Thanks for the quick reply - I've used Quickpar before, but was under the (possibly mistaken) impression that I needed to at least have the problematic .rar files in order to repair them. (The problem I have is that my newsreader (News Rover) can't form the .rar files as large numbers of the messages in those two parts are missing)

Like I mentioned in the first post, I'm a Usenet newbie - is there a way to form the .rar files manually when a large number of the messages that form the .rar file are completely missing? (or will the par files completely build the two missing .rar files when I begin the scan?)

Thanks again for the help and work!
