there is a bug (well not really a bug but...) with the latest versions of blindwrite that topologies read by most writers always give a topology quality of zero. I have the same problem with my premium and my litey 52x32x52x16x combo and my litey 40125s
Try a cd/dvd-rom to produce the topology or a way around it is to use the bwa builder and just after the 3rd clump cancel the reading. from there use the clean button and it will give you a topology the same as any other. Then use this when copying. Bw only needs the first clump (sorry about the technical wording here just can't think what to call it) to make a good copy. You can then use you premium to finish the writing and hey presto a perfect copy.
If you cannot be arsed with all that rollback to 5.02 version (hence the stable version on their website) and just let it run like normal.
Or as already mentioned use a cd-dvd-rom drive. My ltd 166s works perfectly for this giving me 100% everytime. The i use my premium to write.
woooooooohoooooooo 500th post :eek:
