IDE installation of DVD writer

My motherboard supports four IDE devices. I have my hard drive on IDE 1. I have a Liteon cdwriter and a Liteon dvd rom/cd writer combo on IDE 2. The Liteon installation Guide says they strongly suggest that the DVD writer that I am trying to install be on IDE 2 and be set to Master. However, they also said the same thing for the cdwriter and the dvd rom/cd writer.

If I install the DVD writer as slave on IDE 1 with the hard drive, which seems to be the only option unless I move one of the other units, will I run into problems?

quite possibly your hard drive speed will slow dramatically. suggest you keep primary ide for hard drives. dvd burner as master on secondary ide, dvd/cdrw combo as slave on secondary.
