that motherboard is probably a Sata type motherboard, you are using IDE which is only there for the DVD drives.
i suggest since you have already bought a hard drive that is IDE that you get a IDE to SATA converter.
befor you do this see if you do have a SATA slot..

you might be able to find a converter there. you will also requre a sata data cable. but you will be able to find a converter on ebay definatly!
if it is a IDE type then make your HDD master/with slave and dvd slave.
change the sequence that you have the drives on the IDE cable, you might have them in the wrong sequence. change the dvd one to the hdd and the hdd to the dvd.
