Since RHEL / CentOS are server class OS, one can not expect ntfs support out of box.
If you are using these OS on laptop / desktop machines, you might need to access windows parition.
Running following two commands as root will enable ntfs support.
rpm -ivh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm
yum install fuse fuse-ntfs-3g -y
Mount Partition
e.g
mount /dev/sdX /mnt/win
