Data Error Cyclic Redundancy Check Error | What & Why

It's also essential to figure out what the Data Error Cyclic Redundancy Check (CRC) is:

# Definition: According to Microsoft, a 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 the 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, and not initialized.  

The "Data Error Cyclic Redundancy Check" error could be caused by the following reasons:

• A corrupted file system on storage devices
• Registry corruption
• Interrupted file transferring process
• Misconfiguration in files and storage devices
• Unsuccessful program installation
• Misconfigured system files
• Virus or malware infection
