I believe most recent distros boot from a 2.4 kernel by default during installation. 2.6 kernels have support for SATA.

No Shakthi Fedora Core comes with 2.6 kernel so that could not be the problem. I too had faced similar problem with slackware but when I reinstalled it everything was fine. Hopefully there's a better solution. I googled around on it though I didn't find any relevant answers, IMO, but most results suggested problems with hardware so you might need to check if some of your hardware isn't supported by FC4.
