Additional info:
I have an AMD athlon 64 bit processor (3500+), SATA disk & performed a network 
installation. I also changed the default name "Fedora Core" in the boot menu 
(during install) to "Rawhide".

Following was my disk structure
/dev/sda1 - / - 80000 M - EXT3
/dev/sda2 - swap - 512 M
/dev/sda3 - /data - ~=70000M - EXT3
