It makes no difference which way they go on except copying from cdrom to hard drive may be less efficient if they are both on one controller. I would put cdrom and cdrw on secondary controler because if you are copying cds you will use a temp file on hard drive and _not_ do an on the fly copy unless it is a data only cd. Even then the runout blocks can cause trouble. I would put cdrw as secondary master and cdrom as secondary slave. That way digital extraction from either cdrom or cdrw to hard disk will run at full speed. Note that if a cd is hard to read and you are doing an on the fly copy without using a temp file and the source disk spins down you get a frisby so use temp files on hard disk to do cd copies.
