HI Goosha, the configuration you have really needs to be linked into how you have your IDE ribbon cables
you have 2 cables IDE 1 and IDE 2 for ease
both can have two devices attached to them, one must be a master and one must be a slave, the master will be on the end of the ribbon cable and the slave will be in the middle.
So on IDE 1 the master will be you Hard drive C:\ if it were me I'd have a DVDrom as the slave.
On the IDE 2 ribbon, you would have the DVD Burner as the master and the CDRW as the slave.
doing it as above, if you follow the logic the drives will be able to put info out and the writers will be able to accept it (in a data flow sorta way).
