  • CRC Error: Cyclic Redundancy checks are used to confirm files integrity. You will never come to know whether the file is complete and error free until the file is extracted. While extracting the downloaded file is compared with the original CRC data which produces an error if the information does not match i.e if the checksum codes differ from each other while unzipping. Re downloading the file will fix the problem in some rare cases. But if the file is severely corrupted beyond usual repair then you have to use RAR repair software to fix RAR file CRC errors.
