Let’s say our algorithm is to simply add up the numbers representing our data. If the number calculates differently, then something’s wrong and you get a CRC error.

Later, the data can be read, the number calculated again, and if it matches the number stored originally, all is well.

It starts with a formula that takes the data in question, calculates a number, and then stores that number with the data. What’s a CRC error?Ĭyclic redundancy check, sometimes also called a checksum, is a fancy name for some complex math that detects when data has been damaged. Finally, consider whether you should replace the disk on which the error occurred. Use CHKDSK or try to repair the file with file-specific data recovery and repair tools. If the error remains, save a copy of the file, even with the error, and try to repair the disk using surface-scanning tools. If it copies without error, then the CRC error was in the previous destination, not the original file. Begin by trying to copy the file exhibiting the CRC error to another location.
