Help!!! Multiple HDD setup

[lanneretwing]

Hello,
I am trying to build a new system with 1 SSD and 2 HDD all sata on my new asus z67 mobo. I installed windows with AHCI mode. Everything is fine, however 1 of my HDD shows up as the wrong size and diskmanagment cant initilize it, But if i go to bios and set AHCI to IDE all 3 works fine!!!!! why is that? both bios and intel rapid storage sees all 3 harddrives fine. it's only that one HDD that's giving me problems. Any Help is appreciated thanks
