If it's showing up as /dev/hda, it's probably being accessed in legacy IDE compatibility mode or some such thing. Check your BIOS. (With CentOS 3, any time I upgrade the kernel, I have to switch my SATA drives into legacy mode before lilo will write the boot sector properly, and then switch them back again when rebooting.)
