only access 13 gb out of 40 gb hard drive from rh 9.0
 

i have a 40 gb hdd installed as pri. master on my system. i installed rh 9.0 on it. everything works fine. but i can only access around 13 gb of my hdd.
5 gb /
5 gb /home
384 mb swap
3gb as fat32 which i have mounted on /mnt/fat32

how do i access the rest of my hdd. its not a partitioning problem. because i did mkfs.msdos to make the fat32 partition. it only gave me the above mentitioned 3 gb.

Post the output of the console command:
fdisk -l (thats a small L and you need to be logged in as root)

how old is your motherboard?
a 20gb harddrive might not be supported by your motherboard, try upgrade your firmware if that's the case.
go into your BIOS and check if it recognized your hard drive as a 20gb hard drive just to make sure
