Redhat 9 is so old, it belongs in a museum.
SATA did not exist when RH9 was released, so you are on a hiding to nothing trying to install it on a SATA hard drive. It simply will not work.
I suggest that you get a recent distro. The latest in the Redhat line is Fedora Core 6, alternatively try Ubuntu Edgy or any other current distro.
