How to Fix Cyclic Redundancy Check Data Error?

Part 1: Overview of Data Error (Cyclic Redundancy Check)

1. What is Cyclic Redundancy Check Data Error?

A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices. It helps detect accidental changes to digital data by attaching a short check value to blocks of data based on polynomial division. When retrieving the data, the calculation is repeated, and if the check values don't match, corrective action can be taken. CRCs are also used for error correction.

2. What Causes Cyclic Redundancy Check Data Error?

When a CRC data error occurs, it means that the calculated checksum of the received data does not match the expected checksum. This indicates that the data may have been corrupted during transmission or storage. The error can occur on different types of storage devices, including SSDs, hard drives, or even during file transfers over a network.

Below we've listed the possible causes of Cyclic Redundancy Check (CRC) data error:

• Corrupted partition, application, file, or storage device
• Connection to an unstable or faulty network
• Changes to file metadata or filename while in use
• Changes in the registry file
• Unexpected computer shutdowns or power outages
• Improperly connected hard drive
