In 1961, the American mathematician William Wesley Peterson developed cyclic redundancy checking (CRC) to reduce errors occurring when transmitting and storing data. In this procedure, redundancies are added to each data block in the form of an additional test value. This value, also known as the CRC value, makes it possible to detect errors that have occurred during transmission and storage and would ideally correct them automatically.
If the cyclic redundancy check encounters at least one problematic file, a CRC error may occur that prevents the scheduled data storage or transfer from being executed. This can occur especially when downloading and extracting compressed files and archives. However, it can also happen when reading and writing data to hard disks. In this article, we’ll discuss what a CRC error is and how to resolve the problem.
