Data Error Cyclic Redundancy Check error cause a lot of annoyance. CRC or Cyclic Redundancy Check is a check performed by the file system to see whether the file was copied or not without any errors. Some use each bit comparison to complete the check. While some checksums are generated and then they are compared to see if the files are the same.

Data Error Cyclic Redundancy Check

Copying data is an integral part of our everyday work. And it can encounter problems because of corruption in either the source or the final destination of the file. If the files showing this Data Error Cyclic Redundancy Check error are essential to you, we urge you to keep a backup ready for them. Its regrettable to encounter data error in order to fasten things up. You end up creating an error that slows you down instead.


How to Fix Data Error Cyclic Redundancy Check in Windows 10, 8 and 7

Solution 1: Repairing the Whole Drive

Chkdsk is a command that is always useful when it comes to fixing problems with the Drive. Chkdsk is a built-in windows command to repair the corrupt registry and bad sectors to be used in the command prompt.

Step 1 – Firstly, open “Run” using Windows + R.

Step 2 – Secondly, type in cmd and press Ctrl + Shift + Enter to open a command prompt with administrator privileges. Ensure that you have terminated all the background processes so that the applications don’t interfere in hard drive repair.

Step 3 – Then, enter the command “Chkdsk /f d:” replacing d with the letter of the Drive to be repaired.

Step 4 – Allow the process to complete, and the command prompt displays the result of the process and repair the Drive if needed.

Its highly likely that all the errors of that Drive have been fixed, and copying data can be done without the Data Error Cyclic Redundancy Check error. If this is not a viable Solution, then it is recommended to format the Drive.

Solution 2: Format the Corrupted Drive

Formatting anything is always a credible option. Formatting has the only downside of clearing all your data. If your corrupted Drive is beyond repair, formatting the Drive seems to be the only option left. Follow this simple guide to format your disk. Create a backup of your data, if possible.

Step 1 – At first, open “This PC” from the desktop shortcut.

Step 2 – Or open File explorer and go for “This PC” present in the left pane. Then, right-click on the drive icon. After that, select “Format Drive.”

Step 3 – Now, press OK to give confirmation. Quick Format needs to be deselected to be able to clean the Drive efficiently.

Step 4 – Next, select NTFS if the Drive is a hard disk or FAT32 if using pen-drives or memory cards as the partition system.

Step 5 – Once the Format is completed, you can go for copying data and check if the error still persists.

Solution 3: Renaming the Drive (Assigning a drive letter) if a Drive is Not Accessible

Windows always automatically assign a drive letter to a newly connected drive. Similarly, it automatically deprives the same Drive when it remains unused for a long time. If this is the reason for this error, we can always assign a name to the unnamed Drive and access it then. Its imperative that you be careful not to disturb small partitions that are reserved for the Windows operating system’s safe operation. It may end up ruining your PC.

Step 1 – Firstly, open “Run” using Windows + R. Then, type “diskmgmt.msc” and press enter to open Disk Management tool.

Step 2 – If you can observe a drive that seems to be the one in question, just rename the same by right-clicking on it and assigning a letter to it.

Step 3 – In the menu that appears, choose Change drive letters or paths. If a letter is already assigned to it, then change the same; if not, choose to add another letter.

Step 4 – Give a new letter to your Drive, which is not already in use.

Step 5 – Reboot your PC.

Solution 4: Check for Bad Sectors on a Hard Disk

The data error cyclic redundancy check is one type of errors. It is potentially caused by a driver being corrupt, and it is definitely the perfect time to replace it. Drive can get corrupted due to a variety of reasons. For example, a mechanical failure which in turn is due to forcibly shutting down the system, or physical damage such as dislocation of the Drive. Or the reason could be as simple as being ejected during data transfer. These problems may seem trivial, but they have an everlasting effect.

We have to take the help of third-party partition tools for checking and, if possible, fixing the corrupt sectors of the disk.

Step 1 – First of all, open the tool and right-click on the Drive that seems to be corrupt.

Step 2 – Then, choose the option that ultimately scans for bad sectors. Wait for the scan to be complete and patiently let the tool scan even if the system hangs.

If it freezes for a long time, your Drive is beyond repair and needs to be repaired.

Solution 5: Recover the Source Files

Each and every file in the system has a secret file that contains the metadata of the file. Some third-party applications available on the internet helps you recover the bad sectors of the file. Not every byte is deleted upon when you delete or move or overwrite a file from a disk. The metadata about the files and folders deletes its entry instead.

The third-party application can be a paid one or can come up with a free trial that rebuilds the metadata file. This makes the corrupt file available again. Check out the best data recovery software.

Step 1 – First of all, terminate all the background processes involved.

Step 2 – Second of all, run any recovery software with administrator privileges. Then choose the Drive you want to recover files from.

Note: Be particular about the type of files, whether it’s a jpg, an mp3, or any other.

Step 3 – Select the Drive where you want the recovered data to be stored and wait for the process to complete.


Final Words

It is important to know that we can only do so much. If there is a persisting error with your Drive, even after following all the Solutions, you need to go for the backup plans as the Drive is beyond repair. Always make sure you have a warranty of some kind that helps you get out of this mess with minimum damage.

However, we are sure that if there is a small chance of tackling this error and the Drive can be saved, these Solutions are the best possible way to do it. Remain patient and let the processes complete and hope for the best.
