How do you put together damaged .rar files

I have downloaded win2k and its a pain the arse to unrar into an iso. I keep getting r05 r06 r08 r21 is bad, I try to fix them in winrar and it reports some good, but some it just asks me to restructure or something. If anyone can help me figure this out I would appreciate it. Thanks!!


The only way to fix it is to download the damaged files again. You cannot repair bad files satisfactorily.
