Overview: What Is Data Error Cyclic Redundancy Check (CRC)
# Definition: According to Microsoft, Data Error Cyclic Redundancy Check, known as CRC error, indicates the operating system has found a drive with bad sectors or some intermittent problem on your storage devices.
# Symptoms: With Cyclic Redundancy Check error, you'll receive pop-up error messages as shown below.
- 1. "Drive is not accessible. Data error (cyclic redundancy check)."
- 2. "Virtual Disk Manager. Data error (cyclic redundancy check)."
# Result: Storage devices that contain the CRC error will become inaccessible, unopenable, RAW, not initialized.
According to EaseUS data recovery experts, you should recover data first as some fixes may cause file loss. Follow to remove the CRC error on your own.

Part 2. How to Fix Cyclic Redundancy Check Data Error - 5 Ways
Here we collected 5 practical methods that can fully help you fix the "Data error (cyclic redundancy check)" issue and make your storage devices function normally again.
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.
- Running chkdsk can hopefully fix the cyclic redundancy check error, however, it can also result in total data loss. So, perform data recovery in advance, and then continue with the CMD method.
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 4. 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 a Cyclic Redundancy Check error. Here are the steps that you can apply to fix the CRC error from your drive:
Step 1. On Windows File Explorer, right-click the inaccessible hard drive or device, choose "Properties".
Step 2. Under the Tools tab, click "Check" in 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
The other Windows built-in tool - System File Checker sometimes also works to repair the missing or corrupted system files on your computer. You can also apply it to fix the cyclic redundancy error resulted from system file corruption.
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.

Step 4. Wait for the process to completes, then type exit and hit Enter to close it.
After this, restart your computer and then you can reopen the device and make use of the saved data again.
Fix 4. Format to Fix CRC Error on RAW/Inaccessible Device
If your device became RAW or still has CRC device error after trying the above fixes, the last effective DIY method you can try is to format the drive. By resetting the file system to a readable format, the CRC error can be fixed. Here are the steps for you to go:
Step 1. Press "Windows key + E" to open Windows Explorer.
Step 2. Right-click on the problematic device with CRC error and select "Format".
Step 3. Select a suitable file system - NTFS or FAT32 for your device.
(NTFS for hard drive or external device; FAT32 for SD card for USB - 32GB or smaller.)
Step 4. Check "Quick Format" and click "Start".
