Hey - I just got to this problem myself - I'm only working w/ 1 CDRW disc too.... ARGH!!!!!! (refer to - create iso, burn cdrw, failure, erase cdrw, create....) Anyways - just found the answer through search w/ results via posts vs threads. http://www.msfn.org/board/index.php?showto...80entry194379 It's the Dosnet.inf problem that we're facing. After this next cycle i'll post if it resolves correctly.
