When browsing Windows related forums, I find many users are discussing the “data error (cyclic redundancy check)” problem. They are in a hurry to find reliable solutions to remove this cyclic redundancy check error. Now, in this post, I would like to introduce what is data error (cyclic redundancy check), and how to solve this issue.
What is cyclic redundancy check?
According to Wikipedia, “a cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data. Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents. On retrieval, the calculation is repeated and, in the event the check values do not match, corrective action can be taken against data corruption.”
Why cyclic redundancy check error appear?
Normally, this error is often cause by various factors, including registry corruption, misconfigured files, cluttered hard disk, power loss, etc. However, whatever the reason is, the cyclic redundancy check error is a serious problem that should be addressed immediately to avoid potential data loss.
So, what should you do if you receive data error (cyclic redundancy check)?
How to Remove Data Error (Cyclic Redundancy Check)
It is strongly recommended recover data from the inaccessible drive with CRC error at fist and then try best to fix data error (cyclic redundancy check).
Now, how can you recover lost data and completely solve this error?
How to recover data from inaccessible drive with data error
Guess you may have found that data recovery software is the first choice when it comes to recovering lost data from drive with CRC error or other errors. Here I think MiniTool Power Data Recovery is a wise choice, for its Damaged Partition Recovery module is really very powerful as far as I know. This all-in-one program can be worked in Windows XP/Vista/7/8/10. Besides, as it is only a read-only software, you can totally rely on it for it won’t change any data of the hard drive.
After installing Power Data Recovery to computer, do the followings:
Step 1: Launch it and enter Damaged Partition Recovery.
Step 2: Full scan the target drive which reports data error (cyclic redundancy check).
Step 3: Filter and save all needed files to a safe place.
See! With only three simple steps, data on CRC error drive is saved, as long as the drive is not physically damaged. But there is a 1GB data recovery limitation for this freeware, you may purchase a paid version to break this limitation. All up to you.
How to fix “data error (cyclic redundancy check)”error
Next, it’s time to fix cyclic redundancy check error with Windows built-in Utility.
Step 1: Right click the drive that keeps saying cyclic redundancy check, then choose Properties -> Tools. Next, click “Check Now…” under “Error Checking”.
Step 2: Tick “Automatically fix the file system errors” and press Start to do a basic check and automatically repair the problems it has found.
Here is another alternate method to fix data error (Cyclic Redundancy Check) you can have a try, that is using CHKDSK:
Step 1: Run cmd as administrator to have the full privileges.
Step 2: Type “chkdsk /f x:” and press Enter. The letter “x” should be in accordance with the drive you’d like to run the scan on.
Step 3: Wait for the scan to complete. Once it is finished, CHKDSK will show you report and restart your computer.
Sometimes, you may happen to meet “Data error (cyclic redundancy check)” in Outlook. To solve this issue, you may first try using MiniTool Power Data Recovery to recover lost Outlook emails first, and then check hard drive to fix CRC error. Finally, re-create these folder/files. However, if data error happens on CD/DVDs, that is another situation. Please visit this original post to get answers.
What You Should Keep in Mind
Now you should have a general upstanding of what cyclic redundancy check is and how to deal with this CRC error. At the end of this post, I would like to stress how to remove “data error (cyclic redundancy check)”. Please keep in mind that you should carry out data recovery at first before you try to fix this problem. For any carelessness/fault will lead to data loss. If you receive the warning “data error (cyclic redundancy check)” and your drive contains some necessary data, the first thing you need to do is transferring all data to another safe place.
As data loss happens often, we suggest you to make backup often. You can use Windows Backup and Restore to do this or you can use third-party software to copy disks
