A Cyclic Redundancy Check (CRC) is an error-detecting code used in networks and storage devices to check for any accidental changes to raw data.
When chunks of data enter a system, they are given a short check value based on the remainder of a polynomial division of their contents. At the receiving end, the same calculation is repeated and if both the values do not match, corrective steps should be employed to tackle data corruption.
A Cyclic Redundancy check could be caused by various issues including registry corruption, unsuccessful program installation, cluttered hard drive, or misconfigured files.
Let us look at ways in which we can solve the CRC errors.
- Using CHKDSK
CHKDSK or Check Disk is a built-in Windows utility that scans and repairs your drive’s errors.
- Click on Start
- In the search bar, type cmd and hit Enter.
- A Command Prompt window opens. Type chkdsk D: /r (you can replace D with the hard drive you want to scan).
- Change Drive Letter
- Click on Start
- Now type Control Panel in the search bar.
- Click System and Security.
- Now select Administrative Tools.
- Double click on Computer Management
- Now click Disk Management under Storage in the left side of the window.
- Identify your external hard drive on the right side.
- Right-click on it and select Change Drive Letter and Paths.
- Go for Change Pick new letter from the list.
- Click on OK once the process finishes.
- Format your hard drive
Formatting your hard drive gets rid of all the errors. It also means you will lose data present on the drive. It is advised to first recover all the data to a different storage device and then format the drive.
Data recovery using Remo Recover software
Remo Recover software shows you in few simple steps on how to recover data from external hard drive showing crc error.
The software can recover data from file systems such as FAT16, FAT32, NTFS, NTFS5, and ExFAT. You can also restore data from internal and external hard drives, USB drives, Memory cards, FireWire Drives and so on.
Remo Recover helps you restore data from lost, deleted, formatted and re-formatted partitions or drives as well.
