thank you flexodl. it's works
raed1964 yes it works but with the way flexodl said.

anybody downloaded this and succeeded extracting them?... its too big for me to risc a dead end..

Here is how to fix the dreaded CRC / Volume is corrupt error when trying to extract Rar files.

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.

and it will successfully extract the file into your folder and will be ready to be used.

part 11 is corrupt (downloaded twice)

I watched this 3-4 times complete season!
Great show!
