Adding an ATA to a F9 installed on a SATA drive

[redhatdude at bellsouth.net]

Hi,
I have a two 500 Gb ATA drives that I'd like to add to F9. This computer has the onboard socket for ATA, but F9 is installed on a SATA drive.
How do I go about formatting and adding these drives?
I'd appreciate a good howto tutorial on the web or step by step instructions here.
I've been using Fedora for years, but never had to do this.
Thanks,
EJ
