Soccerman--If you just did the kwik, and haven't rewritten to it, you probably can get most back.  I can't remember the name of the program...SCSI Mechanic?  something tools?  I dunno, I just remember comments on a NG a couple years ago.  I've never used it.  Might have a look at cdrinfo, Andy McFadden's site or links from it, or "heaven forbid"...Richter's junk.
