Winrar CRC error when extracting multivolume file parts?

Have you ever tried to download a massive multi-volume file parts from a site, especially from Rapidshare? Well, if you do and tried to extract those files and get a CRC error (a.k.a corrupted file archive) from WinRar, you'll probably trying to figure why does the error occured while the file size is correct? To no avail, you might re-download the file again. I can tell you that your effort is futile.

Well, try using 7-zip and your problem will be solved. In fact, if you extract those files again using 7-zip, you'll notice that there is NO CRC error or corrupted files indeed for those files.
