Fixing CRC error in an RAR file

Updated on January 8, 2014


As the technology enhanced, a simple file takes a large amount of disk space on a computer. So we need a tool to reduce the size of a file without affecting its quality while storing it in a secondary storage. An RAR File (stands for Roshal Archive) is used to compress multiple files or folders on a computer system to save disk space. RAR files can be created with any commercial softwares like WinRAR, RAR, etc. In addition, when we want to access the compressed files, these softwares can decompress or extract an RAR archive.

Problem Statement and Reasons

But there is a common problem with RAR File Format that while extracting files using any extracting tool like WinRAR, it generates a CRC Error so that users cannot access any of the file which are compressed in the RAR File. CRC error means that the disk has failed to perform Cyclic Redundancy Check. The main logic behind it is that there is a rotating checksum for each and every byte, when that checksum doesn’t match up because of any reason then this CRC message will pop up, and it will restrict the unzipping process of RAR files. While moving data, some noise might be added with code bits that leads to CRC errors. In addition, there may be various reasons for the problem:

  • Virus infection on the RAR file
  • Where the RAR file exists on hard disk contains bad sectors
  • While creating RAR file, power failure occurs
  • Corruption of RAR file due to recovery tool
  • File system corruption can cause inaccessibility of RAR file
  • While compressing several files to reduce file size using WinRAR, error occurred can cause damage and inaccessibility to files


There is a solution to fix CRC error using WinRAR tool:

  1. In the main RAR window when originally clicking the RAR file, click on "Extract To"
  2. Under Miscellaneous, check "Keep Broken Files" , Choose whatever folder on your computer you would like to extract the file into, then click OK
  3. During the extraction process, you will have the CRC errors pop up. Just click on "Close" every time it pops up

It will successfully extract the file into your folder and will be ready to be used. But it doesn’t guarantee that it will fix all the CRC errors. If it fails then you will have to use powerful RAR repairing software.

      Otherwise, if built-in winrar restoration wasn't be effective, you may look for a third-party recovery software, I would recommend you RAR Repair Toolbox from

      It will help you recover your maximum possible data from corrupt .rar archives. Other than recovery of corrupt .rar archives, it also supports recovery of corrupt .zip, .tar, .tar.gz and .7z archive.

      Guide is alright except it doesn't work.

      As for RegHunter, there isn't any option to repair RAR, it is purely for repairing registry issues but compared to the likes of Tuneup Utilities it pales in comparison.

      If it does have the ability to repair RAR files then it eludes me and if the writer of this article knows for sure that it does repair RAR CRC errors then it would be most helpful for it to be explained in full detail.
