5 Ways | How to Fix Data Error Cyclic Redundancy Check

To fix the Data Error Cyclic Redundancy Check issue on an external hard drive, USB, SD card, or HDD/SSD in Windows, follow these steps: Run the built-in Check Disk (chkdsk) utility to scan and fix errors, disable the floppy disk emulation, and check for bad sectors. If the issue persists, try running the command prompt as an administrator and use the chkdsk utility with the /f and /r options to force a scan and repair any errors.

Learn what the "Data error (cyclic redundancy check)" error is and how to fix it on your device in 5 reliable ways. This page will guide you through the process of resolving data CRC errors.

Overview: What Is Data Error Cyclic Redundancy Check (CRC)

# Definition: A Data Error Cyclic Redundancy Check, or CRC error, indicates that the operating system has found a drive with bad sectors or an intermittent problem on your storage devices, according to Microsoft.

# Symptoms: With Cyclic Redundancy Check error, you'll receive pop-up error messages that appear on your screen, indicating a data transmission error that occurred during the process.

• 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, and not initialized due to corrupted data.

Data recovery experts at Qiling recommend recovering data first, as some fixes may cause file loss, and then follow their steps to remove the CRC error on your own.
