Hooking Up?

I need to hook up a hard drive, CD-RW, DVD, and ZIP. I hooked them up like this

Primary master=Hard drive
Primary Slave=CD-RW
Secondary master=DVD
Secondary slave=ZIP

I don't think i'm supposoed to have the CD-RW and DVD on the same cable (it won't burn stuff, gives me messages that it might mess up). How would i hook them all up to make everything work and make it so I can burn things.

P.S. The way I have it hooked up is not working, too tired to screw with it. HELP?!?!
