Cyclic Redundancy Check is usually caused by faulty storage media, bad sectors, interruption in file transfer process, corrupt files, failing hard drives, or loose connections. Cyclic Redundancy Check arises when the system checks for errors and the calculated CRC does not match the CRC stored. This means that the data has been changed or corrupted. To solve the problem, check the connections on the drive, test the storage media on another computer if possible, and perform disk diagnostics using built-in tools.
