Solved Getting CRC (checksum) error uncompressing 11GB WinRAR file

Winrar 4.00, x64 bit, archiver & compres...
August 11, 2015 at 01:05:03
Specs: Windows 7, I5, 4 GB
1) We have an 11 Gigabyte RAR (WinRAR) file.

2) When we try to uncompress the file we are getting a CRC (checksum) error.

3) We are using the latest version of WinRAR.

4) The WinRAR repair utility is not working on the file.

5) We are unable to extract the and keep it even if it is bad (WinRAR allows you to do this sometimes...extract without confirmation does not work).

Any help would be appreciated!!!!

Sounds like the file is corrupt. That's what CRC checks are for. You can attempt the repair, but I've never seen one work. .sfv files help, but they must be created with the archive.

Truth is, there really is no fix for a corrupt archive. If the decompression utility cannot match the CRC value, it doesn't know where to start in the file.

Good luck.

Not sure if it will be of any help but you can try another utility called 7zip, i find this to be a lot better than WinRar

A CRC error means that the WINRAR file data integrity is not valid. The best thing you can do is compress the files all over again.
