Fix 1. Fix Cyclic Redundancy Check Data Error via CHKDSK
The CHKDSK utility in Windows scans and repairs file system corruption and bad sectors that caused the cyclic redundancy check data error on your device.

Step 1. Press Windows + S keys, type cmd in the Search box.
Step 2. Right-click Command Prompt, and select "Run as Administrator".
Step 3. Type chkdsk F: /f or chkdsk F: /f /r /x in Diskpart and hit Enter.
Replace 'F:' with the drive letter of your hard drive with the Cyclic Redundancy Check error.
Step 3. When the scan completes, type exit and hit Enter to close the window.
After this, you can restart the computer and see if your device is accessible and workable now.
Fix 2. Fix CRC Data Error using Disk Check
The Disk Check utility in Windows can also help to fix file system errors that caused your device inaccessible with Cyclic Redundancy Check error. Here are the steps that you can apply to fix the CRC error from your drive:

Step 2. Under the Tools tab, click "Check" at the Error-checking section.
Step 3. Choose "Scan drive" or "Repair drive" if errors were found.
When the scanning finishes, restart the computer and check if you can reopen the device and use the saved data again.
Fix 3. Remove CRC Error with System File Checker

Step 1. Press Windows + R keys, type cmd in the Run dialog, and click "OK".
Step 2. Type DISM.exe /Online /Cleanup-image /Restorehealth and hit Enter.
This will make a Windows image to protect your data.
