Cyclic Redundancy Check (CRC) is a data verification algorithm used primarily for checking the integrity of data on hard drives and optical disks (like DVDs and CDs). This algorithm comes into play when data integrity issues arise on a hard drive or optical disk.

Part 1

Step 1. Identify the cause of the error.

Step 1

Identify the cause of the error. A hard drive error occurs due to incorrect data writing. This can be caused by operating system malfunctions or power loss during data writing.

Step 2. To fix the cyclic redundancy error on the hard drive, run the "Check Disk" utility.

Step 2

To fix the cyclic redundancy error on the hard drive, run the "Check Disk" utility. In the "My Computer" folder, right-click on the affected hard drive and select "Properties."

Step 3. In most cases, this method won't work because not all disk properties will be displayed in the Graphical User Interface.

Step 3

In most cases, this method won't work because not all disk properties will be displayed in the Graphical User Interface. The interface may close without checking the disk. An alternative to this method is to run a command from the command line as shown below:

    1. Open the command prompt as an administrator.
    1. Type chkdsk G: /f /r (where "G" specifies the damaged hard drive).
    1. Launch the DiskPart utility from the same command line by typing DiskPart.
    1. Once the utility is running, enable the scan command. This command finds new disks that have been connected to the computer.
    1. Hope that the issue is resolved and you can access the hard drive.

Step 4. You can view the CHKDSK log by right-clicking on "My Computer" and selecting "Manage."

Step 4

Step 5. Right-click on 'My Computer' -> Manage -> Event Viewer -> Notifications.

Step 5

Step 6. No need to follow further instructions.

Step 6

Step 7. You will see a notification stating that you need to restart the computer to perform the check.

You will see a notification stating that you need to restart the computer to perform the check. Click on the "Schedule" button and then restart your computer.

Step 8. In the disk properties, go to the "Tools" tab and click "Check..."

Step 8

In the disk properties, go to the "Tools" tab and click "Check..." A small window will appear, ensure that the boxes next to "Automatically fix file system errors" and "Scan for and attempt recovery of bad sectors" are checked. Then click "Start."

Step 9. Note:

Step 9

Note: If an optical disk (such as DVD/BD/CD) reports a cyclic redundancy error, know that there is no way to fix it. If you burned the information to the disk yourself, try burning it to another disk but at a lower writing speed. The recommended writing speed is 4x, especially when you're burning an operating system (like Ubuntu or Windows). The higher the writing speed, the greater the chance of writing errors on the disk.
