autofs should be auto adding it to the gnome left window ,under places .Once you click on the link it will automount in /media/?????
or you can add it to /etc/fstab
BUT selinux will through a "terrible 2's " temper tantrum if you try to mount a partition directly to "/"
CentOS has a folder for mounting partitions "/mnt"
make a folder in /mnt called " windows" and mount it there
