data with the frame so that errors can not only be detected but also resolved. It is recalculated based on the recovery (or reception) and is compared to the originally transmitted value, which may indicate certain types of errors. For example, one bit corrupted in the data results in a single-bit change in the calculated CRC, but several corrupt bits may cancel each other out.

These redundancy verification errors can be generated for various reasons, including:

– Hard disk overload

– Errors in records

– Bad program installation

– Incorrect file configuration

We must consider this type of error because it is classified as a critical error and we must look for some solution to avoid potential data loss or even a complete failure of the operating system that uses all our productivity.

So, how do you fix these errors?

There are a couple of solutions one can utilize. Let’s take a look at what you can do…

1. Check for errors directly on the affected device

In this case, we will use Windows 10 as an example of fixing. The first step you should take is to go to the file browser, right-click the unit for analysis and select the Properties option from the displayed list. In the displayed window, go to the Tools tab and click on the Check button located in the Error Check section. The system will work automatically from this command.

2. Use the CHKDSK command


This command, short for CheckDisk, allows you to check the file system and file system metadata of a volume to find, analyze, and correct logical and physical errors. If we use this command without parameters, it will only display the state of the volume and will not correct any errors. If we use it with parameters s / f, / r, or parameters / b, we can correct errors in the selected volume.

3. Use third-party applications

We’ve mentioned in the introduction part that there are several software solutions you can utilize to protect your data from these errors, and they also contain the necessary tools for fixing them. There are a number of free tools that help us analyze disk or device errors and thus prevent cyclic redundancy errors from occurring. For example, the HDD scan app. This application allows us to perform a state scan of the affected disk or device to predict its degradation and thus prevent data loss and create file backups. It is portable and does not require local installation.

Some of the solutions found online can be downloaded for free, some come with a price. In any case, our advice is to go for the trial versions first and test a couple of these, before you find a suitable one that will answer your needs.

But, if you want to avoid having to install any app, the best way to overcome CRC failure is to perform disk defragmentation periodically, every month, or week. As it allows the data from the program or application to be located consecutively and next to the hard disk. You don’t even have to remember to do this, as the clean-up can be set to be performed automatically, as per your wishes.

These are some of the most suitable solutions to solve the problem of cyclic data redundancy checks related to data on all HDDs, external drives, or USB drives. We hope after applying the above solutions your disk drive will work normally or if it still has the same problem then I think it’s time to check the disk with the manufacturer.
